Ovary ovoid 1-1.8 mm long, on a well developed disk, 0.25-0.6 mm high, glabrous; style 3-10 mm long, with cylindrical to narrowly ovoid, obtuse stigmas, 1-2.5 mm long.
Fruits:
Capsule globular to globular-ovoid, 4-8 mm long, 4-7.5 mm diameter, glabrous.
Habit:
Perennial with trailing and twining stems; stems terete, densely hairy to ± glabrous in younger parts, becoming sparser with age; hairs short, ± appressed, 0.2-0.5 mm long, in older parts becoming erect and spreading and up to 0.8 mm long, the relative abundance of erect and appressed hairs varying among subspecies.
Inflorescences:
Inflorescence solitary, axillary, bracteolate with solitary Flowers, very rarely a one-sided dichasium with 2 Flowers or with 2 inflorescences per axil; peduncle terete, 4-50 mm long, moderately to sparsely hairy, hairs mainly appressed, occasionally spreading; bracteoles opposite, rarely sub-opposite, linear, subulate to narrowly ovate, 1-4 mm long, 0.2-0.5 mm wide, apex acute, ciliate, moderately hairy to glabrous on the back; pedicel often darker than the peduncle 3-23 mm long, recurved at fruiting, hairs similar to and often denser than on the peduncle.
Infraspecific Characters:
Four subspecies are recognised and can be distinguished as follows.

1. Lower cauline Leaves broad and much divided with the terminal lobe more than 1.5 mm wide; lobes gradually becoming narrower towards the tip…………………………………. C. angustissimus subsp. angustissimus

       Cauline Leaves with narrow lobes almost from the base of the plant; lobes < 1.5 mm wide, or if wider then basal lobes spreading and clavate and terminal lobe distinctly obovate-clavate.................... 2

2.    Flowers 14-25 mm long; flowering pedicels 8-18 mm long; outer sepals moderately to sparsely hairy, usually ciliate at the tip; Seeds with sparse low reticulate ridges.........................................................

       ................................................................................... . C. angustissimus subsp. omnigracilis

          Flowers 9-14 mm long; flowering pedicels 4-8 mm long....................................................... 3

3.        Seeds smooth; sepals ± glabrous to sparsely hairy, with hairs mainly appressed, Leaves with ascending lobes often > 1/3 the length of the terminal lobe and lacking distinctive basal lobes………………………………………..…… C. angustissimus subsp. fililobus

       Seeds with sparse low reticulate ridges; sepals moderately to sparsely hairy with ascending and spreading hairs common; Leaves with ascending lobes mostly < 1/3 the length of the terminal lobe; lower cauline Leaves with distinct, spreading, clavate basal lobes.....................................................................................

       ................................................................................ . C. angustissimus subsp. peninsularum

Both C. angustissimus subsp. omnigracilis and C. angustissimus subsp. fililobus are reasonably distinctive but much variation is present within C. angustissimus subsp. angustissimus and C. angustissimus subsp. peninsularum. Because of the great variation, resulting from ontogenetic development and geographic distribution, and the influence of time of germination and length of the growing season on morphology, it is difficult to classify the existing variation on the basis of herbarium specimens. In addition, hybridisation further confounds attempts at classification. More field work will be necessary to clarify the variation which exists within these taxa.
Phylogeny and infrageneric relationships:

C. angustissimus most closely
resembles C. wimmerensis. C. recurvatus
has similar recurved pedicels subtending mature Capsules but its pedicels are much shorter than those in C. angustissimus,
its Flowers smaller and its inflorescences
often compound.

appears most closely related to C.
graminetinus. However, C. erubescens has a larger corolla and
longer, straight to sinuate, pedicels at fruiting while in C. graminetinus the pedicels are shorter and strongly recurved at fruiting.
For more than a century, C. angustissimus
was regarded as conspecific with C.
erubescens but the latter has a compound dichasial Inflorescence and a distinctly different Seed surface pattern which distinguishes it from that species.

Convolvulus crispifolius

General comments:

Though this species was described in 1853, the name has rarely appeared in print. Strangely, Bentham (1869) did not take account of the name and appeared unaware of its publication. Under C. erubescens Sims he remarked on a remarkable form or variety “¼.. with the Leaves very densely tomentose and much-cut and crisped and the peduncles very short from Cudnaka” which had been collected by Mueller. This specimen had been selected by Mueller as the type for the name of his species, C. crispifolius. Mueller (1864) wrote of the extreme variation existing within C. erubescens and reduced C. crispifolias (now spelt as C. crispifolius) to synonomy under C. erubescens. I was not aware of its existence until after C. eyreanus was described.

Distribution:

Australia (Queensland, New South Wales). Endemic.

Ecology:

It
occurs mainly on clay soils on alluvial plains with Eucalyptus coolabah and E.

clay soil downs with chenopods.

Editor:
George Staples, Esmond Er
Flowers:
Outer sepals obovate to elliptic or oblong, 3-5(-5.5) mm long, 2.2-3.8 mm wide, apex acute to obtuse-rounded with a short recurved apiculum, ± ciliate, ± glabrous to sparsely hairy, rarely denser, outside, hairs crisped, ± appressed to ascending, 0.1-0.4 mm long; inner sepals obovate, obovate-orbicular to broadly elliptic, 3.5-5 mm long, 2.5-4 mm wide, apex rounded, occasionally acuminate, with a short recurved apiculum, base rounded to truncate, glabrous or with a few hairs at the tip. Corolla funnel shaped, pink, occasionally white, with a greenish-cream throat, 6-10 mm long, 7.5-15 mm diameter, flared 3-3.8 mm above the base of the tube; petals 7-11 mm long, 4-7 mm wide, with rounded-triangular, apiculate lobes, glabrous except for hairs on the outside of the midpetaline band for 2-3 mm from the apex. Stamens 5, unequal; filaments affixed to the corolla tube for 1.5-2.5 mm from the base, free for 1.6-3.5 mm, with low tubercles from 0.5 mm above the base of the corolla and extending for 2-3.5 mm; anthers oblong to ovate-oblong, 0.8-1.5 mm long, 0.55-0.85 mm wide, apex obtuse, base sagittate, basal lobes 0.15-0.4 mm long. Ovary ovoid, 1-1.3 mm long, on an undulate disk 0.25-0.4 mm high, glabrous; style 2.5-4 mm long, with cylindrical, slightly flattened, obtuse stigmas, 1.4-2.2 mm long.
Fruits:
Capsule globular, 4-5.5 mm long and diameter, glabrous.
Habit:
Perennial with trailing and mainly twining stems; stems terete often ribbed, moderately to sparsely hairy, glabrescent, hairs crisped-appressed, mainly 0.2-0.35 mm long, rarely longer to 0.7 mm and more loosely appressed to ascending. Leaves may or may not vary in shape from base to tip of the stem (Fig. 3C).
Inflorescences:
Inflorescence solitary, axillary, bracteolate, a one-sided dichasium with 1-2 Flowers, or occasionally with 2 Inflorescences per axil; peduncle terete, wiry, 7-55 mm long, moderately to sparsely hairy, hairs crisped-appressed, 0.15-0.3 mm long; bracteoles opposite to subopposite, occasionally alternate, linear to subulate, 1-2 mm long, 0.35-0.5 mm wide, apex acute, with or without cilia, ± glabrous or very sparsely hairy on the back; pedicel 3-12 mm long, recurved at Fruiting, hairs as for peduncle, sometimes denser.
Infraspecific Characters:

Throughout central Queensland, populations of C. graminetinus tend to have hastate Leaves, ± glabrous sepals and crisped appressed hairs though plants with Leaves bearing prominent ascending lobes are found. Similar populations are found through the north western plains of New South Wales with the presence of ascending lobes on Leaves becoming more common. However in the north western slopes region of that state, some populations, such as Moore 9108 (CANB) have many spreading hairs on Leaves, stems and sepals. Aside from this character, the Leaves are often deeply divided with well developed ascending lobes. Two specimens Hoskings 1608 and 1681 (NSW) from the same population in Oxley Park, Tamworth are revealing. Hoskings 1608 collected in October 1998 features typical short crisped appressed hairs and ± glabrous sepals in contrast to the specimen collected in February 1999 which bears moderately dense spreading hairs on Leaves and sepals similar to those in Moore 9108. A specimen collected by J. Crawford from near Bingera (CBG12272) contains two separate branches, each branch representing the two different forms described above. The specimen, Portenters & Benson 9405019, was collected at a distance from the main area of distribution of this species. It has longer hairs, longer bracteoles, much hairier sepals, commonly 2 Inflorescences per axil and larger Seeds than do the other specimens. Wilson 1470 also has large Seeds but it otherwise agrees morphologically with specimens of C. graminetinus from Queensland.

Phylogeny and infrageneric relationships:

C. graminetinus
appears most closely related to C.
erubescens with its similar crisped appressed hairs, and its tendency for
the stems and peduncles to be slightly ribbed. Its Seeds have a similar surface pattern and the Inflorescence tends to be a one-sided dichasium with 1 or 2 Flowers. C. erubescens grows in
moister Eucalyptus forests and on the
edges of rainforest whereas C. graminetinus is found in grasslands and
marginal brigalow woodlands on heavy clay soils in sub-humid to arid areas.
Plants with hastate-sagittate Leaves resemble those of C. remotus. However, C. graminetinus has smaller and less
hairy sepals, smaller Flowers and the
Seeds are quite different in size,
shape and surface pattern.

Johnson, R.W.
General comments:

Stictocardia queenslandica resembles S. discolor Ooststr., based on the description given by Ooststroom (1943), which is known only from Timor. Both S. queenslandica and S. discolor have shorter sepals and corollas than S. tiliifolia. However S. discolor appears to have shorter sepals and longer and more slender peduncles and pedicels than S. queenslandica. In addition, S. discolor is characterised by a red coloration on the lower leaf surface.
