I supposed (see pp. 181, 364, 501 of this volume) that C. Jjavensis could be 
identified with C. penicillatus Roxb. (printed pencillatus) if, in Roxburgh’s description, 
the phrase “thirty-four pairs of leaflets” could be read ‘‘3-4 pairs.” Accordingly 
Colonel Prain kindly looked up for me in Roxburgh’s manuscript of the ‘ Flora 
Indica” which is at Kew, and found that in the original diagnosis of Calamus 
penicillatus he did actually write “3-4,” not “34 pairs.” 
Ridley also believes (Materials, ii. 192) that C, penicillatus Roxb. (which he 
ostentatiously writes pencillatus) is ‘“‘undoubtedly” the common ©. javensis Bl. 
As a matter of fact, however, Roxburgh’s Calamus is a plant quite different from 
€, javensis of Blume, as I have been able to verify from Rexburgh’s type-specimen 
of C, penicillatus in the Herbarium of the British’ Museum; I have also satisfied 
myself that this specimen exactly corresponds to Gaudichaud’s plant, which Martius 
had rightly identified with Roxburgh’s C. penicillatus, and which received from me 
the name of C. Martianus, and under this name is represented in plate 157 of this 
volume; we may even suppose that both  Roxburgh's and Gaudichaud's specimen 
have the same origin, and are from the same gathering. In conclusion, the name 
of C. penicillatus can in nowise be substituted for the old and familiar one of 
C. javensis Bl. for they are two widely different species; it is also quite certain that 
C, Martianus Becc. is.a synonym of C. penicillatus Roxb.

CALAMUS JAVENsIS var. 'TETRASTICHUS Bl. Add:—Bece. in Engl. Bot. Jahrb. 
v. 48 (1912), 91. . : és 
Specimens of this variety exactly corresponding to Plate 38 of this volume, have 
been collected by H. Hallier in N. W. Dutch Borneo at Amai Ambit in the Residency 
of Sambas (No. 3309 in Buitenzorg Herbarium). Some of the female flowers are 
transformed into narrow elongate galls. Also in S. E, Borneo, at Ndessa ( Winkler 
No. 3142). 
CALAMUS JAVENsIS Bl, var. TETRASTICHUS subvar. MOLLISPINUS Bece, 
Leaves and spadices as in variety tetrastichus, but the Jeaf-sheaths covered with 
innumerable brown, concolorous, very slender, needle-like flaccid Spines, 6-10 mm. 
long or at times much shorter; the female spadiz has rather short partial inflor- 
escences which carry 6-7 spikelets kept spreading by a conspicuous axillary callus ; 
the primary spathes have an elongate ear-like limb, which is produced 5-6 cm. 
beyond the’ insertion of the partial infloresences; the secondary spathes are also
