Marsdenaa. | XCV. ASCLEPIADEZ. (J. D. Hooker.) 35 
A tall climber; stem stout, smooth, glabrous or finely pubescent, as are the 
petioles, sometimes the leaves below, and cymes. Leaves 3-9 by 1-3 in., nerves 
spreading, glandular above at the petiole; petiole 1-2 in. Cymes short- or long- 
peduncled, rounded and 3-1 in. diam. or elongate 3-6 in. long, thyrsoid, formed of 
interrupted clusters; pedicels short. Sepals ovate, pubescent. Corolla 4, in. long, 
yellow, fleshy, glabrous externally ; tube with deflexed hairs within. Follicles 3 in. 
long, $ in. diam., narrowed at the base. Seeds narrowly ovoid, 4-4 in. long.—In the 
absence of any description or figure of the follicles, or of authentic specimens in fruit 
of the Sumatran plant on which the genus was founded, I am in doubt whether this 
or the following is the true M. tinctoria. The flowers are often deformed, very large, 
and the column is often replaced by rudimentary leaves. Decaisne erroneously quotes 
Rheede’s Kada Kodi (Hort. Mal. ix. 72, t. 8) for this plant. 
2. M. eriocarpa, Hook. f.; foliage of M. tinctoria, follicles shorter 
broader turgid at the base softly villous with long spreading hairs, seeds 
broadly ovate. 
SıLnerT, Herb. Wallich (Asclep. 145 A). Assam, Masters. 
Wallich on the ticket of his specimen (which has no Catalogue number) says of 
this “ Marsdenia, tinctorie affinis, sed differt ; E. Sylhet, introd. in H.B. Calc. Feb. 
1840." Brandis describes the pod of M. tinctoria as ** covered with long soft, hairs," 
whence he probably has assumed that this is referable to M. tinctoria, and, if so, the 
plant I have described under that name must be named afresh. A reference to 
Marsden's Sumatran plant can alone solve the difficulty. 
Secr. II. Macrocentrum. Flowers larger. Corolla subcampanulate ; tube 
short, globose or subcylindric; lobes large, fleshy, spreading, and throat glabrous 
or villous. Staminal column large, filling the tube; coronal scales usually 
large, often exceeding the anther-tip. 
* Stigma not extended beyond the anthers,

and cymes finely pubescent or tomentose, leaves ovate-cordate acuminate, 
cymes corymbose, corolla-lobes pubescent without villous within, coronal scales 
ender subulate far exceeding the short anther-tips. Brand. For. Fl. 333;

coronal scales coriaceous subulate hardly exceeding the ovate anther-tip.
