651. Eragrostis ciliaris L. var. patens Chap. — 

 San Jose del Cabo. 



652. Eragrostis Purshii Schrad. — Collected by Dr. 

 Palmer at La Paz. Cont. U. S. Herb., iii, 78. 



653. PoLVPODiUM Pi.EBiUM Schl.* The form with 

 obtuse segments like Parry & Palmer's No. 973 from 

 San Luis Potosi. Except for the scales on the frond this 

 has very much the look of P. vulgare. — Sierra de la 

 Laguna. 



654. PoLYPODiuM plesiosorum Kunze ? A single 

 frond, not very typical of this species, but better placed 

 here than elsewhere. — High mountains of the interior. 



655. Gymnogramme trifoliata Desv. — Growing in 

 the hedges at Todos Santos. 



656. NoTHOL^NA NivEA Dcsv. A large and stout 

 form like some from Chiapas collected bv Ghiesbrecht. 

 — Sierra de la Laguna. 



657. NoTHOL.^NA CANDIDA Hookcr. — SieiTa de la 

 Laguna. 



658. NoTHOL.^NA FERRUGiNEA Hooker. — Sierra de 

 la Laguna. 



659. NoTHOL.^NA Lemmoni D. C. Eaton. — Todos 

 Santos, La Paz. 



660. Cheilanthes Pringlei Davenp. — The speci- 

 mens differ from the type in having longer fronds with 

 more distant pinnae, and the pinnules oblong rather than 

 ovate. The fronds, too, are rather less scaly along the 

 rachises. Possibly they should be described as a dis- 

 tinct species, but some of Palmer's specimens from Chi- 

 huahua (No. 116 of 1885) seem to connect them with 

 the original form from Arizona. — Canons along the base
