My opinion is there are two kin species growing in Turkestan--Juglans regia L and J fallasc Dode; the first in the Kopet-Dag, the second in the Fansha mountains, in guissar and Darwas. The J. regia is further cultivated in Turkestan gardens and in the Lowawschan Valley. The J. Kamaonia Dode is occasionally to be observed likewise in gardens. I did not chance to see it personally and am in possession of only one of its nuts. Both species (the J. regia and the J. fallasc) produce a great variety of nuts as to shape, thickness of shell and size of kernel. Both these species have been united by some authors (Mr. M. Popof in Bull. of Applied Botany of Genetics and plant breeding XXII N3 (1929), p. 294) into one--that of J. regia but always distinguishing the Kopet-dog nuts in the jsp. turcomanica Popof; difference between them being certainly esctant. The number of leaflets of the J. fallasc amounts to 2-4, they are rounder and more obtuse, the shell of the nut is thicker and also rounder and smaller. The number of J. regia leaflets is 3-5, they are narrower and more pointed (lance shaped), the nuts more elongated, larger and their shell thinner.

Having been for my part mainly occupied with the geographical distribution of nuts without regard to the variation of the fruit shape, I would recommend you to apply for a choice of nuts to Mr. Gursey, (Caucasus, Pjabigorsx), who is making a special study of the problem.

For cultivation in the north you will be interested in J. Manshurica originating in the Far East and very hardy. It is cultivated and produces fruit in Leningrad, young specimens of it were planted on the Solovetsky Islands in the White Sea and there outlived excellently.

Concerning the list of trees appended to your letter, I can give you the following information.

Northern Nut Growers Association Report of the Proceedings at the Twenty-Fifth Annual Meeting — Part 126

_J. Regia_ grows well in the park of Botanic Institute in Leningrad, attaining 8-10 M.; in the southern part of Smolensk district the tree produces fruit as far as Minsk. There is a considerable number of fruit producing specimens in the Masir district in the north of White Russia.

_J. Sieboldiana_ freezes up in cold winters in Leningrad.

_J. cinerea_ is very hardy and effects self-polinasation in White Russia; near Kasan there is one specimen producing about 100 fruits yearly.
