135. SmENE HETERODONTA, sp. nov. 
Glanduloso-pubescens. Caules diffusi vel a basi arcuata 
adscendentes, simplices vel infra medium dichotomo-bifurcati, 
ramo laterali altero dichotomie deficiente. Folia inferiora 
ovato-spathulata, in petiolum attenuata, apice rotundata obtu- 
sissima mucronulato-apiculata, hispido-ciliata, superiora angus- 
tiora sessilia. Flores solitarii. Calyx tubuloso-clavatus, hirtulo- 
pubescens, basi truncatus, fructifer dilatato-clavatus infra 
capsulam attenuatus vix constrictus, nervis rubellis vel 
viridibus sparse anastomosantibus, dentibus ovato - triangu- 
laribus, aliis acutis aliis obtusis, albo-marginatis, ciliatis. 
Petala biloba, lobis obovato-oblongis, unguibus exsertis, inferne 
ciliatulis, appendicibus bipartitis segmentis ovato-lanceolatis 
acutis. Capsula oblonga carpophorum pubescens ter superans. 
Semina compressa, faciebas auriculiformi-concaviuscula, dorso 
acute canaliculata, granulata. (Herb. Kew., Atlas Expedition 
(1888), coll. J. Thomson.) 
Speciei sequenti valde affinis, sed insigniter diversa. Heecce 
differt,—in bifurcatione infra caulis medium, foliis apice magis 
rotundatis, calyce basi truncato infra capsulam attenuato, 
petalis bilobis nec bipartitis, appendicibus bipartitis, carpophoro 
pubescente breviore, seminibus dorso acute canaliculatis. 
The name is derived from the dissimilar calyx-teeth.
