632. Poa stenantha Trin. Probably also P. leptocoma Trin. 

 and certainly Festuca nervosa Hook. Fl. Bor.-Am. t. 232. 



633. Poa andina Nutt. herb. ; a condensed form with larger 

 spikelets. 



634. Poa tenutfolia Nutt. in herb. ; Watson, Bot. King, p. 387. 

 Poa melicoides Nutt. in herb. Durand and herb. Lowell. The proper 

 genus perhaps is Atropis, and indeed the present species appears to 

 pass into Atropis Californica (or Schlerochloa Californica) Munro. 



635. Melica bulbosa Geyer in Hook. Kew Jour. Bot. (PI. 

 Geyer.) 8, p. 10. 31. poceoides Torr. Bot. Whippl., Bolander, &c, non 

 Nutt.* Geyer's name is preferred in the absence of any reason for 

 changing it to 31. Geyeri, as Munro proposes ; especially as the plant 

 described under this name by Bolander is different.! 



636. Lophochl^ena refracta, n. sp. Ab affini L. Californica 

 insigniter differt foliis latioribus (lin. 4 latis), racemo virgato, spiculis 

 mox refractis angustioribus fere linearibus, floribus subdissitis, paleis 

 tenuioribus fere laivibus, arista palea ipsa breviore. — An interesting 

 accession to a remarkable genus, which, it seems to me, should stand 

 next to 3felica. I possess no specimen of " Melica aristata Thurber " 

 in Dr. Bolander's revision of the genus : but 3felica Harfordii of 

 Bolander is evidently an intermediate link. 



637. Festuca Mturus L., the F. bromoides L. also. 



638. Festuca microstachts Nutt. PI. Gamb. p. 187. 639. Var. 



* Melica poceoides Nutt. PI. Gamb. p. 188, is described as from Dr. Gambell's 

 collection, and is said to come from the " Island of Santa Catalina," — which 

 Gambell visited, but NuttalL did not.- In the distributed set of Gambell's plants 

 acquired by Mr. Lowell, and in that for Mr. Durand (now in my possession), there 

 is no " Melica poceoides." There is, however, a " Poa melicoides " from " Catalina," 

 which is the same as no. 634 of the present collection, namely, a plant which 

 Nuttall named " Poa tenuifolia." 



By the kind aid of Dr. Carruthers, keeper of the herbaria of the British 

 Museum, I am enabled to say that the " Melica poceoides Nutt. MSS." of his own 

 herbarium, and apparently of his own collecting, is ticketed " San Diego." But 

 it is pretty clearly the plant described in PI. Gamb. It differs from the M. pani- 

 coides of the same paper in having (as described) two perfect flowers in most of 

 the spikelets, while that has commonly only one ; but both belong to Melica im- 

 perfecta Trin. i 



t Melica Geyeri Bolander in Proc. Calif. Acad. 4, p. 102, as represented by no. 

 40 of his small collection, is very unlike M. bulbosa of Geyer's collection. To 

 obviate further confusion, it would be well, and perhaps not too late, for Dr. 

 Bolander to restore to it specifically his appropriate name of M. bromoides.
