more genera. When the first edition of this Key was published in 188G, Dr. Asa Gray 

 reduced the genera to three. Since then Prof. Greene has grouped our species under 

 six genera in his Manual of Bay Region Botany. 



GILIA. 



In Bay-Reg. Bit., sections Dactylophyllum, Linanthus and Leptosiphon of this book 

 form the genus Linanthus, in which Ii. fllipes is G. pusilla, var. Californica; L. 

 grandiflorus is G. densiflora; L. bicolor is G. tenella, and three, perhaps good 

 species, forms that have usually been put with G. androsacea, viz: L. parviflorus, 

 L. acicularis, and L. rosaceus; the first a common slender form with pale yellow or 

 white corolla, tinged outside with red or brown; the second with golden yellow flowers, 

 and the third, the rather stout short' form with rose-red flowers, so common on the San 

 Francisco peninsula. 



The following new species, not of the Bay Region, should appear under Gilia, as 

 follows: 



G. serrulata, Greene. Freely and almost diffusely branched, 6 or 8 inches high: 

 leaf-segments and floral bracts all linear- acerose, the margins spinulose-serrate: calyx 

 segments more than twice the length of the tube: corolla with slender, dark-purple, not 

 far exserted tube, and narrowly funnelform throat, the limb of oblong-spatulate white 

 segments, 9 lines broad. 



G. montana, Greene. Habit of G. ciliata, but larger, less hispid: corolla much 

 larger, nearly 2 inches long, the tube widening to a broadly funnelform purple throat: 

 segments of the limb cuueate-obovate, truncate whitish. 



G. nudata, Greene. Slender, 3-10 inches high, branches few: leaves 8 lines long, 

 distant: flowers in dense clusters: corolla tube long, exserted, short yellow throat, and 

 white or purplish limb, 6 lines broad. Lake Co. 



In Bay-Reg. Bot., the species of Navarretia are put in the genus Navarritia, to 

 which are added two new species N. parvula, Greene, and N. mellita, Greene 

 These would here be described under Gilia, viz: 



G. parvula, Greene. Branching, 2-4 inches high, very viscid and aromatic: lowest 

 leaves linear, entire: the upper broader, with teeth or segments: corolla about 4 lines 

 long, broadly tubular-funnelform, light blue: stamens very unequal, the 2 posterior 

 included, the 3 anterior long exserted and declined. 



G. mellita, Greene. Slender, 2-5 inches high, very viscid and honey-scented (hence 

 the name): lowest leaves pinnately divided into spine-like segmets, those of the upper 

 broader but spine-tipped: corolla minute, not exceeding the calyx, bluish: stamens 

 included. Belmont, San Mateo Co. Summer blooming. 



To the preceding may be added the following, published under the name Navarretia, 

 not in Bay Reg. Bot. :
