attention to Arundinaria niitakayamensis, suggesting that the Philippine plant 
is identical with the Formosan one. On making application to Doctor Hayata, 
he most kindly sent me a specimen of his species with both leaves and flowers, 
an examination of which proved Mr. Merrill’s suggestion to be correct. There are 
slight differences in the flowers, it is true, such as the smaller, not so long-awned, 
outer empty glumes, but in other respects the specimens agree, and Doctor Hayata 
also, writing to Mr. Merrill, expressed himself of the same opinion. 
The culms appear most generally to reach a height of 1 m or less, sometimes 
in more sheltered places 2.5 m, the diameter near the base 1 em or less. The 
internodes are about 10 cm long and the culm-sheaths are rather longer, striate 
and hispid on the back, acuminate at the tip, and with a short-acuminate 
pseudophyll. The branches have quite short internodes, persistent chaffy sheaths, 
and small, much crowded leaves; as in the Formosan plant, the cross-bars ‘of the 
leaf-nerves are about 5 per millimeter. The flower-panicles are terminal, and 
few-flowered, the spikelets are about 2 cm in length (shorter than in the For- 
mosan plant where they reach 3 cm in the material available), and there are 
usually about six flowers to each spikelet. The caryopsis is unknown. 
As originally suggested by Mr. Merrill, following Doctor Hackel, this species 
resembles the Japanese Arundinaria pygmaea Kurz (Bambusa pygmaea Miq.), 
but differs in its narrower leaves; it also comes near to A. densifolia Munro, of 
the mountains of southern India and Ceylon, but that species has spikelets with 
only one flower.
