This is a prostrate plant, with much the habit of a Nolana, its 
branches measuring a foot and upwards. Its petioles and pedi- 
cels are erect, and therefore are all somewhat secund: I have not 
seen any cauline leaves, but the floral leaves are much smaller, 
greatly narrower, and upon a shorter petiole than in the follow- 
ing species ; the pedicels are 2 to 4: lies long, the calyx is 3 lines 
long, and 1 line diameter, swelling afterwards to a length of 7 
lines and a diameter of 5 lines: the corolla is 15 or 16 lines long, 
and 10 to 13 lines broad across the border ; it is pubescent out- 
side, is persistent, and on withering, coils up in a spiral form, 
when the peduncle increases to a length of 9 lines and becomes 
suddenly reflexed. The berry is 4 lines in diameter, enclosed 
within the eularged vesiciform calyx.

Trans. xx. p. 203 ;—subpubescens, foliis ovatis, acutis, basi 
inzequalibus, cordato-auriculatis, et i petiolum angustatis, ir- 
regulariter sinuato-angulatis, angulis subobtusis, 83-5-nerviis, 
crasso-coriaceis, utrinque pilis brevibus rigidiusculis articulatis 
conspersis, longissime petiolatis ; floribus solitarius vel geminis, 
lateralibus, corolla sub-violacea extus puberula, limbo vix expla- 
nato, staminibus corolla brevioribus.—Ins. Gallapagos, v. s. in 
herb. Hook. (Charles et Albemarle Islands, Darwin.) 
This plant possesses a habit similar to that of the former spe- 
cies. The branching stems of woody texture are fistulose, smooth 
and terete. The leaves are from 2} to 3 inches long, 2 to 23 
inches broad, on a channeled petiole 5 inches long, that is nearly 
rectangular with the stem : they are almost smooth, or sparsely 
covered with very short rigid hairs: the peduncles are slender,
