212 ON SOUTH-AMEEICAJSr APOCTNACE^. 



stricted at the mouth ; segments oval, undulate, 3 lines long ; disk of 5 oblong lobes, 

 longer than the 2 ovaries ; foUicles 2, more than a foot long, subtorulose, sometimes 

 conjoined at the apex. 



This plant,, from its habit, bifid raceme, from the tube of its corolla constricted below 

 the mouth, its disk, and its foUicles conjoined at the apex, agrees with Temnadenia, and 

 seems near T. secundiflora.

icon, ined.) : non vidi. 



A climbing species with fl.exible, terete, pilose branches ; leaves ovate, acuminate, cor- 

 date at the base, ciliate, pilose, 3 in. long, 18-20 lines broad, on petioles 3 lines long ; 

 racemes axillary, shorter than the leaves, on a simple pilose peduncle bearing several 

 alternate flowers spicately disposed on pedicels 3 lines long, supported by lanceolate 

 bracteoles 1 line long ; sepals lanceolate, acuminate, 3 lines long i corolla yeUow ; tube 

 cylindrical, 8 lines long, narrowed a little below the middle, smooth in the mouth ; seg- 

 ments ovate, acute, 3 lines long and broad ; anthers conniving in a cone in the middle 

 of the tube ; style pilose ; stigma bilobed; disk of 5 free linear lobes. 



This plant bears aU the characters of Temnadenia, and appears to be near T. secundi- 

 flora and T. glaucescens from the same country.

Gardner's specimen from Penedo agrees well with Lindley's drawing. It is a handsome 

 scandent plant, with flexuose puberulous branches, and axils 3 in. apart ; leaves ovate, 

 plicate and obsoletely cordate at the base, mucronately acute, velutinous on both sides, 

 3-3i in. long, l|-2 in. broad, on pubescent petioles 3 lines longj raceme lateral, 

 pubescent, on a suddenly deflexed peduncle bare for the length of 1 in., then.ce densely 

 many-flowered on pedicels 4-6 lines long; sepals acuminate, 2-3 lines lon^, with 5 inner 

 lanceolate scales at the base of each ; corolla ^ lines long, rose-cc^oured, with 5 stel- 

 lular, yellow, oblong patches in the mouth ; tube glabrous, constricted a little below the 

 middle for 6 lines, 14 lines long ; segments rhomboidally dolabriform, 6 lines long, 9 lines 

 broad, rotate ; stamens inserted at the contraction of the tube ; anthers coherent, acumi- 

 nate, pilose dorsally, biaristate at the base ; disk partly cleft into 5 oblong emarginate 

 lobes, nearly as long as the 2 ovate ovaries.

 non vidi. 



Muller wrongly regarded this plant as identical with Dipladenia saponaricB, A. DC. ; 

 but it cannot belong that genus, as its disk shows. It has a short erect stem, with 

 approximate leaves, which are oblong-lanceolate, contracted towards the base,, acuminate,
