114 ON SOUTH-AMERICAN APOCYNACEX. 
stout petioles 3 lines long; terminal panicle sessile, trifidly branching from its base, 
each branch on a peduncle j-1 in. long, bearing 3 yellow flowers, on pedicels 3 lines 
long, supported by linear bracts; sepals acutely oblong, 6 lines long; tube of corolla 
23 in. long, narrowed below the middle, campanularly expanding above; segments 
rhomboidally dolabriform, 14 in. long and broad. There are indications in the rough 
drawing of the long setiform expansions of the anthers. According to Lunan, the leaves 
are poisonous and acrid, and the disk of 5 lobes tridentate at the apex. 
7. CHARIOMMA SCANDENS, nob.: Apocynum scandens flore nerii albo, Plum. Descr. Plants Amer. p. 82, 
tab. 96. In insul. S. Domingo et Martinico: non vidi. 
A lactescent, sarmentaceous shrub, with opposite cinereous branches 2 lines thick, 
with axils 44-54 in. apart; leaves opposite, oblong, gradually narrower towards the base 
and decurrent on the petiole, roundish above and suddenly terminating in a short 
mucronate point, entire, rigidly chartaceous, bright green above, with about 15 pairs of 
parallel patent arching nerves, darker beneath, 23-33 in. long, 13-13 in. broad, on 
petioles 5-6 lines long; raceme lateral, on a peduncle ¿-13 in. long, bearing on its 
summit 3-4 verticillate flowers, or more often a solitary flower by abortion; bracts 
short, linear; pedicels 6 lines long; sepals oblong, subacute, 3 lines long; tube of 
corolla 2 in. long, contracted below the middle, funnel-shaped above, of a reddish 
colour; segments white, dolabriform, uncinate at one angle, 12 lines long, 9 lines 
broad; follieles terete, parallel, erect, acute, 8 in. long, 1j line thiek, subconjoined at 
the apex; seeds many, clothed on their surface with dark reddish soft hairs. 
Althougn so little of the floral structure is known, it is manifest from its habit, its 
large handsome corolla like that of an oleander, with broad dolabriform segments 
uncinate on one angle, that it belongs to this genus, with which it agrees in the 
character of its follicles, as indicated by Swartz. The exserted appendages of the 
anthers are seen in Plumier's rough figure, by error 8 in number. It is a species evi- 
dently congeneric with his Apocynum scandens, last described. 
ELYTROPUS. 
A genus established in 1860, by Dr. Müller, upon the Echites pubescens, Hook. and 
Arn., a plant from Chile, and which comprises few species. These are mostly shrubs, 
with opposite, ovate or elliptic leaves, upon short petioles, and very short, few-flowered 
axillary panicles; they bear 2 compressed linear follicles, with several imbricated seeds, 
without any apical coma, which are much flattened, clothed above the middle with 
many ascending soft hairs, which extend far beyond the apex, and are peltately attached 
in the middle to intruding placentze. Each seed contains an embryo in thin albumen, 
with foliaceous cotyledons, and a terete radicle of the same length.
