512 Materials for a Flora of the Malayan Peninsula. 



There is a large suite of specimens of this species in tlie Calcutfa 

 Herbarium (twelve gatherings from the A.tidaraans alone). I have 

 dissected flowers- of every one of these which is in flower, and I find that 

 tliej all agree perfectly with each other. They also agree absolutely with 

 Heifer's specimen, No. 1131. With the phmt collected in Perak by the 

 Bot. Garden Collector (No. 744'2) they also ns to flowers and leaves 

 (fruit is absent) agree, except that the Perak plant has slightly larger 

 flowers and that the calyx-lobes are longer and more acute. Heifer's 

 specimen above quoted has, however, been referred by Dr. Engler, in 

 bis excellent raonogivaph of the family of Anacardiacras^ to Seme- 

 carpus albescens, Kurz. To that identification I must, with all res- 

 pect, demur. Moreover an examination of the large suite of specimens 

 of S. albescens in the Calcutta Herbaiyum proves that that plant is 

 not a Semecarpus, but a HoUgarna ; for it has quite the fruits and 

 spurred petioles of the latter genus. Its name ought therefore to be 

 changed to RoUgarna Kurzii ; the specific name albescens being too like 

 albicans which has already been applied to another s{)ecies. Kurz was 

 rather unfortunate in his treatment of this family. His HoUgarna 

 Grahami was not, as he supposed, the Semecarpus Grahami of W. and 

 A. which is a plant confined to the West of British India and which 

 does not extend to Burma. For the Burmese specimens included by 

 Kurz under H. Grahami, Sir Joseph Hooker has substituted the name 

 H. albicans, (Fl. Br. Ind. II, 38.) My own opinion, however, is that 

 these Burmese plants are notliing more or less than H longifolia of 

 Roxburgh, of which species that author has left an admirable coloured 

 figure in the Calcutta Herbarium. 



Besides the foregoing there are, in the Calcutta Herbarium, speci- 

 mens fiom Perak (King's Collector, No. 6623) of a species of Seme- 

 carpus which, except in the finer reticulation of the leaves, agree excel- 

 lently with Beccari's Bornean specimens. No. 2875, and 3818, which have 

 been named S. glauca by Dr. Engler. (DC. Mon. Phan. IV, 478).
