Species singula adhuc nota insulae Luzon indigena. 
The affinity 6f this genus lies with the plants, that have been 
united by Schumann under the name of Glossonematinae, of which 
however some are surely belonging to the Oxypetalinae, while others are 
better placed into the Gonolobinae. The remaining genera (no. 47— 52) 
should better be united with the Asclepiadinae. In ‚the structur of the 
flowers our plant belongs to these but stands quite isolated by its habit.

— Inter affines foliis subdistichis insignis. — Arbor mediocris (Gibert) 
novellis glaberrimis. Rami florigeri graciles, internodiis saepius petiolos 
5—10 mm longos vix excedentibus. Folia petiolata, subcoriacea, in eodem 
ramo florigero inferiora et superiora quam intermedia saepius minora; lamina 
anguste lanceolata, oblonga, oblanceolata vel interdum fere elliptica, 
absque petiolo 2—8 cm longa, 1—2 em lata, apice glandula minuta in- 
structa vel eglandulosa, basi cuneata, margine obscure crenulata, raris- 
sime hine inde glandulis 1—3 praedita, venis inconspicuis; petiolus 
rigidus, glandulis superioribus conicis erectis distincte porosis; stipulae 
triangulares, circiter 2 mm longae, persistentes. Spicae subterminales, 
sessiles, rigidae, densiflorae, 4—8 cm longae, masculae vel androgynae. 
Flores masculi sub quaque bractea circiter 8; bractea paucidenticulata, 
glandulis orbicularibus ellipticis imbricatis, Perianthium florum femineo- 
rum ovoideum, tridentatum, dentibus vix acutis.  Stylorum columna 
distincte exserta; styli rami 3, recurvi. Capsula immatura tantum visa, 
globosa, cireiter 8 mm diametro. — Uruguay: Monte Video; banks of 
rivers, Gibert, 8, 171, 181. — Of this very distinct looking species I 
have only seen Giberts specimens, which were collected on three diffe-
