20. Cerastium (Strephodon, Recticapsulares) oxalidiflorum Makino, 1. c., 
p. 102. 
Perennial, caespitose; the flowering stem attaining about 36 cm in 
height, the numerous sterile stems much shorter than the flowering stem. 
Rhizome ramose, creeping, rooting. Stems slender, ascending, often 
geniculate below, terete, foliate throughout, pubescent with ascending 
hairs but glanduloso-pubescent above, turged at nodes, viridescent; inter- 
nodes attaining about 9 cm or sometimes 13 cm in length. Leaves oppo- 
site, erect-patent or spreading, lanceolate, but subspathulate in the inferior 
ones, acuminate or acute, gradually attenuated towards the sessile or 
Subpetiolated bases, entire and ciliated, thinly pubescent with adpressed 
hairs on both surfaces, subflaccidly herbaceo-membranaceous, green 
above, paler beneath, attaining about 8 cm long, 18 mm wide, shorter 
or longer than internodes; midrib prominent beneath; veins inconspicuous 
superficially, loose, ascendingly erect-patent. Dichasium subnumerous- 
flowered, twice to thrice divided, extending about 4—9 cm in flower, 
glanduloso-pubescent with patent hairs; branches erect-patent, the first 
lateral branches attaining about 31/, cm in length in flower but attaining 
àbout 7 cm, sometimes 11 em, in fruit; bracts small, subulate, acuminate 
or acute, but minute and ovato-oblong with an obtuse apex in the 
Superior ones, glanduloso-ciliated, herbaceous, green; the first pair larger 
than the rest and 4—8 mm long but occasionally foliaceous. Flower 
pedicellate, large, 15—19 mm across, white; pedicel 9—25 mm long in 
flower but attaining about 5 cm long in fruit. Calyx erect, campanulate. 
Minutely glanduloso-pubescent with patent hairs externally, light green; 
sepals 5, ovato-lanceolate and glanduloso-ciliated-margined, but oblong- 
elliptical and hyalino-margined in the inner ones, obtuse, herbaceo-mem- 
branaceous, 5t/,—6 mm long, 2—3 mm broad, 3-nerved, the outer 
Darves ramose from the base. Petals 5, about 2!/,- nearly 3-times as 
long as the sepals, patulose above, subspathulato-oblong, angustato- 
Cuneately attenuated below and loosely ciliated on margin towards the base, 
entire, rounded or subretuso-rounded at the apex, 14—16 mm long, 
4—5 mm Wide, 7-nerved, thinly membranaceous between nerves; nerves 
Parallel and elevated on the inner surface, fasciculately ramose into fine 
Veinlets above. Stamens 10, shorter than petals and about ?/,—?/, as 
long as them, about 10 mm long, the oppositisepalous ones slightly 
longer; filaments very shortly connate at the base, compressed, white, 
the Oppositisepalous ones subulato-filiform glabrous and thick at the
