Stylophyllum Parishii Britt. Bull. N.Y. Bot. Gard. 3: 37. 1903. Closely related to 5". edule, from which 

 it is distinguished chiefly by the calyx-lobes which are a little larger, mostly oblong-oval and rounded at the 

 apex. Known only from the original collections and possibly not specifically distinct. Palo Canyon, San Diego 

 County, California.

Caudex stout, bearing several rosettes, very glaucous throughout. Basal leaves nearly terete, 

 6-12 cm. long, acute; flowering stems rather slender and weak, naked below, bearing a few 

 linear leaves above ; inflorescence a rather dense cyme, the ultimate branches short, 4-8-flowered,

Echeveria Orcuttii Berger in Engler & Prantl, Nat. Pflanzenf. ed. 2. 18": 481. 1930. 



Caudex branching and bearing several rosettes. Basal leaves narrowly linear, terete, 3-8 cm. 

 long, very glaucous ; flowering stems rather slender, 15-20 cm. high, with scattering short linear 

 leaves ; inflorescence of one or two elongated loosely flowered secund racemes ; pedicels 1-3 mm. 

 long ; calyx-lobes obtuse ; corolla rose-colored, 7 mm. long ; anthers red.

 the international boundary, and the Coronados Islands south to Todos Santos, Lower California. May— July. 

 This species is closely related to Stylophyllum attenuatum (S. Wats.) Britt. & Rose of Lower California, which 

 differs chiefly in the acute calyx-lobes and the yellowish corolla, and less glaucous herbage. 



6. HASSEANTHUS Rose, Bull. N.Y. Bot. Gard. 3:36. 1903. 



Stems arising from globose or oblong corms. Basal leaves narrowly linear, terete or 

 oblanceolate to obovoid and slightly flattened ; stem leaves ovate to ovate-lanceolate, some- 

 what clasping, fleshy and rather turgid. Inflorescence cymose. Calyx 5-lobed. Corolla 

 yellow or white tinged with rose, united at base into a short tube, the segments narrow, 

 spreading. Stamens 10, inserted on the corolla-tube. Carpels 5, free or indistinctly united 

 at base, widely spreading. [Name in honor of Dr. H. E. Hasse.] 



A genus of three or four species, restricted to southern California and adjacent Lower California. Type 

 species, Hasseanthus variegatus (S. Wats.) Rose. 



Leaves terete at least toward the apex, the basal linear or narrowly linear-oblanceolate, the cauline sharply acute.
