PLANT MATERIAL INTRODUCED 



89694 to 89698 — Continued. 



89695. QUERCUS MONGOLICA FiSCh. 



Mongolian oak. 



No. 7181. From the Fa Hua Ssu 



Temple, September 16, 1930. Seeds of 

 a handsome oak which becomes 100 

 feet tall. The short-stemmed, dark- 

 green, coarsely toothed, fairly broad 

 leaves, 6 to 8 inches long, are crowded 

 toward the ends of the twigs. 



For previous introduction see 85025. 



89696. Quercus dentata Thunb. 



Daimyo oak. 



No. 7196. Collected September 17, 

 1930, in the mountains west of Fa 

 Hua Ssu Temple. 



For previous introduction and de- 

 scription see 89605. 



89697. Quercus dentata Thunb. 



Daimyo oak. 



No. 7229. From Nankou, September 

 19, 1930. Acorns of broad-leaved oaks 

 from trees growing in abundance at 

 Changling (Yung Lo Ming Tomb). A 

 most beautiful oak with large shining 

 green leaves which in the fall turn 

 to warm red hues. It is a slow grow- 

 er, but well worth wbile. 



89698. Quercus acutissima Carruth- 

 ers. Bristletooth oak. 



No. 7230. From the Yung Ling 

 Ming Tomb, Nankou, September 19, 

 1930. Acorns from two young trees 

 with narrow, attractive, bright-green 

 leaves. The cups and acorns of this 

 narrow-leaved oak are quite different 

 from those at the Fa Hua Ssu Temple 

 or on the hills at Patachu, from both 

 of which places seed has been secured. 



89699 to 89719. 



From Chiddingfold, Surrey, England. 

 Plants purchased from V. N. Gauntlett 

 & Co. (Ltd.). Received November 7, 

 1930. 



89699. Arundinaria anceps Mitf. Poa- 

 ceae. Bamboo. 



The botanical name of this attractive 

 bamboo means the doubtful arundinaria, 

 referring to an uncertainty as to its 

 origin. It is now believed to have come 

 from northeastern India. The culms are 

 round and slender and are reported to 

 grow 10 to 15 feet high in England. On 

 small plants there are two or three 

 branches at each node, with rather long 

 branchlets, having 8 to 10 linear-lanceo- 

 late leaves. The leaves are light green 

 and up to 3% inches by % inch in size. 

 The auricular hairs on the leaf sheaths, 

 although not conspicuous, are unusually 

 persistent. The secondary veins are 

 three or four on each side of the midrib, 

 with four to seven intermediates be- 

 tween. The tessellation (cross venation) 

 is minute and unusually regular. 



89700. Arundinaria hindsii graminea 

 Mitf. Poaceae. Bamboo. 



This variety of Arundinaria hindsii 

 does not grow so tall as the type, but 

 will probably reach 8 feet or more. The 

 dark-green leaves are very narrow, and 

 small ones often have only one or two 

 pairs of secondary veins. There are 

 three to four intermediate veins. The 

 leaves may reach a length of 9 inches 

 with a width of one-half inch. 



to 89719 — Continued. 



89701. Phvllostachys bambusoides cas- 

 tilloni (Marl.) H. de Lehaie. Poa- 

 ceae. Castillon bamboo. 



A smaller and more slender Japanese 

 form of Phyllostachys bambusoides with 

 yellow stems striped with green and the 

 shorter and narrower leaves often striped 

 with yellow. It grows to a height of 

 35 feet or more. As in the type, the 

 rhizomes are vigorous and spread rapidly. 



For previous introduction see 75155. 



89702 to 89704. Arundinaria spp. Poa- 

 ceae. Bamboo. 



89702. Arundinaria murielae Gamble. 



A handsome bamboo understood to 

 grow to a height or 10 to 15 feet. It 

 is reported to produce dense masses 

 of culms, which is unusual for hardy 

 bamboos. The culms turn to a rich 

 yellow with age, and there are one to 

 many branches at the nodes. On small 

 plants the branches bear two to three 

 leaves up to 2% inches long by T V of 

 an inch wide. There are usually three 

 pairs of secondary veins, and the inter- 

 mediates are five to eight. The tessel- 

 lation is rather close. 



89703. Arundinaria nepalensis Hort. 



A small plant of this bamboo has 

 six to seven leaves on a branch. The 

 leaves are up to 3 inches long by % of 

 an inch wide and rather thin. There 

 are two to three secondary veins, and 

 five to six intermediates. The cross 

 veinlets are unusually far apart. 



89704. Arundinaria nitia Mitf. 



The plant received under this name 

 does not agree well with the original 

 description. The most striking point 

 of difference is that in the plant re- 

 ceived the secondary veins, of which 

 there are three pairs, are prominent 

 instead of being nearly indistinguish- 

 able from the intermediates. There 

 are six of the latter. The leaves are 

 light green, four to six on a branch, 

 and, in size, up to 2% by % inch. The 

 tessellation is close and regular. The 

 culm sheaths are rather persistent. 

 The species is reported to reach a 

 height of 15 feet in England. It pre- 

 fers shade. 



For previous introduction see 75150. 



89705. Sasa veitchii (Carr.) Rehder. 

 Poaceae. Bamboo. 



Received as Arundinaria senanensis. 

 The description and illustration of this 

 bamboo in the catalogue of Gauntlett & 

 Co. agree with those elsewhere of Sasa 

 veitchii. Some authorities have believed 

 Arundinaria (Sasa) senanensis to be the 

 same as S. veitchii, but others consider 

 them to be distinct species. On a green- 

 house plant 10 inches high the leaves are 

 up to 4 by 1% inches and there are five 

 to seven pairs of secondary veins with 

 about seven intermediates. The decayed 

 or whitish margins which are charac- 

 teristic of S. veitchii do not appear on 

 this greenhouse specimen. 



89706. Arundinaria spathiflora Trin. 

 Poaceae. Bamboo. 



A bamboo native to the northwestern 

 Himalayas, said to grow 20 to 25 feet 

 high. In England it has reached 10 feet. 

 The small plant received has only three 

 or four branches at each node, but 

 mature plants are stated to have many 

 branches. The thin delicate leaves are
