992 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. [(. pseudo-rivalis 
Fruit broadly ovoid, very distinctly and suddenly contracted into about a 3 mm. 
long beak, 17 mm. in length, including the beak. and the perianth and 11 
mm, broad; scales light-yellowish, distinctly channelled along the middle, with 
very narrow scarious  erosely toothed margin and fuscescent tip. Seed ovate, 
somewhat compressed, 9 mm. long, 7 mm. broad, 5 mm. thick, with the 
surface almost polished and of a brown-yellowish colour when freed from the 
dry friable dark integument, deeply alveolated on the back and with a rather 
deep oval chalazal fovea in the centre of the raphal side, from which radiate 
several furrows; albumen equable; embryo basal. 
HaBrrAT.—Southern India in the Canara district, collected by the Rev. 
Metz. 
OssERvaTIONS.—I have seen a very incomplete authentic specimen of this 
Calamus in the Berlin Herbarium labelled: **Hohenacker—Pl. Indiz Orient. (Terra 
Canara); in montibus Ghats pr. Honore” (sic). The specimen is the upper portion 
of a leaf not fully expanded and a portion of a spadix with a few quite ripe 
fruits. 
C. Metzianus seems to me only a continental form of C. rivalis, from which 
it differs in the larger fruit with the scales distinctly channelled along the 
middle. sie 
.. In the Munich Herbarium I have seen the specimen referred by Martius to C, 
rudentum Lour. which I consider as belonging to C. Meízianus ; it is labelled 
' East India, Heyne" and probably comes from the same region as the type- 
specimen, the said botanist having made his collections chiefly in the southern 
districts of the Indian Peninsula. Heynes specimen has a partial inflorescence 
40 cm. long and bears 12-13 spikelets on each side; the secondary spathes are 
unarmed. 
Should C. Mezzianus prove identical with C. rivalis, the first name has the 
precedence, having been published many years before the second.
