Rocky Mountains to the Pacific, in Northern California and Washington 
Territory, this is only known at one station in the Alleghany Mountains, 
and makes an addition to the list of those few genera (such as Boykinia

ZizyPuus* Lycioipes, Gray, var. CANESCENS, Gray.—A much branched 
shrub, 4-5° high; younger branches covered with a light gray powdery 
substance, which is readily scraped away, leaving the green epidermis 
exposed beneath; leaves oval, obtuse, pubescent (especially beneath); peti- 
oles 2-4” long; spiny branches 4-1’ long, thick, terminating abruptly in 
a point. More or less leafy; flowers greenish. Valley of the Gila, Ari- 
zona, at 3,080 feet altitude. (331.) 
Karwinskia t+ Humpoupriana, Zuce. (Gray, Pl. Wright. 1, p. 32).— 
Shrub from 2—12° high, leaves oval and beautifully penninerved [Flow- 
ers not seen.}] Drupe ovoid, 4—5’’ long, pointed with the remains of the 
style, cup or disk-like calyx terminating the pedicel after the drupe has 
fallen. Plant appears to vary much in the shape of the leaves and in the 
number of flowers in the axillary clusters. Arizona.

* ZizyPuus, Juss.—Calyx 5-cleft, tube broadly obconical, lobes triangular-ovate, acute, spreading, 
carinate within. Petals 5 (rarely 0), hooded, deflexed. Disk flat, 5-angled, margin free Stamens 
5, included or longer than the petals, filaments subulate. Ovary immersed in the disk and at the base 
confluent with it, 2-, rarely 3-, most rarely 4-celled; styles 2-3, conical, free or connate, divergent, 
stigmas small, papillose. Drupe fleshy, globose or oblong, putamen woody or bony, 1-3-celled, 1-3- 
seeded. Seeds plano-convex, testa thin, fragile, and smooth, albumen little or none; cotyledons thick ; 
radicle short.—Shrubs or trees decumbent, or with many small branches, often with strong, hooked 
spines. Leaves sub-distichous, alternate, petiolate, coriaceous, entire or crenate, 3-5-nerved. Stipules 
both spinescent or one caducous, hooked or straight, cymes short, axillary, few-flowered. Flowers small, 
greenish. Ski) often er Rg mse & Hooker. 
ec.—Calyx 5-cleft, tube hemispherical or turbinate, acute lobes 3-angled, keeled 
or with ‘ic hed pas within and above into aspur. Petals 5, short-clawed and hooded. Stamens 
longer than the petals, filaments subulate. Disk lining the tube of the calyx, delicate limb free. Ovar 
sub-globose, immersed in the disk, fr.e, 2-3-celled, septa parting in the middle, often attenuated (the 
ovary) into a triangular style, with the apex 2-3-lobed, stigmas obtuse, papillose; ovules 2 in each cell, 
parallel, curved downward. Drupe sub-globose or ovoid, apiculate with the persistent style, surrounded 
at base by the calyx, putamen 1-2-celled, each cell 1-seeded. Seeds erect, obovate, testa membranous 
dark-verrucose, raphe elevated, albumen in a thin fleshy stratum adherent to the testa; cotyledons pat, 
fleshy; radicle very short.—Small trees and shrubs. Leaves sub-opposite, petiolate, oblong, entire, 
penninerved, pellucidly panctulate. Stipules membranous, deciduous. Flowers axillary, racemose or 
ceymose. Cymes fasciculate.—BENTHAM & HOOKER.
