BOTANY OF SANTA CRUZ ISLAND. 395 



of the lateral wanting, membranaceous, cuneate-oblong, an 

 inch long, the apex acute: flower and fruit unknown. 



Here and there a seedling of this obscure but unquestion- 

 ably new species was found in gravelly dry beds of streams 

 in several parts of the island. I judge the perfect plant to 

 be a perennial or a shrub of the mountain sides or summits, 

 but I could never And it. An annual would have been in 

 fruit at the late summer time; but these gave no sign of 

 flower, even. The habit is rather that of Syrmatium, but 

 the leaves are too ample for that genus. I have named and 

 thus defined what I have of this variety, both hoping that 

 future search may be rewarded with perfect specimens, yet 

 fearing lest it be one of the insular species now on the verge 

 of extinction, like Syrmatium niveuni.
