gnarled stems are very strong, and the smooth, mottled 
gray bark is about like holly bark. 
"The plant takes kindly to pruning, as shown 
by those bushes growing along trails where sheep and 
goats have kept them trimmed back. It Is hardy in a 
climate much like that of Washington, D. C, and is 
unaffected by temperatures of 0° to 110° P. These 
seeds were collected in Thrace, near the base of the 
ftalllpoli Peninsula, where the plant is very common; 
It has a vertical range from sea level to 3,000 feet, 
the highest mountains in the district where it Is 
found. The tree is adapted to a wide variety of soils, 
growing vigorously in beach sand, lowland silts, re- 
sidual sandy and clayey soils, and on rocky surfaces 
wit h little sol 1. 
"The bush grows to a height of 6 to 10 feet. I 
saw one individual, probably of the . same species, that 
had a trunk 8 Inches In diameter and was 20 feet high.

covered by Delavay In Yunnan, China, at an altitude 
of about 9,000 feet. It has small, pink, sweet-scented 
flowers which are produced when the plants are still 
small enough to be handled in pots. It is said to be 
perfectly hardy in England." (F. V. Coville.)

Mr. J. F. Rock writes January 22, 1921: 
"I am writing you from the heart of the Burmese 
jungle of the Northwest. For four days I have roamed 
the forests in search of ripe fruits of Hydnoea r pus kurzii, 
but in vain until now. I have followed the Khodan 
stream, a tributary of the upper Chlndwln River, ,f or 
about 60 miles, and at present I am camping in a 
jungle village. The jungle is so dense that it lg !m<- 
possible to penetrate far, but by following sandy 
streambeds, which are dry at this time, I succeeded
