 fructiferous peduncle 6 lines long, the pedicels 3 lines long ; the persistent sepals 1^ line 

 long; 2 terete follicles acute at both ends, very divaricate, ' subreflected, 4| in. long,

 non vidi. 



A scandent plant with oval mucronulate leaves, obsoletely pubescent above, rufes- 

 cently tomentellous beneath, IJ-BJ in. long, 10-18 lines broad, on petioles 2-3 lines 

 long ; peduncle of the axillary inflorescence longer than the leaves, often bearing 2 

 flowers on pedicels 2-3 lines long; sepals linear-subulate, IJ line long, reflexed; corolla 

 rose-coloured ; contracted portion of tube 6 lines long, inflated portion 20 lines long, 

 8 lines broad, subcylindrical ; segments broad; stamens inserted in a pilose ring at 

 the sudden contraction of the tube ; disk of 5 free, erect lobes, as long as the 2 ovaries ; 

 follicles terete, 4 in. long. 



Muller states that the sepals have no inner basal scales.

A species seen alone by Desvaux, and known to us only by his imperfect description. 

 De Candolle did not see it ; and the determinations of Muller and Grisebach are mere 

 guesses, founded on a chance observation in the ' Prodromus.' Prom Desvaux's account 

 the characters of the inflorescence and the form of the corolla are certainly more in 

 accord with those of Rhabdadenia than of Urechites. It is an erect shrub, with pubes- 

 cent branches; the leaves are obovate, submucronate, glabrous, with distant oblique 

 nerves ; panicle on a long peduncle supporting few flowers ; sepals subulate, pilose ; 

 tube of corolla barbately pilose, narrow below for the length of the calyx, thence swelling 

 upwards.

Apparently a scandent plant from Willdenow's herbarium ; leaves elliptic-oblong, sub- 

 cordate at the base, obtuse at the summit, lucid above ; inflorescence a solitary flower, on 

 an elongated pedicel, as in the Echites madida, Veil. Icon. iii. tab. 42, and as sometimes 

 occurs in H. Pohlii.
