Notes
PALLA distinguished between Helothrix philippinensis and H. axillaris as follows:
H. philippinensis. — Spikelets 4-4½ mm long. Glumes purple or blackish purple, the fertile ones c.3 mm long. Style 1½-1¾ mm. Nut 1-1½ by ¾-4/5 mm.
H. axillaris. — Spikelets 2-2½ mm long. Glumes green or purplish variegated, the fertile ones 1½- 2 mm long. Style ½-¾ mm. Nut ¾-1 by c. ½ mm.
Although in general the Philippine plants have somewhat longer spikelets and slightly larger nuts than the Australian ones they cannot be separated specifically. The spikelets in Australian specimens are not rarely 3 mm long, sometimes up to 4 mm, in some Philippine specimens they are pale coloured. The New Guinea specimens have small nuts, but in other characters they are intermediate between the Australian plants and the Philippine ones. As in S. erythrosiphon OHWI the spikelets, nuts, anthers etc. completely agree with those of S. maschalinus, I take it for a slender form of the latter.
