ON SOUTH-AMERICAJS" APOCTNACE^. 217 



bifid peduncle ; sepals oblong, erect, concave ; tube of corolla cylindrical, longer than 

 the calyx, with a prominent ring in the mouth, concave beneath, apparently without 

 appendages; segments obliquely roundish, emarginate, rotate; disk of 6 small ovate 

 lobes. 



From its bifid peduncle and flowers without faucial appendages, it probably belongs 

 to this group.

A climbing species, with scabridulous branches, the axils 5^ in. apart ; leaves opposite, 

 elliptic-obovate, obtuse at the base, subacute at the reflexed summit, nerves divergent, 

 2^3 in. long, l|-lf in. broad, on patent slender petioles 3 lines long ; raceme lateral, 

 not quite as long as the leaves ; peduncle bare for 1 in., bearing above 12-16 subalter- 

 nate flowers on reflexed pedicels 8 lines long ; sepals acuminate, reflexed at the apex, 

 2 lines long ; corolla greenish-yellow, with a white cylindrical tube, broader at its base, 

 9 lines long, pentagonal above, and somewhat thickened in the mouth, without any 

 apparent appendages ; segments obovate, obliquely truncate,. 4 lines long ; stamens in- 

 serted above the inflated portion of the tube on a pilose ring ; anthers lanceolately 

 acuminate, hastate at the base, cohering in a cone, which fills the upper portion of the 

 tube ;. disk 5-lobed, as long as the ovaries. 



De Candolle considered this species quite foreign to Frestonia, and not conformable 

 with SoBmadictyon ; the flowers were regarded by him as agreeing with those of his 

 Echites cordata [Angadenia nitida, antfe, p. 177). 



MiTOZUS*. 



An extensive ' natural group of plants, one of the most uniform in its characters 

 among the JEchiteee, easily recognizable by their extremely slender branchlets. They 

 disagree utterly with Anisolobus and Ambly anther a, to which some of the species have 

 been referred by Miiller. The Echites funiformis of Velloz may be regarded as the 

 type. The almost filiform branchlets are dilated at the somewhat remote nodes, and 

 there furnished with 2 small caducous stipules ; the leaves are opposite, generally rather 

 small, glabrous, oblong, often cordate at the base, pointed at the summit, upon short, 

 slender petioles ; the inflorescence is lateral, upon a long or shorter peduncle, bearing 

 several alternate flowers on minutely bracteolate pedicels ; calyx small; corolla salver- 

 shaped, rather small or of moderate size, with dextrorse convolution. Its chief peculiarity 

 is its disk, which is tubular, submembranaceous, 5-grooved, entire on the margin or 

 arched between the grooves, quite or nearly concealing 2 free ovaries. The fruit consists 

 of 2 long, very slender follicles, smooth, often torulose, either free or conjoined at the 

 apex ; seeds with a simple sericeous coma. 



MiTOZus, nob. Calyx parvus; sepala 5, acuta ant obtusa. Corolla mediocris ; tubus infra medium cylin- 

 dricus, superne amplior ; segmenta oblique ovata, tubo dimidio breviora, in sestivatione dextrorsum 



* From jufros {filvm), o^os (ramus), from its funiform brandies.
