 that I was not aware of their true arrangement until the engraving of the plant 

 was finished, arc not found in any other Rosacose, so far as I know. 



EMPLECTOCLADUS, Nov. Gen. 



Calyx obconico-campanulatus ; tubo ad faucem nudo baud contracto ; limbo 

 sequaliter quinquepartito, persistente. Petala 5, erecto-patentia. Stamina 10-13, 

 biserialia. Pistilla 1-2 (plerumque solitaria) unilocularia : ovula 2, collateralia, 

 pendula. Stylus brevissimus, crassus, subobliquus : stigma capitatum. Fructus 

 ... — Frutex Californicus, ramosissimus ; ramis rigidis, patentibus, subspines- 

 centibus ; foliis minutis, spathulatis, e gemmis subglobosis quasi fasciculatis ; 

 stipulis minutis deciduis ; floribus subsolitariis, sessilibus, terminalibus, parvulis. 



EMPLECTOCLADUS FASCICULATUS. Tab. V. 



Hab. — Sierra Nevada of California ; probably in the southern part of the range. 



A shrub, with numerous widely spreading branches, which have a knobbed 

 appearance from the short rounded buds or spurs ; the bark smooth and of an 

 olive color. The leaves are crowded on the spurs, three to four lines long, cuneate- 

 spatulate, obtuse, sessile, of a thick and somewhat coriaceous texture, flat, marked 

 with a single nerve underneath, sparsely hirsute with mostly deciduous hairs, and 

 furnished with minute scarious stipules. The flowers are mostly solitary, surrounded 

 by the closely set leaves, and are scarcely more than a fourth of an inch in diameter. 

 Externally the calyx is glabrous, but woolly inside ; the teeth short and obtuse. 

 The petals are apparently white, ovate-oblong, obtuse, about one line and a half 

 long, and are destitute of a claw. There are usually about eleven stamens, the 

 slender filaments of which are inserted in two rows near the summit of the cal3^x- 

 tube, the superior or exterior ones being about as long as the petals : anthers 

 subglobose-didymous, introrse ; th% cells distinct, opening longitudinally Pollen 

 obtusely triangular (as is also the case in Adenostoma and many other Rosaceae). 

 Pistils usually solitary, but sometimes in pairs, seated at the bottom of the 

 calyx, and free from it. The ovary is ovoid, abruptly contracted above into a very 

 short and somewhat oblique style, which is terminated by a depressed-capitate 

 stigma. There are two ovules, which are anatropous, and suspended from the 

 summit of the cell opposite the style. Nothing is yet known of the ripe fruit. 



The only specimens of this plant brought by Colonel Fremont had unfortunately 

 lost their labels, so that we have no cei'tain information as to its precise station, 

 and of tlie size which it attains. Neither, for want of the fruit, can we determine 

 its nearest affinities. It is probable, however, that the genus belongs to the Tribe 

 Dryadea). In many respects it resembles Adenostoma of that tribe, but it differs
