Coaz can only be understood to mean, that he believes 
he has observed the cross L. Kaempferi X decidua; but 
others are of the opinion that it is L. Kaempferi X sibi- 
rica (HENRY & FLoop: l.c. p. 57; vide HENRy’s notes: 
ibid. p. 66; DALLIMORE & JACKSON: 1. c. p. 292). Coaz’s 
observations are based upon specimens of seed from a 
L. Kaempferi in the neighbourhood of Morat in Swit- 
zerland. L. decidua and L. sibirica were both found 
close by, but, as already stated, Coaz believes the European 
Larch to be the male parent in the supposed cross; it 
seems, nevertheless, as though there might be some doubt 
as to whether it was the one or the other. If, however, 
any regard is to be paid to his observations, it can only 
be in the present shape; perhaps it would be best to neg- 
lect them entirely. 
The oldest specimens of the hybrid L. Kaempferi x decidua 
recognised with certainty originated about 1900 upon the 
estates of Dunkeld and Murthly in Perthshire, Scotland, 
and the first detailed report by Henry & FLoop in 1919 
was based upon material derived from this source. 
It is an easily recognisable form, intermediate between 
the two widely different parent trees. The cone is more 
cylindrical than that of L. Kaempferi, the cone-scales being 
at the same time less recurved. The one-year shoots are
