PLANTS FROM BAJA CALIFORNIA. 145 



HoSACKiA PROSTRATA Niitt. — SocoiTO, San Quintin. 



HosACKFA MICRANTHA Nutt. — San Pablo, San Sebastian, 

 El Ranclio Viejo. 



Dalea canescens^ Bentli. — Prostrate: flowers deep pur- 

 ple: stamens 10: style very long, stigma not capitate. 



Dalea dlv^aricata Benth. In this species, as well as the 

 very closely related D. Farri/i, the second ovule is often 

 so early and completely aborted that it escapes all except 

 the most careful search. If only the herbaceous stems had 

 been collected, it might easily have been mistaken for an 

 annual, but it is a perennial with a woody base. The vex- 

 ill um is reniform and glandular, the anthers bear a large 

 gland at the apex. — Magdalena Island. 



Dalea Parryi T. & G.— Santa Margarita Island, Patro- 

 cinia, Agua Dulce. 



Dalea, sp. Near D. Parryi but with longer leaflets and 

 somewhat longer calyx teeth. Apparently annual. — San 

 Enrique, San Jalian. 



Dalea chrysorrhiza Gray. The specimens are old, but 

 are evidently of this species with fewer leaflets and larger 

 heads. The flowers are very shortly pedicellate; the very 



*A revision of Dalea by some one having' access to the original specimens is 

 becoming a necessity. Many of the early descriptions are so brief that it is 

 difficult to distinguish allied species by them, and the anomaly of identical 

 names by different authors for different species adds to the confusion. As for 

 instance: Martens & Galeotti in Bull. Acad. Brux.X, No. 7, 40, and soon after 

 Bentham in Bot. Sulph. described four different species under the names ca- 

 nescens and ramosissima. In the Index of N. A. Botany, D. canescens and 

 ramosissima are credited to Bentham and a reference is given to Walp, Rep. 

 ii, 513. This is probably a -typographical error in Dr. Watson's invaluable 

 work, and is perhaps meant for p. 855 instead, for on that page are found the 

 names, but they are for the species of Martens & Galeotti. Mr. Hemsley, 

 in Biolog. Cent. -Am., makes no reference to the flora of Baja California 

 escaping thereby the nei-essity of noting D. canescens, and reduces D. 

 ramosissima, Mart. <k Gal., to a synonym of D. diffusa.
