VALLfSN ERIA Micheli
Vallisneria spiralis Blanco FI. Filip. (1837) 781; ed. 2 (1845) 538; ed.
(1879) 187, non ? Linn.=VALLISNERIA GIGANTEA Graebn. in
Engl. Bot. Jahrb. 49 (1912) 68.
Although the Philippine form has recently been described by
Graebner as a distinct species, Vallisneria gigantea, I am by
no means convinced that it is specifically distinct from V. spiralis
Linn. It is found in shaHdW’ ¿oridi an^Tsf^w streams through?
out the Philippines at low altitudes and is exceedingly variable,
"its size depending largely, if not entirely, on the depth of the
water in which it grows. The native name cited by Blanco,
cintascintasan is from the Spanish cm£as=ribbon, and merely
means ribbon-like.
Illustrative specimen from Calumpit, Bulacan Province, Luzon,
January, 1915 (Merrill: Species Blancoanae No. 667).
