mucronatis extus v^lutiuis intus glabiisj corolla cxtus hirsutissima intus glabra calyce duplo lojigiorCj 
ovario ^tIIoso. Cerro de Lancon, near the city of Panama; also collected about Panama by Cum- 
ing (no. 1158). ' . 
This species, having, like several other Convolvulacece, a milky juice, is closely allied to I. pycnocephala, 
Benth. (Bot. Sulph. p. 137), from -which hoTvever it is easily distinguished by its externally hirsute corolla. 
The petioles are generally more than an inch long ; the lamina of the leaves is from 2-2^ inches long, and 
about 1| inch broad. Tlie flowers look at first sight like those of Argyreia capitata, Chois. The peduncles 
are twice as long as the petioles. The bracts and sepals are of equal length. The corolla is 1 inch and 3 
lines long, and white ; the capsule is unknown.

L. ciliata, Linn., and Z. involucrata, Gr. Don, are so closely allied that it is very difficult to distinguish 
them, if they are indeed distinct species, or not mere forms, as Mr. Bentham supposes. However, the L. 
involucrata is said to have blue flowers ; the plant here noticed has pale yellow ones.
