CERTAIN WBSTBRN ROSES. 257 



infrastipular in pairs : leaves long but open, the rachis almost 

 filiform and the small leaflets somewhat remote, always 7, 

 broadly somewhat obovate, all except the terminal one — and 

 this also sometimes — obtuse, doubly serrate, of thin texture, 

 glabrous on both faces, rachis with very few proper prickles 

 and more numerous slender-stiped glands ; stipules of the 

 earliest leaves with broad obtusish lobes, those of the later 

 showing lobes acute to subfalcate-acuminate, the margin sub- 

 serrately glandular : peduncles naked at summit, otherwise 

 sparsely and shortly glandular-bristly. 



Pescadero, San Mateo Co., Calif., May, 1903, A. D. E. 

 Elmer. Extremely hispid as to stems, but foliage small and 

 delicate. 



Rosa calvaria. Shrub rather tall, slender and loosely 

 leafy, the branches of the season only purplish under a coat of 

 bloom, totally naked as to the usual armature of slender 

 spines, these replaced by a pair of long stoutish basally flattened 

 straight spreading infrastipular spines to every leaf : leaves 

 uncommonly long-petioled and lax, of about 7 leaflets, the 

 terminal one well separated from the others by a petiolule of 

 % inch, all rather large, round -obovate, obtuse or even sub- 

 truncate, the primary serratures broad, the secondary ones 

 very numerous, both faces of a pallid green as if glaucous, but 

 both densely soft-pubescent ; the rachis sparsely hispid and 

 densely puberulent ; stipules small and narrow for the group, 

 their lobes not large, triangular -lanceolate : flowers in threes, 

 their peduncles naked, glaucous and even wholly glabrous ; 

 fruit not seen.

Rosa abibtorum. Shrub apparently low and straggling,
