There has been considerable misconception in regard to the distribution of this species. Under
L. cr^piihium in the PI. Br. I n d . v, 740, Sir Joseph Hooker remarks. " A specimen in Hort. Kew,
marked 'Garhwál, Falcouer,' is perhaps a cultivated one." This evidently refers to the two
specimens of D. crepidaium glued down on the same sheet with Falconer's specimens of D. primuUnum,
and all of them named D. cretacenm on the Kew Distrib. ticket No. 1005 by Reichenbach f.
subsequently. There is also on the same sheet an original ticket of Falconer's r e f e r r i n g to t h e specimens
of D. primuUnum, and hearing the manuscript namo of ' D. pstfOC^rpwH. Both J), pfifnulinion and
B. crepidatum were ioxind by Falconer in Garhwál, and they were no doubt cultivated in the
Saharanpui Garden, and sent thence to Kew under one name. The supposition that D. primuUnum
•was ever found wild in Sikkim is probably an eiTor.
