528 PLANTS FROM LOWER CALIFORNIA. 



733. Calandrinia caulescens II. 1$. K., var. Menziesii Gray. 



Very common. 



712. C. maritima Nutt. 



Steins 2 to 10 inches high, erect and simple, rarely with spreading 

 branches at base ; flowers in an umbel like cluster ; pedicels 3 to 8 lines 

 long; petals 5, small, reddish ; stamens 3 or 4; stigma capitate, barely 

 three-lobed. This is a very rare and little-known species, only having 

 been previously collected by Nuttall, Thurber, and Parry. This yean 

 also by Lieutenant Pond. 



709. Claytonia parviflora Dougl. 



Common. 



616. Malvastrum Thurberi Gray. 

 681. M. exilis Gray. 



Leaves deeply cleft and more sharply toothed than the species. 

 693, 624. Sphaeralcea ambigua Gray. 

 Not before reported from Lower California, although Orcutt probably 

 got it from Japa. 



676. Erodium cicutarium L. Her. 

 618. E. moschatum L. Her. 



715. E. Texanum Gray. 

 666a. Lupinus. 



Stems 5 to 10 inches high, branching at base, pubescence of long an 

 scant hairs; leaflets (3 to 6 lines long) oblanceolate, on long petioles 

 flowers scattered and small (3 to 4 lines long), violet with yellow keel 

 pods one-half inch long, five to six seeded ; seeds brownish, mottled wit 

 black, only one line in diameter; bract deciduous. As we have the 

 genus represented in the National Herbarium our plant seems nearest 

 to L. ArizonicuSj Wat. Its small and scattered flowers also seem to 

 place it in this section. A comparison with the Cambridge specimens 

 indicated a close relationship with L. nanus. Orcutt and others have 

 distributed as L. micranthus, Dougl., a somewhat similar form. With 

 so many uncertain forms before us we leave this until a revisiou of the 

 genus is made. 



666. Lupinus micranthus Dougl. 



716. L. afliiiis Agard. 

 697. Trifolium tridentatum Lindl.

The typical form ; very common. 



690. H. (Syrmatium) Watsoni u. sp. 



Stems shrubby at base, 1 and 2 feet high, branches weak ascending 

 growing parts silky, older parts puberulent; leaflets mostly three, 2 to
