56677. CASTANEA sp. According to Mr. Rock this is a fine tree, 
growing 60 to 100 feet high with trunks 4 to 5 feet in diameter. The 
ours occur in spikes and the nuts are small and sweet, something like 
a chinquapin. The leaves are obovate, about 3 inches long and l£ 
inches wide. They taper rather abruptly at the base and have a rounded 
apex. The margins are coarsely sinuate. The veins on the lower sur- 
face are prominent, 
56768. castanea sp. This is a fine lofty tree 80 to 100 feet 
high with a trunk 3 feet in diameter. According to Mr. Rock, the 
smooth, fawn-colored bark is flaky, and the straight, ascending branch- 
es give the tree an oblong appearance. It is said to be one of the 
finest forest trees of the region. It is found at an altitude of 6,000 
feet. The nuts are small, resembling those of the chinquapin. In the 
seedling stage the leaves of this chestnut resemble very closely those 
of S.P.I. No. 56130. They are lanceolate, 3 to 5 inches long and about 
one inch wide at the widest part. The edges are smooth, base broadly 
tapering, apex narrow and long. 
56777. castanea sp. This is another small-fruited Castanea with 
more or less triangular nuts. It was collected November 12, 1922, and 
received January 18, 1923. There is no information as to the size and 
character of the tree. The leaves of the seedlings are small, 1 to l£ 
inches long, light green above and below, lanceolate with faintly sinuate 
edges . 
56296. castanopsis sp. A tree growing 70 to 80 feet in height. 
The nuts were collected on the slopes of the Likiang Snow Range at an 
altitude of 10,000 feet. Collections were made in October, 1922, and 
received in Washington February 2, 1923. The nuts are small, resemb- 
ling small acorns; they are said to be sweet and edible. 
56297. CASTANOPSIS sp. According to Mr. Rock, this is one of the 
finest and largest species of Castanopsis in Yunnan Province. It 
reaches a height of 80 feet and has a diameter of 2 to 3 feet. The 
nuts were collected at an altitude of 8,000 feet. It is a fine timber 
tree, free from disease. Mr. Rock's collections were made in November, 
1922, and were received in Washington February 2, 1923. The nuts are 
quite small, resembling small acorns, and are edible and sweet. 
56300. castanopsis sp. A tree 60 to 80 feet high with a trunk 2 
to 3 feet in diameter, found at altitudes of 7,000 to 8,000 feet. The 
nuts are small, more or less triangular and flattened. They were col- 
lected in November, 1922, and received in Washington February 2, 1923. 
According to Mr. Rock the nuts are sweet. 
56489. castanopsis sp. This is a fine tree growing 60 to 80 feet 
tall with a straight trunk 2 to 3 feet in diameter. The nuts were 
collected at an altitude of about 7,000 feet. They closely resemble 
small chestnuts, being at first brown, then becoming black. They are 
also sweet and edible. The genera Castanopsis and Castanea are closely 
allied and differ chiefly in their flowers.
