Mr. Gilchrist cannot give these problems any of 
his time and has turned over the whole thing to 
rae. 
Later on I v;lll v/rite more on this subject, 
but it v/ill suffice to say that Citrus ichan/^ensls 
is like the Yang tao,- it is not very hardy. Al- 
tho' one finds it at 4000 ft. a.s. one finds coir 
palms, pummeloes, loquats, candle-berry trees, 
lucidum privets, tall bamboos in gardens nearby. 
These high altitudes in a very mountainous country 
» are misleading,- it is not as cold there as further 
south in level regions. 
Mr. Swingle wants a large quantity of seeds 
for stock purposes. Well, I may come across 
great masses yet, but as far as I have seen al- 
ready this wild Citrus ichangensis is decidedly 
a rare plant: To get large quantities of seeds 
we shall have to grow them ourselves in the 
United States. Parts of Texas might suit this 
plant well and I suggest to Mr. Swingle to have 
arrangements made to set out a few groves far 
away from any other citrus trees, 
I discovered today that a true citron is be- 
ing cultivated around here. It is quite rare and 
I think it might have been introduced from abroad. 
The large ribbed fruit is delightfully fragrant, 
and the strawberry-like odor of a basket of Yang 
taos, the pungent aroma of a few cultivated Ichang 
lemons, the spicy-sweet scent of this citron, and 
the bitter-aromatic exhalation of a very large 
pummelo, make my room like a bed of "waldmeister " 
( Asperula odor at a) on a fresh morning in May. 
Tomorrow we shall leave for a high mountain 
l-l/? days N. W, from here, the ¥/an tiao shan, 
elev. 8100 ft. a.s. v^ere Wilson found Davidia 
involucrata , Tetracentron sinensis and many more 
interesting iDlants. Then I'll go to Patung on 
the Yang tze and from there to the S.E. over 
Chang yang back to Ichang v/here I'll find a 
goodly stack of mail, I surmise. Then I must 
go back to King men for pear and pistache seeds, 
- then thip them off from Hankow, then I may go 
by boat to Kiukiang, walk to Poochow in Fookien, 
and from there take a boat to Canton and later 
on to Manila. 
The seed of Citrus ichangensis, Meyer's No. 2455a, was given 
SPI No. 45945, and his No. ?456a, the smooth variety of 
Actinidia chinensis, SPI No. 45946. This material reached 
December 31, 191?.
