ESCHSCHOLTZIA, Cham. From the mass of diverse forms 

 which, in the hick of a better understanding, we have been in the 

 habit of accumulating under the name of E. Californica, Mr. Watson 

 first separated a very small-flowered one as E. minntijiora ; and re- 

 cently Prof. Greene, in a monographic revision of the genus, has de- 

 scribed several species. Unfortunately he had not the types of the 

 older annual species. The recognition of E. CaUfornica as a peren- 

 nial, which, though long known, had been generally overlooked (be- 

 cause it promptly blossoms the first year and is cultivated as an annual), 

 has been helpful. It was not quite clear what E. ccBspitosa, E. tenui- 

 folia, and E. hypecoides were founded on ; and a further uncertainty 

 was introduced by Mr. Bentham's reference, ir^ Plautae Hartwegi- 

 anai, of an obvious E. Galifornica to E. temiifolia, although with 

 misgiving. An inspection of the originals now makes it clear that 

 these three annual species are all one. E. ccespitosa and E. temiifolia, 

 which are quite alike, represent the form with leaves mainly subradical, 

 and E. hypecoides, a leafy-stemmed and shorter-peduncled form. It 

 should be mentioned, however, that, in tlie Kew herbarium, the only 

 original of E. ccespitosa is that of the Hookerian herbarium. If there 

 was one in that of Bentham (as is probable), it is not in place. Of 

 these three specific names that of E. ccespitosa should be preferred for 

 the species, that of E. hjpecoides relating to a less usual form, proba- 

 bly growing in shade. Then the name of E. temiifolia, Hook, (not of 

 Benth.), may be retained for the very distinct species figured in Bot. 

 Mag. t. 4812, and taken up under this name by Greene, who detected 

 the unique character of its seeds. 



I cannot yet well define the species, but the subjoined arrangement 

 may be ofiered.f

1. Dilated torus funnelform, bearing an expanded rim outside of the insertion 

 of the calyptrate calyx (but variable in width) : mature seeds with a coarse and 

 salient superficial reticulation of the episperm : anthesis of 3 or 4 days. 



* Perennial, large-flowered. 



E. Caltfornica, Cham., of which E. DouglasU, Torr. & Gray, and E. temiifolia ? 

 Benth. PI. Hartweg. 296, are forms with narrower border to the torus. 



* * Winter annual, low, small-flowered : petals 5 to 8 lines long. 



E. PEXiNSCLARis, Greene, Bull. Calif Acad. i. 68. Southern and Lower Cali- 

 fornia, where it is the common species. 



2. Dilated torus destitute of expanded rim or border, although the margin 

 sometimes becomes sphacelate in age, a hyaline internal edge (within the inser-
