Umbelliferm.] CALIFORNIA. 141 



recently in the valuable Reliquim Hamheana of Presl. That author thus defines the generic character : 

 Cal. superus deciduus, tubo infundibuliformi cum ovario articulate, colorato, basi supra ovarium globoso-ven- 

 tricoso, limbo quadripartite. Petala quatuor, summo tubo inserta. Antherm lineares, dorso affixn>. Ovarium 

 lineare, tetragonum. Stylus filiformis. Stigma capitatum, 4-lobum. Capsula linearis, tetragona, quadri- 

 valvis, unilocularis, polysperma. Semina oblonga, papposa. — Suffrutices decumbentes, ramosissimi, tomento 

 tenui canescentes. Rami oppositi. Folia opposita, angusta. Racemi terminates, simplices. Flores sessiles,

Ord. XVIII. CUCURBITACEjE. Juss. 



There are two Cucurbitaceous plants in the Collection, but without flower, and probably cultivated, as is 

 assuredly the case with a Mesembryanthemum in the Herbarium.

There is still a third species of Ribes (Sect. Grossularia.) in the Herbarium, with a solitary stipulary 

 spine and no aculei, and with leaves resembling those of R. Cynosbati, only thrice as large : but being 

 destitute of flowers and fruit, it cannot be determined.
