THE CONIFERS OF CHINA, 417 
transverse oblongus demum reflexus ; umbo rhomboideus parum 
depressus deltoideo-mucronatus ; muerone caduco. 
Cura occrp., in silvis prope vallem Ya Lung ad alt. 9000- 
11,000 ped. (Wilson 3015 !). 
A species, according to Mr. Wilson, resembling the Scots Pine 
in general aspect and growing in forests at a higher altitude than 
any other Pine met with by him. The wood is used for making 
torches. It bears a close resemblance to P. densiflora, but differs 
especially in the thickened cushion-like apophyses. The resin- 
canals are mostly subepidermal, but, as in P. densiflora, some 
are occasionally found in the substance of the leaf, especially 
near the corners. 
Pinus prominens, Mast., sp. n. Arbor 25-ped.; ramis fuscis 
glabrescentibus, pulvinis late oblongo-obovatis dorso medio in- 
crassatis. Novelli glabri aurantiaci, pulvinis parum prominentibus 
superne ad marginem eversis. Gemme ovoidee in mucronem 
fastigate. Peruleé subcoriacee, ferruginez, lanceolate acutatæ 
ad margines albidas lacerato-membranacee. Vagine ad 2 cent. 
long., squamis arcte convolutis membranaceis transverse sulcatis 
sursum increscentibus. Folia bina linearia 10-14 cent. dorso 
convexa, facie antica concava, apice cartilagineo-mucronata, 
marginibus obsolete serrulatis. Canales resiniferi numerosi 
subepidermide positi; meristela elliptica, fasciculus vasorum 
bifurcatus. Amenta mascula . Strobili sessiles patentes 4-5 
cent. long.,3 cent. lat., oblongi, basi apiceque angustati, maturitate 
squamis expansis ovoideo-subglobosi. Squame lignose. Apo- 
physis elavato-dilatatus, umbo prominens deflexo-assurgens 
rhomboideus apice subulato mueronatus. 
Curna occ. versus Tu-chu-lu (Wilson 3016 !). 
Allied to P. densiflora and to P. densata, but distinguishable 
by its buds, its cones and prominent umbos.
