8 Chase — Notes on Genera of Panic ex. II. 



Sacciolepis strumosa (Presl). 



Panicum strumosum-Fresl 1830, Eel. Haenk. 1 : 303. " Hab ad Monte- 

 Rey Californise." Tlie type in the Presl Herbarium is labeled "Panicum 

 strumosum nov. sp. J. S. Presl " ; a second slip reads " Regno montanse, 

 Haenke." The published Ideality is clearly a mistake; no species of this 

 group have been found in California. This species is represented in the 

 National Herbarium by Burchell 4420, Brasil. 



Sacciolepis indica ( L. ) 



Aira spicata L. 175.'!. Sp. PI. 63. " Habitat in India." In the Errata 

 at the end of Vol. 2 " spicatum" is changed to " indicum," presumably 

 because of another Aira apicata on page 64. " The specimen in the Lin- 

 nean herbarium is a delicate creeping or spreading plant with many spikes 

 about 1 cm. long with only a few spikelets"" — [Hitchcock in notebook]. 

 It is labeled in Linnaeus' hand " Panicum indicum." Aira has been 

 scratched, and indica changed to indicum. 



Aim indica L. 175:!, Sp. PI. in Errata; 17(12, Sp.' PI. ed. 2, (14. 



Panicum indicum L. 1771, Mant. 2: 184. Based on "Aira indica -Sp. 

 plant 94" (the reference is to the second edition). 



Hymenachne indica (L.) Buese 1854, in Miq. PI. Jungh. .">77. Based on 



Panicum indicum \.. 



Of the several species in the National Herbarium from India received 

 as Panicum indicum 1... that represented by Duthie 10,003 from the herb- 

 arium of Prof. Hackel seems to be the true /'. indienm. 



Sacciolepis curvata (L.). 



Panicum curvatum L. L767,Syst. Nat. ed. 12: 732. ''Habitat in Su- 

 ratte." 



IPanicum coryophorum Kunth 1831, Rev. Gram. 2:387. 1. 107. " Cres- 

 cit in Madagasearia." Communicated by Aubert du Petit-Thouars. 

 Kunth remarks that while the description of P. curvatum L. might in- 

 clude his species, it is nevertheless too brief to convince him of the iden- 

 tity of the two, especially since one is from India and the other from 

 Madagascar. The Madagascar specimen in the National Herbarium 

 agrees perfectly with Kunth's figure, but the identity of /'. curvatum L. 

 and /'. coryophorum Kunth can only he determined by a study of the types. 

 The two are considered synonymous by Hooker, Stapf and others. This 

 is the only known species with an open panicle. The spikelets closely 

 resemble those of the type species, S. gibba. 



The following species which belong in this genus are not here trans- 

 ferred for lack of complete data: 



Panicum rigidifolium Trim 1829, Sp. Gram Ic. 2. t. 214. " Figura ad 

 specimen Brasiliense." The type in Trinius herbarium, St. Petersburg, 

 is labeled " Panicum rigidifolium m. 4 Brasil. Langsdorff." 



This is an outstanding species with a fruit larger in proportion to the 

 size of the spikelet than in any other species. It is not here transferred 

 because of uncertainty as to the oldest tenable name. Kunth (1833, 

 Enum. PI. 1: 88) changes the name of P. rigidifolium Trin. to Panicum
