VITACE.E. 29 



Greene makes a new native species of Erodium (E. Californicum) distinguished 

 from E. macrophyllum by deep rose-red flowers, instead of dull-white. 



Limnanthes is Fleer kea in Bay-Reg. Bot., and Oxalis is Oxys. 



Oxalis Oregana has usually solitary flowers on 2-bracteate scapes. O. trillifolia 

 has flowers in bracteate umbels. 



RUTACEJE. 



Pellucid or glandular-dotted aromatic leaves, along with definite hypogynous stamens 

 characterize this order, although some of the orange-tribe have many stamens. Shrubs 

 or trees. Key to genera and species, p. 101 . 



CELASTRACE^E. 



Shrubs with simple undivided leaves and dull-colored or white flowers. Sepals, 

 petals and stamens 4 or 5: stamens on a disk. Key to genera and species, p. 102. 



RHAMNACE^E. 



Shrubs or small trees, with simple undivided leaves, small and often caducous stipules, 

 and small regular flowers, the stamens borne on the calyx aud alternate with its lobes: 

 ovary 2 to 4-celled. Flowers often apetalous: a conspicuous disk adnate to the short 

 tube of the calyx: petals often clawed: style or stigma 2-4 lobed: fruit berry-like or 

 dry, containing 2 to 4 seed-like nutlets. Key to genera and species, p. 102. 



According to Greene, Bhamnus ilicifolia, Kellogg, may be distinguished from B. 

 crocea by its greater size, the latter only 2 or 3 feet high, and the parts of the flower 

 in 5's, not 4's. 



Bhamnus Purshiana is Cascara sagrada, by far the most notable medicinal plant 

 of this coast. 



B. Californica is absurdly called California Coffee. 



VITACE^E. 



This small order is represented on this coast by one species, Vitis Californica, 

 known as the California grape. In the Atlantic states there are half a dozen species. 

 In Europe probably no native species. Virginia Creeper, Ampelopsis quinquefolia, com- 

 monly cultivated, belongs to this order. Botanists think all the wine and raisin grapes 

 cultivated in Europe are varieties of one or two species. Isabella, Catawba and other
