I found this plant growing at Tejuca and in the Organ moun- 
tains: it is altogether glabrous: the stems are sarmentose, and 
in the younger branches the leaves grow in dense fascicles, which, 
as they fall off, leave them covered with crowded cicatrices, giving 
them an areolate r ugose appearance ; these terminate in a straight, 
angular, smooth stem, covered with a shining bark that readily 
peels off ; the axils here are from 13 to 2 inches apart, and each 
solitary petiole i is articulated in a projecting cup, from which a 
sharp ridge becomes decurrent on the stem below it ; the leaves 
are 43 inches long, 2 inches broad, on a channeled petiole 2 i to 
3 inch in length ; the peduncle is 7 ‘inch long ; the calyx 13 inch 
in length, 3 inch ‘diameter ; ; the corolla including the lobes, ‘at the 
period of opening, is 4 inches long, and when ‘the segments are 
coiled back, 23 inches long; the cylindrical portion of the tube, 
3 inch long, is included within the calyx, from which point it 
becomes gradually funnel-shaped, and a little below the mouth 
is somewhat EINE and about 1 inch in diameter, the lobes 
of the border bemg Linch i in length and 5 lines broad at base, 
these are marked ‘by aes parallel nerves which are ANeontinned
