112 ON SOUTH-AMEEICAJSr APOCTNACEa;. 



The specific name is changed to surrecta, that it may no longer be confounded with 

 the Echites suberecta of Jacquin (non Sw.). 



A drawing of it, with its floral analysis, is given in Plate XV. b.

A very slender, branching, climbing plant, growing to a height of 10 feet, with fili- 

 form, terete, pubescent, lactescent branchlets; leaves ovate-oblong, rounded or sub- 

 cordate at the base, acute at the summit, entire, rigidly chartaceous, glabrous above, 

 nerved and reticulately veined, pale ferruginous beneath, and scabridly pubescent, those 

 of early growth narrowly linear and 3 in. long, those of permanent production 1-1 ^ in. 

 long, 6 lines broad, on short pubescent petioles ; panicles axillary, subracemose, shorter 

 or longer than the leaves, on bifid peduncles, each branch bearing few large odoriferous 

 yellow flowers; sepals subulately linear, erect, subhirtous, 4 lines long; tube of corolla 



1 in. long, cylindrical below for a length shorter than the sepals, swelling above, and 

 spreading to a breadth of 5 lines in the mouth, which is villous inside and subpenta- 

 gonous ; segments large, obliquely inequilateral, undulated on the margin, 12 lines long, 

 10 lines broad ; stamens seated at the contraction of the tube, enclosed ; anthers linear, 

 with long slender apical appendages, spirally twisted together ; disk of 5 roundish yellow 

 lobes, embracing the 2 ovaries ; style short ; clavuncle incrassate, 5-lobed ; stigmata 2, 

 globose. 



This species evidently belongs to Chariomma (not to Skytanthus), on account of its in- 

 florescence with large yellow flowers, the position of its stamens, and the presence of a 

 conspicuous disk. 



3. Chariomma mucronulata, nob. In ins. San Thomas, v. s. in herb. Mm. Brit, ex loo. cit. (Rhyons, 

 sub Echites erecta) . 



A species near C. Domingensis, differing in the size and shape of its leaves and in its 

 smaller flowers. It has rather slender terete branches, with axils IJ in. apart ; leaves 

 opposite, oblong, narrower towards the roundish base, broader and rounded at the mu- 

 cronulate summit, chartaceous, with subcrenulate revolute margias, pale green above, very 

 opake, with about 8 pairs of scarcely prominulent fine ascending nerves, opake and sub- 

 ochraceous beneath, with a flattened midrib, promiaulent nerves, and finely reticulated 

 veias, 2-2 J in. long, |— 1 in. broad, on channelled petioles 2 lines long ; inflorescence 

 axillary, as long as the leaves, on a bifid peduncle, each branch bearing 3 or 4 flowers 

 on finely hirsutulous pedicels 3 liues long; sepals linear, acuminate, membranaceous, 

 hirsutely pilose outside, 3 lines long, \ line broad, pilose along the nerve within, with 



2 or 3 very minute internal scales ; tube of corolla 7 lines long, stoutish, narrower at its 

 base for 2\ lines, spreading above to a breadth of 6 lines ; segments dolabriform, 6 lines 

 long, and as broad, acute at the sinister angle, and dextrorsely convolute, subvillous 

 outside, as well as the tube ; stamens inserted iu the constriction of the tube, and alto- 

 gether included ; filaments pilose ; anthers ovate, shortly bifurcate at the base, expanded
