CALIFORNIA. 17 
This species is near D. holosteoides, but forms dense tufts covered with 
leaves and flowers; the leaves are thicker and more glaucous, and the flowers 
larger, and on longer stalks. Both species differ considerably in habit from 
the more common D. cordifolia, but they have all the essential characters of 
the genus.

whence it was first described.

Cuar. Gen. Sepala 5, ovata, margine membranacea, estivatione imbricata. Petala 5, 
perigyna, calyce minora, orbiculata, integra, brevissime unguiculata. Stamina 10, in annulum 
perigynum basi connata, filamentis e basi latiore filiformibus, antheris bilocularibus, Ovarium 
sessile, subglobosum, uniloculare, columna centrali percursum. Ovula 5, anatropa, e basi columne 
centralis erecta. Styli 5, breves, recurvi, intus fere a basi stigmatosi. Capsula pentagona, 
unilocularis, ad angulos in valvulas 5 dehiscens. Semina 5 vel abortu pauciora, singula arilla alba 
e funiculo orta intus aperta involuta, erecta, testa crassiuscula fusca, embryone annulari ? 
Species unica, S. halimifolia. Frutex ramosissimus, glaberrimus, glaucus, ramis adscendentibus, cortice 
pallido, Stipulee nulle. Folia alterna, petiolata, 1-14-pollicaria, ovata vel oblonga, obtusissima, integerrima, 
basi angustata vel rotundata, carnosula, uninervia. Racemi terminales, simplices, floribundi, subtripollicares. 
Pedicelli 3 lin. longi, singuli ex axilla bracteee minute scariosee orti et ima basi bibracteolati, bracteolis bracteis 
consimilibus. Flores iis Limet capensis subsimiles, sed paullo majores. 
The nearest affinity of this very distinct genus is with Limeum. The calyx 
and petals are the same, but the number of stamens appears to be constantly 
complete, the carpels are five instead of two, and are completely united into an 
unilocular ovary and fruit without any dissepiments, and the seeds are enclosed in 
a very remarkable thick white arillus. I regret much that there are none of 
them quite ripe enough in the specimens gathered, to ascertain the form of the 
embryo.
