FOUQUIERIACEtE. 



228. FouQUiERA SPLENDENS, Engehi. in Wislis. Mem. N. Mex. p. 98. F. spi- 

 nosa, Torr. in Emory, Rep. p. 147. t. 8. excl. syn. " A shrub with very long 

 branches from near the root, growing on hills, beyond the San Pedro River, with- 

 out flower or fruit." — Dr. Engelmann and Dr. Torrey have well shown, by their 

 observations on the ovary and fruit of this species, that Bronnia is not distinct from 

 Fouquiera. The structure of the flowers of F. splendens is the same as in F. for- 



. mosa, but they are more slender and on slender pedicels, while those of the latter 

 are closely sessile. The (corymbose) flowers and fruit of F. (Bronnia) spinosa are 

 in Coulter's Mexican collection (No. 919, from Sonora Alta). The former are as 

 described by Bentham (in Bot. Voy. Sulph.), except that the expanded corollas are 

 straight and nearly an inch in length : the capsules, seeds, &c. are as described and 

 figured by Kunth. The broad wing of the seed is composed of long, spirally- 

 marked cells, just as remarked by Torrey in Fouquiera splendens ; and the fila- 

 ments are glabrous throughout. — There are fruiting specimens in the collection 

 of 1851. 



CRASSULACE^. 



228^. EcHEVERiA STRicTiFLORA (sp. nov.) : foHis radicalibus spathulato-lanceola- 

 tis, caulinis lanceolatis parvis, floralibus similibus flore dimidio brevioribus; flori- 

 bus breviter pedicellatis arete secundis appresso-erectis in spicam simplicem strictam 

 confertis ; petalis longe attenuato-acuminatis sepala oblonga duplo superantibus. — 

 Mountains west of the pass of the Limpia ; Aug. " Flowers scarlet," in a very 

 strict and close secund raceme or spike, of six or eight inches in length: the 

 flowers two thirds of an inch long ; pedicels two or three lines long. — There is 

 an allied species in the collection of Dr. Wislizenus, which I cannot identify with 

 any described.* 



229. Sedum Wrightii (sp. nov.) : glabra, caulibus decumbentibus ; foliis spar- 

 sis crasso-carnosis obovatis, ramorum floriferorum oblongis basi solutis; floribus 

 brevissime pedicellatis in cymam densam 2-3-fidam digestis secundis; petalis 5 

 spathulatis obtusis mucrone apiculatis (albis roseo tinctis) sepalis oblongis obtusis 

 duplo longioribus. — Hills near the San Pedro River, in crevices of rocks, and sum- 

 mit of mountains near El Paso, New Mexico; Aug. -Oct. — Perennial, with fibrous 

 roots ; the stems diffusely spreading, or at first erect, a span or more in length. 

 Leaves 3 or 4 lines long. Cyme very compact. Flowers larger than in S. Mora- 

 nense ; the petals 3 or 4 lines long, and broadly spathulate or obovate. Carpels 

 abruptly apiculate with a slender style. 



* EcHEVERiA PANiciTLATA (sp. nov.) : foliis radicalibus obovato-Iingulatis, caulinis sparsis parvulis lan- 

 ceolatis canaliculatis, omnibus mucronato-acutis ; floribus laxe paniculatis undequaque versis ; petalis apice 

 breviter recurvis sepala duplo superantibus. — Cosiquiriachi, Northern Mexico, Wislizenus. — Flowering 

 stems a foot long above the rosulate and apparently radical tuft of leaves ; the latter 2 or 3 inches long, 

 the scattered or subopposite stem-leaves from half an inch to an inch in length. Flowers half an inch 

 long, disposed in a loose, elongated panicle : the proper terminal flowers are on very short peduncles, the 

 lateral ones mostly with rather long, bracteate peduncles. Bracts small, linear.
