little over an inch in length, and when apparently mature not at all 

 obcompressed but somewhat flattened laterally, with the acute ventral 

 suture salient, completely bilocellate. 



Astragalus Artiiu-Schottii, Gray, Rev. Astr., char, fruct. 

 emend. : spitharaa;us ad tripedalem ; legumine raaturo ovato acuminate 

 (lin. 7-8 longo) canescente chartaceo ad suturam ventralem pro- 

 fundius sulcato ob septum dorsalem corapletum bilocellato. — In sand 

 on the Mohave River, at Camp Cady and elsewhere, Dr. J. G. Cooper. 



Astragalus Bolanderi : subpedalis, cinereo-puberulus ; stipulis 

 brevibus scariosis adversus petiolum connatis ; foliolis G-9-jugis 

 sublinearibus oblongisque ; pedunculis folio brevioribus capitato-pluri- 

 floris ; pedicellis brevi&simis, fructiferis reflexis ; legumine in stipitera 

 e calyce exsertum hamato-incurvo ovato acutato obcompresso turgido 

 coriaceo glabro (lin. 8-9 longo 3 — 4 lato) polyspermo ob septum com- 

 pletum bilocellato. — Dry ground, at Ostrander's Ranch, Yosemite 

 Valley, Bolander. Flowers not seen. The teeth of the calyx are 

 almost setaceous, and more than half the length of the cylindraceous 

 tube. Stipe 4 lines long. The species is to be ranked, perhaps, with 

 the Oroboidei, although the stipules are connate and the legume com- 

 pletely two-celled. 



Lathyrus Torreti : pusillus (spithamajus ad pedalem), villoso- 

 pubescens ; radice perenni ; stipulis semisagittatis angustis ; foliolis 

 4 - 6-jugis ovalibus mucronatis (lin. 4 - 8-longis) ; cirrho simplici 

 saspius brevissimo ; pedunculo brevi vel brevissimo srepius unifloro ; 

 calycis lobis setaceo-subulatis tubo duplo longioribus ; corolla pur- 

 purascente ; legumine pauci-ovulato monospermo in pedicellum deflexo. 

 L. ? villosus, Torr. in Stevens (Cooper & Suckley) Pacif. R. R. Rep. ; 

 a preoccupied name. — Mendocino or south part of Humboldt Co., 

 Bolander. A neat and peculiar little species, very different from any 

 other, at least in North America, in slenderness, in the small size of 

 the leaflets, and the single-flowered peduncles. The latter are some- 

 times scarcely longer than the stipules, and seldom half the length of 

 the leaf. Bolander's specimens are past the flowering state ; the young 

 legume minutely pubescent, semi-oblong, flat, apparently maturing only 

 a single seed. 



Prunus (Amtgdalus) Andersonii : glaberrima ; ramis spi- 

 nescentibus ; foliis fasciculatis parvis (lin. 4-9 longis) spathulatis ob- 

 longisve obtusis tenuiter subnervoso-venosis subserrulatis eglandulosis ; 

 floribus longiuscule pedicellatis ; calycis (ebracteolati) lobis iuteger-
