5. LEPISTEMON. Blame. 
(From the scale at base of each stamen.) 
Character of Ipomcea, but filaments dilated -at the base into 5 concave scales 
■which arch over the ovary. 
Species few; besides Queensland, met with in Africa and Asia. 
Pedicels much longer than the calyx. Leaves cordate-ovate 1 . L. urceolatus. 
Pedicels shorter than the calyx. Leaves hastate 2. L. I.vccr. 
1. L. urceolatus (jug-form), F. r. M. Syst. t vns. Austr. 1 J I. A tall twiner, 
softly villous, the hairs of the branches reflexed, those of thp foliage almost silky. 
Leaves petiolate, cordate-ovate, acuminate, entire. 3 to 4in. long. Flowers 
numerous, in dense almost sessile cymes or clusters, the pedicels much longer 
than the calyx. Sepals orbicular or broadly ovate, obtuse, hirsute, scarcely 
above 1 line long. Corolla-tube ovoid, inflated, contracted towards the throat, 
about Yin. long, the limb spreading, scarcely half as long as the tube. Stamens 
attached at base of corolla, the scales prominent. Anthers yellow. Capsule- 
globular. glabrous, about 3 lines diameter, 2-celled. Seeds 4, glabrous . — Ipomaa 
urceolata, R. Br, Prod. 485; Benth. FI. Austr. iv. 427 ; Convolvulus urceolatus, 
Spreng. Syst. i. 601. 
Haii Endeavour River, Banks and Solander : common in most of the tropical scrubs. 
2. L. Lucae (after Dr. Lucas), F. v. AI. in l ie. A at., October , 1885. Branchlets 
and leafstalks beset with appressed hairs. Leaves hastate, gradually narrowed 
into an acute apex, the sinus narrow, the lobes ending into a rather acute 
sometimes excised angle ; both sides of the leaves beset with appressed hairs, the 
under more so than the upper ; cymes almost forming umbels. Pedicels during 
;inthesis about as long as the peduncles, shorter than the flowers, appressed - 
hairy. Sepals ovate-orbicular, minute, many times shorter than the corolla. 
Stigma didymous : ovary and crenulated disk formed by the scales of filaments 
glabrous. 
Hal* : Given between the Endeavour River and Port Douglas. Dr. Lucas. 
G. CALYSTEGIA. R. Br. 
(From the calyx being covered by two bracts.) 
Sepals ovate or oblong, inner ones smaller. Corolla funnel-shaped or cam- 
panulate ; limb 5-plaited, subentire. Stamens included. Ovary 1 (imperfectly 
2) celled. 4-ovuled ; style filiform, stigmatic lobes 2, shortly oblong. Capsule 
globose, 1 -celled, normally 4-seeded. Seeds glabrous. Prostrate or twining 
herbs, glabrous or nearly so. Leaves entire or lobed. Peduncles 1 -flowered. 
Bracts 2 large, persistent, enclosing the calyx. Flowers usually large, white rose 
or violet. 
The -pec-ii - belong to warm and temperate regions of both hemispheres. 
Leaves hastate, acuminate. Braeteoles broadly cordate, almost orbicular. 
Calyx 2 lines. Corolla 9 lines long 1. C. marijinata _ 
Leaves cordate or hastate, acute or acuminate. Braeteoles ovate, acute, 
longer than the calyx. Sepals 4 to 5 lines. Corolla above 2in 2. C. sepiinn. 
Leaves fleshy, reniform or rounded, cordate, obtuse. Braeteoles ovate, very 
obtuse, shorter than the calyx. Sepals 4 to 6 lines. Corolla about liin. 
long 3. C. Soldo nella. 
1. C. marginata (margined), It. Hr. Prod. 488. A glabrous twiner. 
Leaves on rather long petioles, narrow-lanceolate or broad and triangular, 
hastate or sagittate, the basal auricles or lobes acute, diverging, and often lobed, 
the whole leaf usually 1Y to 2in. long, but when luxuriant twice as large. 
Peduncles rarely exceeding the petiole. Bracts very broadly cordate-ovate, from.
