340 A HANDBOOK OF CONIFERiE 



King, who sent seeds to Europe about 1878. Very few trees are 

 known in the British Isles, and it appears to be more tender than 

 P. Morinda. There a.re good specimens at Castlewellan, 

 Leonardslee, Menabilly and Chetley Place, Liphook ; but in 

 some places it has possibly been passed over for P. Morinda, 

 which it much resembles in habit and with which it was formerly 

 confused. 



Wood very similar in appearance to that of P. Morinda, but 

 said to be harder and heavier. 



If seeds were obtained from a high elevation, the resulting 

 plants would probably be hardier than those now growing in this 

 country. At present it is found to give the best results in the 

 warmer parts of the country, where the soil is good and moist.

Picea morrisonicola, Hayata. 



A Formosan species found on Mount Morrison by Torrii in 

 1900. It is described as having glabrous shoots. Buds ovoid 

 conic, with ovoid, obtuse, scarious scales. Leaves linear, four-sided, 

 |-| in. long, apex acute, stomatiferous. Cones oblong-cylindric, 

 2 in. or more long, deflexed ; scales ovate-orbicular, tapering 

 at the base, rounded-truncate and sub-entire at the apex. Seed 

 with a wing 1 cm. long. 



iUUed to P. Glehni but differs from it in having non-hairy 

 shoots.

A tree attaining in N. America a height of 50-75 ft. and a girth 

 of 6-9 ft., but often of much smaller dimensions. Bark reddish 

 brown, scaly. Young shoots brownish, with short, dense, glandu- 

 lar hairs. Buds ovoid, surrounded by awl-shaped, fringed scales. 

 Leaves arranged like those of the common spruce, crowded, bluish 

 or glaucous green, about ^ in. long, quadrangular in section, 

 ending in a horny point, with 1-4 lines of stomata on each side. 

 Cones persisting several years after shedding the seed, ovoid, 

 short-stalked, about 1 in. long, green tinged with purple or deep 

 purple when growing, reddish brown when ripe ; scales broadly 

 ovate or rounded, with toothed margins. Seeds ^ in. long, with 

 pale brown wings ^ in. long.
