52. Panicum, Linn. Stapf in Prain Fl. Trop. Afr. IX, 638. 



Annual or perennial grasses, rarely suffrutescent, of various habit and size, 

 leaves mostly linear to linear-lanceolate, but also ovate or filiform to subulate. 

 Ligules usually reduced to a ciliate rim or a fringe of hairs, rarely a distinct 

 membrane or 0. Panicles usually much divided and at least temporarily open, 

 Spikelets usually loosely scattered, glabrous or hairy, lanceolate to oblong, 

 •elliptic or orbicular in outline, symmetrical in profile, rarely somewhat oblique, 

 falling entire or almost so from the often elongated pedicels of a compound or 

 decompound panicle, without -a definite orientation towards the axis. Involucral 

 glumes more or less herbaceous-membranous, lower usually shorter than the 

 upper, often very much so, rarely equalling it, usually with lor more nerves, 

 or if very small, nerveless ; upper as long as the spikelet, rounded on the back, 

 -5-9-nerved Lower floral glume very similar to the upper involucral glume 

 and equally rounded and curved on the back, 5-9-, rarely 3- or 11-nerved, 

 .male or neuter, pale thinly membranous to subhyaline, subequal to the lower 

 floral glume or more or less reduced, rarely suppressed.. Upper floral 

 •glume subcoriaceous to coriaceous with firm margins, obtuse to subacute, 

 emucronate, faintly nerved,, hermaphrodite, pale subequal to the glume and of 

 .■similar substance, tightly embraced by the more or less involute margins of the 

 glume. Lodicules 2, broadly cuneate. Stamens 3. Styles distinct ; stigmas 

 laterally exserted near the tip of the floret. Grain tightly enclosed by the 

 (hardened valve and valvule, dorsally compressed, biconvex to almost plano- 

 convex ; scutellum elliptic to ovate-elliptic, about half as long as the grain ; 

 hilum subbasal, punctiform. 



Species about 400. in the tropical and subtropical regions of both .hemis- 

 pheres, few an the warm-temperate regions. 



Cooke mentions 20 indigenous and 4 cultivated species. 



Of the 24 species we have put Panicum flavidwm, Retz., P. punctatum, 

 Burm., and P fluitans under Paspalidium. 



Panicum stagninum, Retz. and P. colonum, Linn, have been transferred to 

 Echinochloa. 



Panicum Isachne, Roth, P. ramosum, Linn, and P. muiicum, Forsk. belong 

 to Brae hi aria. 



Panicum pro stratum, Lamk , P. setigerum, Retz. and P. javanicum, Poir. 

 fhave been described under Urochloa. 



Panicum interruptum, WMld. and P. myosuroides will be dealt with under 

 Sacciolepis. 



Panicum patens , Linn. w 7 ill be transferred to Cyrtococcum. 



New to the Presidency are P. psilo<podium, Trin, and P. aur-iium, Presl, 



A. Lower involucral glume as long as the lower 



floral glume or nearly so ... ... 1. P. turgidwn. 



33. Lower involucral glume shorter than the 

 •lower floral glume 

 I. Annuals 



1. Leaves less than 12 mm. broad 



a. Panicle about 35 cm. long... ,... '2. P. obscurans. 



b. Panicle not more than 25 cm. long 



aa. Spikelets gaping ... ,.. 3. P. trypheron.
