pale rose colour, or reddish purple, often rather small, somewhat funnel- 
shaped, with a regular border of 5 lobes, 2 of which are sometimes 
smaller; the filaments are slender, arch towards each other in pairs, 
seldom extend beyond the middle of the corolla, the anther-lobes being 
greatly divaricated. The capsule is long, linear, very compressed, 
having 2 flat coriaceous valves with tumid edges, parallel to a thin dis- 
sepiment, from which a filiform replum separates on both edges, and 
along the margins of which the imbricated seeds are 1-serially affixed ; 
the seeds are linear-oblong, with a broad opaque-winged margin, the 
extremities of which are diaphanous. The inflorescence is in long 
terminal panicles. 
From Arrabidea I have separated some of the species, and have 
associated with them some undescribed plants, which form a very dis- 
tinct genus, to which the name Tynanthus bas been given, on account 
of their small flowers. They are climbing plants, with the habit of 
smallest known among Hubignoniee: the calyx is small, turbinate, 
having an entire margin, with 5 long setaceous teeth, as in Cuspidaria, 
the corolla contracted within the calyx, swells suddenly, and is arcuated 
into a broadly ventricose tube, narrowing agaiu at its mouth, which is 
obliquely ringent, with a bilabiate border, the upper lip being erect, 
eoncave, often galeated, aud emarginated at the apex into 2 short 
rounded lobes which cover the stamens, the lower lip being deeply cleft 
into 3 obtuse reflected lobes; the didynamous stamens, in arching 
pairs, are far exserted, the anther-lobes being extremely divaricated, 
and curved upwards; the ovary is generally pulverulent, and seated on 
a pulvinate disk: the capsule and seeds resemble those of Arrabidaea.

This species is found in all the South-Western Provinces of Brazil. 
It is a climbing plant, with cirrhosely conjugate or 3-foliolate leaves,
