west and south-west of Ta-tsien-lu, from 3300—4000 m. 
above sea-level, are 3,5—3,7 cms. long. WILLIAM PURDOM’s 
No. 760 from the south of Kansu, 3000—3300 m. above 
sea-level, should be mentioned 
as representing material from a 
northern locality; six cones from 
this collection vary from 3 to 
3,5 cms. in length. REHDER & 
WILSON estimate the average 
length of the cones taken from 
the intermediate and most 
northern localities to be 3—4,5 
cms. (Pl. Wils. 1916, p. 19), but 
specimens from more southerly 
regions show that it can be 
considerably greater. Among

the Likiang Range in the extreme 
5 cms. in length (Kew Herb.), and Rock's specimens from 
the same neighbourhood (1922—24) are, according to 
REHDER, 6—7 cms. long (Journ. Arnold Arb. VII, 1926, 
p- 46. See also f. australis Henry apud Handel-Mazzetti, 
1929, |. c.). In this connection it should be stated, that 
FRANCHET had already described this species from Yunnan, 
and this accounts for his quoting a length as great as 
5 cms. for ordinary cones (R. P. DELAwAy). The large 
cones, which demonstrably exist, give it a point of simila- 
rity with L. Griffithiana, and explain the reason for MASTERS 
and PATSCHKE attributing this species to Szechuan on the
