34 XCV. ASCLEPIADEX. (J. D. Hooker.) | [Gongronema. 
Maracca (? Finlayson), Griffith, Maingay (Kew Distrib, 1113). 
Leaves 3-6 by 1-2 in., firmly membranous; nerves 5-6 pairs, arched; petiole 
)- in. Cymes small; pedicels very unequal. Sepals small, oblong. Corolla j in. 
diam., lobes spreading. Coronal-scales broad, recurved, apparently confluent with 
the anther-base. Anther-tips large, exserted. Follicles 6 by } in., gently curved 
from base to tip, smooth. Seeds 4 in. oblong, wing broad recurved.— Finlayson's 
specimens in Herb. Wallich have no locality given. 
3. G. ventricosum, Hook. f.; quite glabrous, leaves coriaceous ovate 
or ovate-lanceolate obtusely caudate-acuminate, cymes subsessile few-íld., 
corolla-tube glabrous within, lobes as long linear with recurved margins. 
Kuasa Mrs. (Herb. Calcutta). 
Leaves 3 by 1-1} in.; nerves 2-3 pairs, very prominent beneath, strongly inarch- 
ing far within the margin; petiole stout, 4-3 in. Flowers very shortly pedicelled. 
Sepals very small. Corolla } in. long. Coronal-scales broad, recurved. Pollen-masses 
smaller than the corpuscle.—In form of corolla this a good deal resembles Gymnema 
Thomsoni. I have seen only a solitary indifferent specimen of this plant. 
G.? Fiwravsowm, Dene. in DC. Prodr. viii. 625 (Gymnema Finlaysonii, Wight 
Contrib. 46 ; Wall. Cat.), is probably, like most of Finlayson’s plants, from Siam. It is 
glabrous with ovate-cordate leaves, and has peduncled cymes of large flowers 4—} in. 
diam. The pollen-masses have long spiral pedicels. 
32. MARSDENIA, Br. 
Twining, rarely erect, shrubs or undershrubs. Leaves opposite. Cymes 
umbelliform, simple or branched, terminal or axillary ; flowers medium-sized 
or small Calyx 5-partite. Corolla campanulate or urceolate or salver-shaped, 
lobes narrow or broad, overlapping to the right.  Coronal scales b, usually 
subulate flattened (or 0), adnate to the anthers dorsally, erect. Column short; 
anthers with an inflexed tip; pollen-masses pedicelled, oblong or ovoid, waxy; 
erect. Stigma flat convex or beaked, sometimes very long. Follicles lanceolate 
or poniard-shaped. Seeds comose.— D1sTRIB. Species about 50 ; chiefly tropical 
or subtropical, with one S. European. 
A heterogeneous assemblage. amongst which perhaps M. tinctoria, eriocarpa, and 
thyrsoidea should form one natural genus, and the remainder a second. M. thyrsoidea 
is very remarkable in wanting the coronal scales. 
Sect. I. Bumarsdenia. Flowers small. Corolla cylindric, shortly 
5-cleft, mouth closed with a brush of short hairs. Column minute ; anther- 
tips and coronal scales very short. Stigma truncate. 
l. M. tinctoria, Bir. in Mem. Wern. Soc. i. 30; nearly glabrous, leaves 
ovate or cordate acuminate or caudate, flowers in dense thyrsoid or rounded 
panicles, coronal scales subulate longer and narrower than the anther-tip, 
ollicles finely pubescent. Wight Contrib. 40, and Ic. t. 589; Wall. Cat. 81731 |
