Suffrutex humilis. Rami lignosi, cortice griseo-luteo tecti, fere eylindriei (leviter 
striati), subnitidi, pilis brevibus (1: 3) rectis obtusis papilliformibus patentibus remo- 
tissime obsiti, fasciculos foliorum edentes et in racemos abeuntes. Folia crassa, carnoso- 
coriacea, linearia acuta integerrima, plerumque superne canaliculata, basi non attenuata 
sessilia, pilis papilliformibus minutissime pubescentia. lores pro genere maximi; ala- 
bastra ovata, basi rotundata; sepala anguste ovata, angustissime albo-marginata, mediana 
apicem versus leviter carinata et quasi corniculata; petala calyci subaequilonga, linearia 
vel lineari-subulata vel anguste rhombica subacuta; stamina 2 -4- 4 antheris fere linearibus 
post anthesin extrorsum curvatis; glandulae 6 extra stamina sitae contiguae (quasi leviter 
confluentes), valde conspicuae subglobosae; ovarium oblongo-obovatum acute emarginatum, 
stylo longo filiformi apice attenuato (stigmate capitulato), septi fere ?/4 longitudine adae- 
quante terminatum. ARacemi fructiferi satis breves, laxiusculi, axi leviter anguloso-sulcato 
minutissime pubescente, pedicellis crassiusculis suleatis fere rectis patulis, silienlae sub- 
aequilongis. Silicula pro genere maxima, anguste elliptica (1 : 2), plana, utrinque attenuata, 
apice haud profunde (ad '/s—!/s longitudinis septi) et satis acute emarginata, lobulis 
alaribus in utroque latere emarginaturae porrectis obtusiusculis latitudini ipsorum sub- 
aequilongis, stylo filiformi quam emarginatura fere triplo longiore; valvulae carinatae, 
a medio ad apicem alatae, nitidae, vix reticulatae; replum angustum, parte quarta in- 
feriore basin versus sensim dilatatum; septum lanceolatum, in stylum acuminatum, 
marginem versus transverse rugosum. Semina late ovoldea, modice compressa, fere 
laevia, margine exteriore anguste alata, fusca; embryo?
