BOT.-VOL. I.] EASTWOOD-STUDIES FROM THE HERBARIUM. Ill 



not be unlikely to find the species in Alameda County, grow- 

 ing in the vicinity of Vaccmmm ovatum and Castanopis 

 ch rysopliylla . 



In a genus like Amsinckia where there are so many 

 closely related forms, nothing definite can be discovered 

 concerning the limitation of species until these various 

 forms are represented growing in a botanic garden under 

 similar conditions; nor is it possible to be sure of what 

 characters are constant. 



In view of all these doubts, it seems best to describe these 

 two closely related island plants as distinct species. If the 

 last proves upon further investigation to be similar to the 

 common maritime species found all along the coast, the 

 name will appropriately include them ; while the other, per- 

 haps Gray's var. bracteosa of his A. lycofsoides, is named 

 in honor of the Island's saint. 



SOLANACE^. 



60. Lycium verrucosum, sp. nov. 

 Plate VIII, Figs. ia-2,d. 



Glandular-puberulent, shrubby, 6-8 ft. high, divaricately branching, spines- 

 cent, bark light gray ; branchlets verrucosa at leaf axils from downy tufts at 

 base of petioles : leaves spatulate, 5-15 cm. long, narrowing to the petiole, 

 thick, obsoletely one-nerved : flowers small, solitary in the axils, on pedun- 

 cles 2-7 mm. long ; calyx campanulate, irregulariy 4-cleft, divisions oblong, 

 obtuse, thickish, reticulate, i mm. wide ; corolla lavender, 8 mm. long, with 

 tube slightly surpassing the calyx, hairy within below the throat, border of 

 four rounded, spreading divisions, each 2 mm. wide ; anthers thick, sessile 

 in the throat of the corolla ; ovary somewhat crested at summit; stigma cap- 

 itate on a level with the anthers ; immature fruit reddish. 



This belongs to the same group as L. Calif ofnictcm and 

 L. barbinoduni from which it can be readily distinguished 

 by the floral organs. 



It grew in several localities on arroya cliffs, with its 

 branches hanging over the arroyas in many an inaccessible 

 erosion.
