Fimbristylis lineatisquama
Content
Description
Perennial with short rhizome.
Leaves half as long as the stems, rather stiff, curved, flat, rather abruptly acuminate, densely hairy in the lower part, scabrid on the margins, 1½-2 mm wide;
Inflorescence simple or compound, loose, with 4-10 spikelets, 2-5 cm long.
Stamens 3;
Distribution
Asia-Tropical: Philippines (Philippines present), Benguet Subprov present, Golo present, Luzon present, Pauai present, Sulu Is present
Malesia: Philippines (Sulu Is.: Golo). With certainty only known from the type-collection (MERRILL 11546); a poor collection from Luzon (Benguet Subprov., Pauai: CLEMENS 9145) may belong here.
Notes
The description of F. urakasiana , based on a collection from the Mariannas, Urakas Island (GIBBON 1158, not seen), agrees very well with that of F. lineatisquama, so that I presume that the former name is the correct one for this species.
According to , F. urakasiana is conspecific with F. boninensis [F. longispica STEUD. var. boninensis — F. dichotoma subsp. longispica KOYAMA var. boninensis KOYAMA, l.c.], but this is very unlikely, as F. boninensis is a plant with contracted, head-like inflorescence, glabrous leaves, and broad, obtriangular- obovate nuts. F. boninensis is recorded for the Philippines: Batan Island, on the littoral cliff on the eastern foot of Mt Iraya, frequent: HATUSIMA 28713 (not seen). See .
In shape and texture of the nuts and in the setulose top of the connective F. lineatisquama shows much T affinity to F. trichophylla. It can be distinguished by the long-ciliate ligule and the longer, more dis- tinctly nerved glumes. The delimitation against F.trichophylla and F. tomentosa requires further investigation.
