LXXXY. CONVOLVULACEjE. 
[Poly met ia . 
campanulate, slightly silky-pubescent outside. Anthers rather long. Stigmatie 
lobes about 0. Capsule shorter than the calyx. Seeds pubescent or silky-villous 
(glabrous according to R. Brown). — Chois, in DC. Prod. ix. 432 ; Endl. Iconogr. 
t. 07. 
Halt.: Keppel Bay, R. Brown, Tliozet ; Rockhampton, O'Shanesy ; Gracemere, Bowman; 
More ton Bay, C. Stuart. 
Some of the narrow-leaved specimens might very well, without close examination, he mistaken 
for so ne varieties of Convolvulus erubescens. The outer sepals, although variable in breadth, 
are. however, always broader than in the latter species, independently of the generic character. —

4. P. ambigua (ambiguous), R. Br. Broil. 488; Benth. FI. Austr. iv. 433. 
An annual (or sometimes perennial ?), with long, slender, creeping or trailing 
stems, occasionally rooting at the lower nodes and sometimes shortly twining at 
the extremities. Leaves petiolate, ovate or oblong, obtuse, often mucronate, 
cordate at the base, usually rugose, glabrous, sparingly pubescent or rarely 
villous above, more or less villous or silky-hairy underneath, mostly about lin. 
long, but variable in size. Peduncles usually longer than the petioles, bearing 
l to 3 flowers with minute bracts at the base of the pedicels, and usually 2 small 
bracteoles on the pedicels. Sepals nearly equal, acuminate, about 3 lines long. 
Corolla not twice as long, very open. Stigmatie branches 4 to 6. Capsule 
nearly as long as the calyx. Seeds glabrous or very minutely hoary-pubescent. — 
Chois, in DC. Prod. ix. 432. 
Hub.: Islands of the Gulf of Carpentaria, R. Brown : Thirsty Sound, R. Brown : also in other 
northern localities. 
5. P. pusilla (weak), 72. Br. Prod. 488 ; Benth. FI. Austr. iv. 434. This 
may be another small slender form of P. ambigua, glabrous or slightly pubescent. 
Stems almost filiform, prostrate or twining. Leaves on slender petioles, from 
cordate-ovate obtuse or retuse and under lin. long to linear and then entire or 
hastate at the base. Peduncles 1 -flowered, with minute bracts at a distance from 
the flower. Sepals nearly equal, lanceolate, acuminate, about 2 lines long. 
Corolla about twice as long, very open. Stigmatie branches usually 4. — Chois, 
in DC. Prod. ix. 432. 
Hab.: Broadsound , R. Brown ; also from Bowman’s collection, with short ovate leaves as in 
Brown’s specimens ; Rockhampton, O'Shanesy , and Keppel Bay and Fitzroy River, Tliozet, with 
linear leaves. 
9. EVOLVULUS, Linn. 
(Not twining.) 
Corolla campanulate or tubular at the base, the limb 5-angled or 5-lobed. 
Ovary 2-celled, with 2 ovules in each cell. Styles 2. filiform, distinct from the 
base, each divided into 2 branches; stigmas linear, terminating each branch. 
Fruit a capsule, with 4 seeds or fewer by abortion.— -Herbs, not twining, annual 
or with a short perennial stock. Leaves entire, usually small. Flowers small, 
on axillary peduncles or in terminal spikes or racemes. 
A considerable tropical American genus, of which one or two species are spread also over the 
warmer regions of the Old World. The only Australian species is the one most common 
over the whole area. — Benth. 
1. E. alsinoides (Alsine-like), Linn.; Chois, in DC. Prod. ix. 447 ; 
Benth. FI. Austr. iv. 437. A perennial, with a short almost woody stock, but 
often flowering the first year so as to appear annual, with numerous slender 
prostrate or erect stems, Gin. to 1ft. long, the whole plant more or less silky- 
hairy. Leaves usually oblong or lanceolate, sessile or nearly so, 3 to 12 lines 
long, but varying from ovate to almost linear, obtuse or acute. Flowers small, 
pale-blue or white, 1 to 3 together on slender axillary peduncles mostly longer
