Gen. Char. (Vide supra, Tas. 4702.) 
Dipapenta Boliviensis ; scandens, glaberrima, foliis petiolatis acuminatis 
basi acutis, stipulis 0, calycis lobis brevibus ovatis acuminatis, pedicellis 
tortis, corolla alba tubo cylindrico fauce elongato-cylindrico, ore flavo non 
constricto, limbi patentis lobis late ovatis obtuse acuminatis, glandulis 
ad basin sepalorum lobulatis, squamis hypogynis semi-orbicularibus. 
The genus Dipladenia has hitherto been supposed to be 
confined to the east coast of America, ranging from Trinidad 
to South Brazil; hence the discovery of the present species in 
Bolivia by Mr. Pearce, late collector to Messrs. Veitch and 
Sons, is a most interesting one. As a species, it approaches 
very near indeed to D. urophylla Hook. (Tab. nost. 4414) 
from the Organ mountains of Brazil, but differs in the shorter 
apices to the leaves, the much narrower throat of the corolla, 
and white flowers. It is a very beautiful plant, well deserving 
of cultivation, and flowered for the first time in June, 1868, 
in Messrs. Veitch’s establishment. 
Descr. Everywhere perfectly glabrous. Stems slender, 
terete, twining. eaves petioled, two to three and a half 
inches long, oblong or narrow oblong, narrowed into an obtuse 
acumen, acute at the base, bright green and glossy above, 
pale beneath, stipular glands none. acemes subterminal or 
axillary, three to four-flowered; peduncles short. green ; 
bracts minute, at the base of the short stout twisted pedicels. 
Calye-lobes short, ovate, acuminate, green, one quarter of an 
inch long. Glands at the base of the calyx-lobes short, lobulate. 
Corolla almost salver-shaped, the tube and throat being both 
of them narrow and slender ; tube cylindric, half an inch long ; 
faux about twice as long and half as broad again, golden 
JULY Ist, 1869.
