Description : Cke. I.e. 



Locality: Sind : (Duthie teste Cooke); Sehwan, sand hills (Bhide !).— 

 Gujarat : Rajkot, Kathiawar (Woodrow teste Cooke). 



Distribution : Tropical Africa, Egypt, Cyprus, S. Palestine, Arabia, Socotra, 

 S. Persia, Baluchistan, Sind, Gujarat. 



Uses : An excellent fodder for camels. 



2. Panicum obscurans, Woodr. in Journ. Bom. Nat. Hist. Soc, xiii (1901), 434 ; 

 Cke. ii, 935.- Isachne obscurans, Woodr. in Gard. Chron. 23, ser. 3 (1898/, 161. 



Description : Cke. I.e. 



According to Woodrow the whole inflorescence breaks off and is driven about 

 by the wind. 



Stapf says that the tropical African Panicum hippothrix, K. Schum. is very 

 similar and perhaps identical with P. obscurans, biit he adds that the blades cf 

 the latter are much wider, measuring up to 14 mm. and that the panicle ' is 

 perhaps on the whole mmre open with slightly larger spikelets.' (In Prain Fl. 

 Trop. Afr. ix, 699.) These are scarcely differences to justify specific distinction, 

 but as we have not seen the African plant, we do not venture to decide the 

 point. If the identity between the two species should be established, Woodrow 's 

 specific name, being of a later date by four years, will have to cede to 

 P. hippothrix. 



Locality : Deccan : Mangiri Farm (Herb. Econ. Bot. Poona!) ; Jeur near 

 Sholapur (Woodrow). 



Distribution : Endemic. 



3. Panicum trypheron, Schult. Mantiss. ii (1824), 244 ; Hook. f. in F.B.I, vii, 47 ; 

 Prain Beng. PI. 1176 ; Cke. ii, 936 ; Haines in Bot. Bihar & Orissa 995.— 

 P. miliare, Wall. Cat. No. 8712 (partim) E.—P. mucronatum, Heyne in Wall. Cat. 

 No. 8717 {partim).— P. Neesianum, Wight & Arn. ex Steud. Syn. Gram. 74.— 

 P. Roxburghii, Spreng. Syst. i, 320 ; Kunth Enum. PI. i, 126 ; Steud. I.e. 98.— 

 P. tenellum, Roxb. Fl. Ind. i, 306 ; Duthie Grass. N. W. Ind. 7. 



Stapf in Prain Fl. Trop, Afr. ix, 712 has separated P. porphyrrhizos , Steud. 

 from P. trypheron, Schult, as understood by Hook. f. in F.B.I. I.e., and with it 

 all the material covered by the following synonyms : P. confine, Hochst. ex 

 Steud. Syn. PI. Glum, i, 72.— P. jumentorwn, A. Rich. Tent. Fl. Abyss, ii, 373 

 (non J acq.). — P. trypheron, therefore, does not occur in tropical Africa. 



Description : Cke. I.e. 



Locality: Gujarat: On the Idar Frontier, Prantij Taluka, sandy waste 

 (Sedgwick \).—Konkan: Malabar Hill (Lisboa teste Cooke).— Deccan : Poona
