322 BOTANY. 



but rather to be referred to the former, having a similar though smaller leaf, 

 (3-5' long,) with 3-4 pairs of rather narrow oblong subequal lobes, opposite 

 or alternate, obtuse and subentire, with no tendency toward the fewer 

 rounded divergent unequal lobes that characterize the leaf of stellata, yet 

 with much of its yellowish downy pubescence, only occasionally becoming 

 nearly glabrous ; it has also the glabrous anther of alba, (though otherwise 

 described by De Candolle,) the longer peduncle, the same proportioned 

 shallower cup, 4-7" (usually 5") broad and 3" deep, with convex inflated 

 scales ; the acorn is considerably smaller than that of alba, usually 9" long 

 and 5" in diameter, sometimes much shorter and scarcely exserted from the 

 cup. Usually low and scrubby, covering the foot-hills, but at times attain- 

 ing I-IP in diameter and 20° in height, with the bark and all the habit of 

 Q. alba. 515 Hall & Harbour, referred to Q. Douglasii, Var. Nova Mexicana, 

 is the same. Not seen west of the Wahsatch, but extending east to Colo- 

 rado and south to latitude 38° ; 5-7,000 feet altitude. (1,086.) 



Castanopsis^ cheysophylla, a. DC. Prodr. 16. 2. 109. {Castanea, 

 Hook.) Leaves 4-5' long, evergreen, broadly lanceolate, acuminate, acute 

 at base, entire, coriaceous, deep-green and glabrous above, the younger ones 

 especially covered beneath with golden-yellow scales ; stipules ovate-lance- 

 olate, caducous ; aments densely flowered, half shorter than the leaves ; styles 

 3, erect and subdivergent, glabrous, linear ; fruit crowded, densely prickly. — 

 A tree of Oregon and California, becoming 60-100° high, and 1-3° in diam- 

 eter. Var. MiNOE, Benth. A shrub 2-6° high, with smaller leaves, 1-2 J' 

 long, 6-9" wide, often obtuse, and acute or obtuse at base, on petioles 3 6" 

 in length. Stipules subpersistent, 1" long ; aments pubescent, with the 

 small lanceolate bracts sometimes hidden between the fascicles ; spikes 

 androgynous, the fertile flowers surrounded by broad ovate bracts and scales ; 

 calyx pubescent except at base, lobes ovate, doubly serrate ; stamens often 

 abortive ; scales of the finally dehiscent involucre becoming elongated (some- 



1 CASTANOPSIS, Spach. Sterile flowers fascicled, surrounded by bracts, in an ameut. Calyx 

 regularly 5-6-lobed. Stamens usually twice as many as the lobes ; filaments slender, elongated ; anthers 

 very small, 2-celled. Eudimentary pistil globose, free, hirsute. Fertile flowers 3-1, in a scaly involucre. 

 Calyx 6-parted, lobes obtuse, in two rows. Styles 3, (rarely 3-5,) linear, opposite the outer calyx-lobes. 

 Ovary 3-ceUed ; cells 2-ovuled ; ovules amphitropous from the lower angle. Fruit consisting of the 

 involucre and 3-1 included cartilaginous free nutlets ; involucre globose, beset with usually branched 

 prickles growing tardily from the scales, rarely crested with subcorneal tubercles, closed, at length irreg- 

 ularly cleft or indehisceut. Seeds by abortion solitary ; cotyledons thick, mealy, plano-convex ; radicle 

 superior.— Trees of Asia and California, with the habit and inflorescence of some Asiatic sections of 

 QitercHS and the fruit of CaiHrna, but the ovary 3-celled ; fruit maturing the second year.
