Ser. 2, ante C. subuligeram Koehne). 
Icon: Koehne Atl. ined. t. 44 fig. 372. 
Fruticulus videtur; rami elongati recti, pilis brevissimis scabriusculi 
simul hispidi. Folia internodiis vix v. dimidio longiora, opposita, in peti- 
olum 2—5 mm longum attenuata, ovato-lanceolata (30—60 mm: 11—25 mm), 
sensim angustata v. subacuminata, supra strigoso-scabra et remote ad- 
presseque hispidula, subtus hirtello-strigosa et in nervis hispidula, mem- 
branacea, penninervia nervis utrinsecus circ, 7—9. Flores axillares, 
ramulo brevissimo pauci—A-floro axillari oppositi, quare inflorescentia 
(foliosa) composita; pedicelli 4—7 mm lg., medio vel supra medium pro- 
phylla parva ovata gerentes. Cayx (25—30 mm) brevissime calcarato- 
gibbus, leviter incurvus, crassiusculus, puberulus et dense hispidulus, 
coccineus faucis obliquae ventre viridis, intus supra stamina ventre lanatus, 
infra eadem glaberrimus; lobi breves ciliati; appendices lobis sub- 
longiores, plicato-patentes, hispiduli. Petala 6 minima, vix ultra 
| mm lg. inclusa, 2 dorsalia spathulata minutim ciliolata, 4 ventralia lineari- 
subulata. Stamina 44, ad tubi 4/; lineae rectae inserta; 5 episepala circ. 
1/4— 1/5 exserta filamentis 2 parce villosiusculis, 3 glabris; 4 episepala 
ventralia lobos fere aequantia filamentis villosiusculis, 9 dorsalia dimidio 
fere breviora sed vix inferius inserta. Ovarium glabrum valde obliquum in 
stylum valde deflexum triplo longiorem post anthesin ad 10 v. 42 mm ex- 
sertum glabrum abiens; discus subhorizontalis, 3-sulcus, 4-lobus, lobis 
2 mediis majoribus; ovula 20—26. Semina 3 fere mm diam. orbicularia.

Obs. C. Liebmanni a C. Watsoniana floribus interpetiolaribus, omnino apelalis, 
calcare manifesto orbiculari basi subcoarctato, ovulis circ. 44—43, disco deflexo nimium 
distincta. C. Watsoniana magis affinis C. subuligerae Koehne, quae praecipue inflores- 
centiis distinctissimis nec foliosis, pedicellis interpetiolaribus, calcare orbiculari basi 
subcoarctato disco deflexo, ovulis 8—42 differt. Nova nostra species C. subuligeram 
cum C. heteropetala Koehne quasi conjungere videtur.

Forma Reipublieae Koehne. Altior (ad 4 m), folia paullo latiora,
