Add to the localities;— S. Coimbatore (Herb. Rep. Econ. Prod. of India 
No, 25862), Specimen forwarded to me by Mr. Burkill. 
104. CALAMUS MELANACANTHUS Mart. 
I have received from Mr. Burkill a specimen of this Calamus, which was 
known only from Wallich’s No. 8606 B, Burkill’s specimen bears portions of a 
fruiting spadix corresponding exactly to the type of Wallich; it bears the label :~ 
‘‘Thaungyan, Tenasserim, Burma. Vern, name “Medan” (Herb. Rep. Econ. Prod. 
of India, No. 21002 |a)."

105, Caramus Dreressorsti Mig. var. ExuLANS Becc. in Philip. Journ, Se, 
Botany, v, (1902) 627, and vi, (1911), 250, 
DescripTion.—This possesses a great likeness to some Malayan forms in the 
spinescence of the leaf sheaths, in the extraordinary length of the spadices and in 
all its principal characteristics; it differs only in the leaflets, which are without 
bristles on the mid-costa above, but beneath have the  mid-costa closely bristly 
and the side nerves smooth, In the Malayan forms the leaflets have long bristles on 
three nerves beneath, the mid-costa being smooth, while the mid-costa above is 
bristly. The femule spikelets of this variety are also less distinctly zig-zag sinuous, 
the involucre of the flower does not form so regular and deep a cup as in the 
type, and the areola of the neuter flower is crescent-shaped and not roundish, 
Otherwise the similarity of the Philippine variety to the Malayan type is quite 
evident. 
Hasirat.—Philippines. The male plant was collected by P. W. Foxworthy in 
March 1906 on Mount Victoria, in Palawan, (Herbarium Bureau of Science) Manila, 
No. 756; and the female by  Loher in Luzon at Montalban, Province of Rizal, 
Mareh 1906, (No. 7054 in Herb. Kew. Vernacular name **Palimanac)" and in the 
Island of Polillo on Mount Malulud by Robinson (Herb. Bur. Science Manila No. 9111.) 
OssERVATIONS —The male specimen has a leaf 15 m. long; the leaflets are 
numerous, equidistant, subtricostulate; the mid-costa is rather prominent above, 
bristly spinulous near the apex, and the side costae have long bristles; underneath 
the mid-costa is furnished with bristles, and the side nerves are smooth. The male 
spadix is as usual extraordinarily long, and not essentially different from that of 
the Malayan type plant but the seeondary and tertiary branches and the spikelets 
are inserted just at the mouth of their respective spathes which terminate in 
a broad, horizontal, or deflexed point; the male flowers also are slightly smaller, 
more approximate, inserted at a wider angle, and therefore have the spathels 
shorter and less distinctly infundibuliform.
