(27) D. Sabut Becc. in Hook. fil. F.B.I. vi. 469; Ann. Bot. 
Card. Calc. l.c. 181, t. 77. D. oligophyllus Becc. in Hook. fil. F.B.I. 
vi. 470; Atm. Bot. Card. Calc., l.c. 182, t. 78. 
Stem with rings bearing bristles and deflexed spines as in D. 
verticillaris but leaflets lanceolate, i ft. long, i in. broad or more, 
in groups of four some distance apart. Only portions of stem 
and leaves known. 
The specimen described under D. oligophyllus seems to be from a younger 
shoot of i). Sabut than the specimen of D. Sabut. 
These were both collected by Scortechini in Perak, on the Gunong Tarn- 
bang Batak. He gives the name Rotan Sabut {which is really the name of 
D, hystrix) to the plant. 
(28) D. macrophyllus Becc. l.c. 470; A7in. Bot. Card. Calc, 
l.c. 185, pi. 80. 
This plant has the same stem and arrangement of leaflets as 
D. Sabut, but the leaflets are 18 in. long by 3-75 in. wide. 
This was also collected by Scortechini, but was only a leaf specimen ; the 
spathes and spadix are unknown.
