OxsERvATIONS.— This Calamus offers a very curious case of variability in a species, 
for in the vegetative organs it is almost identical in every detail with the “ forma 
typica" ‘of C. paspalanthus from Sarawak, while it differs considerably from the 
type in the very peculiar shape of the seed, 
SUPPL. PLATE 26,—Calamus paspalanthus var. pterospermus Becc.—The upper end 
of a plant, with an entire very young female spadix; the summit of a leaf; a 
partial inflorescence with mature fruits; detached seeds, one cut longitudinally 
through the embryo, The type specimen Winkler No. 2882.

Expedition collected by Dr. Thorel (Herb. Paris). I have reduced @C. multiramea (sic.) 
Ridley to C. Guruba after inspection of the type specimens (No. 8405, from Dinding 
in Perak) kindly forwarded to me by Mr. Ridley himself; they consist of 
a portion of the sheathed stem, an entire leaf, and spadices with male 
flowers; all these parts agree exactly with the corresponding ones of €. Guruba 
from Assam; but with these is mixed a portion of a spadix with fruits nearly 
ripe, which mest certainly is referable to C. concinnus Mart., a species first dis- 
covered by Helfer in the Mergui Archipelago, and not found again until 
now by modern collectors. lt is this fruiting spadix which Ridley describes as 
“that of €, multiramea.

Description.-l can now complete the description of this species, which wa 
known only through a few detached fruits, having been able to study a specimen, 
lent to me by Mr. Burkill and consisting of a portion of a leaf and of an entire 
partial inflorescence in fruit; this specimen was collected in S. Coimbatore, Madras 
(Herb. Rep. on Economic Products to the Government of India No. 23503).
