ISCHÆMUM. ANDROPOGONEÆ (AUCT. EDUARDO HACKEL). 243 
Gluma IV: II» subæquans, linearis, hyalina, uninervis, glabra, infra 
apicem bidentulum v. ex apice acutiusculo aristam emittens gracilem 
imperfectam basi spiris 1—2 laxis munitam ceterum rectiusculam 
brunnescentem 6—9 mm. longam. Palea quam gluma IV* ’/, brevior, 
late ovalis, obtusissima, integra v. denticulata, hyalina, enervis, apice 
fimbriata. Stigmata linearia, dense plumulosa, stylos equantia. 
Himalaya bor. occid. (Hook. f. et Thoms.); Nepal (Royle 237, 229 ; 
Wall. 8845 A. B) ; Sikhim (Hook. f. et Thoms.) Dengalia pr. Tschand- 
ranagar (Koenig), Sahibgange (Kuntze); Ins. Philippine (Cuming 
1002); Formosa (ex Hance); China, prov. Yun-nan pr. Ta-pin-tze 
(Delavay in h. par.). 
Obs. Planta quoad genus satis dubia. Spieularum structura potius 
Spodiopogonis quam Ischæmi, sed inflorescentia ab illa Spodiopo- 
gonum maxime diversa, illam Ischæmi v. Pollinie referens. Quominus 
huic ultimo generi inseratur (quod faciunt Bentham et Hook. in Gen. 
Pl. el. Hance secuti), obstat gluma LI" a latere subcompressa sine 
carinis lateralibus, nervis imparibus validis instructa. Haud dubium 
erit aptissimum, ut genus novum evitetur, Ischæmi generi adjungere, 
a quo minus diserepare mihi videtur quam a Spodiopogonibus, Polli- 
niisque.
