174 ON SOUTH-AMEEICAN APOCTNACE^. 



glauco-velutinous beneath, 3^5^, in. long, 2^-3^ in. broad, on petioles 2-3 lines long ; 

 racemes axillary and terminal, opposite, about as long as tbe leaves, on a very slender 

 flexuous peduncle bare at tbe base for tbe lengtb of 1 in., bearing above 5 to 8 alternate, 

 rather distant flowers on slender pedicels 6-8 lines long, twisted, and bracteolate at the 

 base; sepals oblong, imbricate, 2 lines long; corolla hypocrateriform ; tube cylindrical, 

 slightly contracted in the middle, 1^ in. long ; segments rotate, dolabriform, 9 lines long, 

 4 lines broad; stamens seated a little above the middle of the tube, and reaching the 

 mouth, with 2 short divergent prongs at the base; disk urceolate, fleshy, with very numerous 

 fine denticulations on the margin, some few of them deeper than, the others, shorter than 

 the 2 conical, oblong, glabrous ovaries.

A species distinct from the preceding. It has stouter, flexuous branches, with axils 

 4 in. apart ; leaves ovate-oblong, deeply cordate at the base, rather obtuse and suddenly 

 mucronate at the summit, margins subrevolute, of a palish green above, but pubescent 

 on the midrib and nerves, of which there are 10 pairs divergent and prominulous, furnished 

 with transversely reticulate immersed reins, beneath very opake and yellowish glaucous 

 on the midrib and nerves, 3-6 in. long, lf-3|- in. broad, with a basal sinus 2-5 lines deep, 

 on glaucous channelled petioles 3-6 lines long ; racemes axiUary, opposite, on stoutish 

 peduncles naked at the base for 1^ in., bearing above about 8 opposite flowers on very 

 slender pedicels 7 lines long ; sepals ovate, subacute, 2|-3 lines long, each furnished with 

 2 bifid internal scales ; tube of corolla 11 lines long, narrowly cylindrical, contracted in 

 the middle; segments dolabriform, 8 lines long ; stamens seated in the contraction of the 

 tube ; anthers acuminate, with 2, somewhat divergent, basal prongs ; disk shortly cleft 

 into 5 or 10 striate, denticulate lobes, as long as the 2 glabrous ovaries. 



3. Angadexia sylvestris, nob. : Echites sylvestris, A. DC. I. c. p. 464 : Echites grandiflora, Stadelm. 



(non Meyer) Bot. Zeit. 1841, p. 49 : Odontadenia sylvestris, MiiU. (in parte) I. c. p. 117 (excl. tab. 

 35 A. fig. 3) . In Brasilia, Rio Japure in sylvis (Martins) : non vidi. 



This species is evidently not a true Odontadenia, but, like the O. hypoglauca of MiiUer, 

 belongs to this group. DeCandoUe described it from the Echites grandiflora of Stadelmeyer, 

 who xirongly confounded it with Meyer's plant of the same name from Guiana. The 

 plant seems to have been collected by Martins, near the river Japure, a region south of 

 the Rio Negro. Miiller united it with another plant collected- by Sagot in Guiana, which 

 is the Echites coriacea of Bentham, here described under the following species ; we must 

 therefore reject the specific character and the floral analysis of Miiller, and trust wholly 

 to that given by DeCandolle. Its branches are obtusely 4i-angled, and their axils remote; 

 the leaves are cuneately obovate, with a short, mucronate acumen, membranaceous, 

 marked beneath with prominent midrib and nerves and obliquely transverse veins, 5-8 

 in. long, 2-4 in. broad, on petioles less than 1 inch long ; panicles axillary, shorter than 

 the leaves, on peduncles often 3 in. long, bearing many flowers on pedicels 3 lines long,, 

 minutely bracteolate ; sepals obtusely ovate, 3 lines long, with inner trifid scales ; corolla 

 2^ in. long, yellowish red, its tube somewhat ventricose within the calyx, narrowly cylin-
