" The typical form of L. principis rupprechtii as represented by 

 the specimens from Wutaishan (collected by Purdom and Meyer) 

 looks quite distinct from typical L. dahurica, but the specimens from 

 Weichang, together with others from Manchuria, Amurland, and 

 Korea, form a series which gradually merge into typical L. dahurica. 

 With L. sibirica Ledebour, with which it has been compared, it 

 agrees only in the size of its cones, but differs in their perfectly 

 glabrous, more spreading, and thinner scales not incurved on the 

 margin, truncate, or (particularly in the Weichang specimens) even 

 emarginate at the apex, and in the more conspicuous bracts which 

 are often, particularly in the lower part of the cone, more than half 

 as long as the scales ; in all these characters L. principis rupprechtii 

 agrees with L. dahurica, and it seems therefore best to consider it 

 a variety of this species, distinguished by the more numerous scales. 

 Purdom and also Meyer speak of this larch as forming forests on the 

 northern slopes of Wutaishan and in its neighborhood where, accord- 

 ing to Meyer, the snow does not melt until well into May. In the 

 Weichang region Purdom remarks that the tree is now becoming 

 very scarce." (Rehder and Wilson, Plantae Wilsonianae, vol. 2, 

 p. 21, 1914.) 



39996. Picea koyamai Shirasawa. Pinacese. Spruce. 

 Wilson No. 7528. 



A small, cone-shaped Japanese spruce, up to 10 m. (32£ feet) high; 

 the trunk reaches a diameter of 25 cm. (10 inches). The young trees 

 present an appearance similar to those of P. excelsa. Young twigs red- 

 dish brown, smooth ; buds cone shaped, short ; scales brown, covered 

 with resin; needles short, thick, obtuse, four sided, standing thickly and 

 obliquely on the twigs ; straight or often somewhat bowed, 7 to 13 mm. 

 (one-fourth to one-half inch) long, seeming blue- white from a distance. 

 Cones elliptic oval, obtuse, brownish yellow-green, 3.5 to 6 cm. (1.4 to 2.4 

 inches) long, 2.5 cm. (1 inch) broad. (Adapted from H. Shirasawa, 

 Mitteilungen der Deutschen Dendrologischen Gesellschaft, p. 254, 101 4-^

39998. Viburnum furcatum Blume. Caprifoliaceae. 

 Wilson No. 7624. 



"A native of Japan and China. This also has the showy sterile margi- 

 nal flowers, but its stems are more uniformly erect. It differs also in the 

 shorter stamens, which are only half the length of the corolla, and in the 

 shape of the furrow in the seed. It succeeds in gardens no better than 

 V. alnifolium, although there was a healthy plant at Abbotsbury, near 

 Weymouth, a few years ago. It is a native of northern Japan at low 

 levels and of the mountainous parts of the south. The foliage turns 

 brilliant scarlet to reddish purple in autumn. It is a bush 12 or more 

 feet high in a wild state." (W.J. Bean, Trees and Shrubs Hardy in the 

 British Isles, vol, 2, p. 642.)
