WILSON EXPEDITION TO CHINA 



larum liberis plerumque rotundis vix prominulis notatus, ater, epruinosus, niti- 

 dulus; semen ovoideura, apicem versus compressum, obtusum, 4-5 mm. longum. 



Kansu: Peling-shan, alt. 3300-3600 m., 1911, W. Purdom. North-western 

 Szech'uan: mountains to north of Sungpan Ting, alt. 3600-4000 m., September 

 1904 (Veitch Exped. No. 3013). 



This new tree Juniper is very distinct in appearance and is easily recognized by 

 its clear, deep green, scale-like leaves and the very small, erect, shining black one- 

 seeded fruit. It is most closely related to J. pseudo-sabina Fischer & Meyer, which 

 is a shrub and is distinguished by its more pronounced dimorphic leaves, and by 

 its much larger, ovoid to oblong, recurved, smooth fruit. Juniperus Wallichiana 

 Hooker f. & Thomson apud Brandis, which is usually regarded to be the same as 

 J. pseudo-sabina Fischer & Meyer, agrees with our new species in habit and in 

 having the fruit erect, but is at once distinguished by the very large size of the fruit 

 which is from 2 to 3 times as large as that of J. saltuaria and quite smooth. The 

 leaves also differ, resembling more closely the typical plant of Fischer & Meyer 

 than the species here described. Possibly these three Junipers represent geograph- 

 ical varieties or forms of one polymorphic species, but until our knowledge con- 

 cerning them is more complete, it appears to us best to keep them as distinct. 



Round Sungpan Ting /. saltuaria forms extensive woods and the wood, though 

 of no great size, is highly valued for construction purposes, and most of the houses 

 in the city of Sungpan are built of it. The habit of the tree is very shapely and 

 pyramidal and the branching is very dense, although in very old trees the habit 

 becomes more loose and irregular. There is no information with Purdom's speci- 

 mens, but from the abundance of material sent it is probably a common tree on 

 the Peling-shan. The Juniper collected on the mountains of the Kukunor region 

 and near the upper sources of the Hoang-Ho, by Przewalski, and referred (Bret- 

 schneider. Hist. Europ. Bot. Discoveries in China, 987) to J . pseudo-sabina, very 

 probably belongs to our new species. Our No. 3013 has been referred by Masters 

 {Jour. Linn. Soc. XXXVII. 412 [1906]) to the very different J. chinensis Linnaeus.

Western Szech'uan: without precise locality, arid places, alt. 2500 m., 

 August 1904 (Veitch Exped. No. 3010). 



A well-marked species not closely related to any Asiatic Juniper, and readily dis- 

 tinguished by its shining, chestnut-brown, decurved one-seeded fruit. In habit 

 and appearance it somewhat resembles J. excelsa Bieberstein, but this has much 

 larger, glaucous-black, 2-5-seeded, erect fruit. It may also be compared with J. 

 saltuaria Rehder & Wilson which has more or less 4-sided branchlets, slightly 

 keeled leaves with inconspicuous dorsal gland and small, erect, jet-black fruit. 

 Juniperus convallium is apparently a rare tree and, as far as our knowledge goes, 

 is confined to the warm and more arid parts of the principal river valleys of the 

 Chino-Thibetan borderland. The tree is very Cypress-like in appearance and is 

 frequently very glaucous. Dr. Masters (in Jour. Linn. Soc. XXXVII. 412 [1906]) 

 referred this number to the entirely different J, chinensis Linnaeus.
