C. brevicuspis, huic peraffinis, ob nucem longe rostratam præ-

Carex rigidula, Franchet, MS. 
SHINGKING: Moukden to Yalos R. (Webster, 181!). Herb. 
Kew. 
Frequent in Japan. 
Franchet says the affinity of this species is with C. vulgaris : 
this can only refer to the examples with bifid style that Franchet 
included here.

Carex wahuensis, Boott, Carex, t. 351, quoad utriculum dextrorsum 
nucem superiorem (neque aliter). 
Boss Lars (Beechey, n. 70; C. Wright, n. 370). 
Beechey's plant has (as Hook. et Arn. describe) an oblong- 
lanceolate utricle, which is } inch long, stramineous, with 20-24 
nerves. Boott’s tab. 351 (except the utricle and nut above cited) 
is taken from the Sandwich plant which Boott subsequently 
published as a distinct species, viz. C. nuptialis, Boott (Carex, 
p. 175, t. 591). The nut has no beak, which character shuts it 
off from C. tenebrosa, Boott. 
Var. f. bracteosa, C. B. Clarke. Bractee longissimze, 2 inferi- 
ores usque ad 8-12 unc. longs, inflorescentiam longe superantes. 
Spica mascula subsessilis. Glume feminex longe aristate, in- 
feriores subbracteiformes. Bractea ima longius vaginata.
