PINACEAE. — PSEUDOLARIX 21 



terminated. It is now in cultivation at the Arnold Arboretum and is in other 

 collections. 



A picture of this tree will be found under No. 126 in Wilson^s collection of 

 photographs and in his Vegetation of Western China, No. 281. 



Here may be added a note on a variety of L. dahurica Turczaninow collected in 

 Shansi by W. Purdom and by F. N. Meyer. 



Larix dahurica Turczaninow, var. Principis Rupprechtii Rehder & Wilson, n. var.

Shansi: Wutai village, around temples, 1909, W. Purdom (Nos. 161, 161% 

 161**); Wutaishan, over the pass, alt. 2600-3000 m., 1909, W. Purdom; without 

 precise locahty, alt. 2000 m., 1910, W. Purdom; Wutai-shan, " Tshai-Iing-tse " 

 temple, February 25, 1908, F. N. Meyer (No. 22674). Chili: Weichang, 1909, 

 W. Purdom (No. 21; tree 20-25 m. tall, girth 2 m.), Weichang north and west, 



1909, W. Purdom (Nos. 204, 246). 



The typical form of L. Principis Rupprechtii Mayr as represented by the spec- 

 imens from Wutai-shan looks quite distinct from typical L. dahurica, but the spec- 

 imens from Weichang, together with others from Manchuria, Amurland and 

 Korea form a series which gradually merge into typical L. dahurica. With L. si- 

 birica 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 form- 

 ing forests on the northern slopes of Wutai-shan and in its neighbourhood where, 

 according to Meyer, the snow does not melt until well into May. In the Wei- 

 chang region Purdom remarks that this tree is now becoming very scarce. 



We are not able to distinguish from typical L. dahurica the L. Cajanderi Mayr 

 {Fremdl Wald- w. Parkh. 297, fig. 88 (1906)).
