The Species of the Genus Larix. 11 
L. Griffithiana was discovered in 1838, but it was not 
described in detail until its re-discovery by HOOKER in 1848, 
who thereupon introduced it into England. Hooker found 
it only as a small tree, 6—18 m. in height, in the west of 
Nepal, and it never becomes a tall tree, even although a 
rather greater height, 19,5 m., has subsequently been 
reported for specimens in Sikkim, and those found in the 
Chumbi valley, one of the most recently discovered locali- 
ies, are possibly a trifle taller still. A tree cultivated at 
Coldrennick in Cornwall is quoted as being 23,5 m. high, 
and as such is taller than any noted in their natural 
haunts. (Gard. Chron. XLI. 1907, p. 130; DALLIMORE & 
JACKSON, 1923, p. 287). 
According to I. D. HookeEr’s drawing of a tree in its 
native habitat in Sikkim (Fig. 1), the crown is broader, the 
branches differently arranged, and the branchlets longer 
and more pendulous than in the case of L. decidua, and 
Hooker also compares it with L. decidua var. pendula 
(Gard. Chron. XXV. 1886, p. 719). It differs from most of 
the other members of the genus Larix in possessing cones 
of great size, reported by Hooker as being 5—7,5 cms. 
long (Fl. Brit. Ind. V. 1890, p. 655). REGEL (1871; fig. 2 in 
present paper; same fig. in BEISSNER, 1909) has an illustra- 
tion of a cone nearly 9 cms. long, and three cones from 
the already-mentioned tree in Cornwall are between 10 
and 11 cms. in length. It is probable that the cones from 
cultivated specimens have a tendency to become larger 
than they would be in nature, and when DALLIMORE & 
Jackson (1923, p. 286) state the size as being 5—10 cms. 
long, these figures perhaps include specimens from both 
cultivated and wild individuals. 
The bracts are longer than the cone-scales, the same 
being the case with L. Mastersiana, L. Potanini, L. Lyallii,
