2576. Carex flava, L. Some members may like to have 
Kukenthal’s description of the three species, C. flava, L., C. lepido- 
carpa, Tausch, and C. Oederi, Retz : — 
A. Stem tall. Perigynia long beaked = C. flava and lepidocarpa. 
1. Leaves 3-5 mm. broad, yellowish green. Female spikelets 
ovate or sub-globose, not very compact. Perigynia 5-6 mm. 
long, all having a long beak which is gradually contracted 
and obliquely deflexed= C. flava. 
2. Leaves 2 mm. broad, intensely green. Female spikelets 
oblong-oval, compact. Perigynia 4 mm. long with a long 
detlexed beak which is abruptly contracted = C. lepidocarpa. 
B. Stem short. Perigynia 2-3 mm. long with very short, straight, 
abruptly contracted beak = C. Oederi. 
Forma oedocarpa (Anders.) differs in its pedunculate male 
spike, and in ihe female spikelets being more or less remote 
bracts erect, patent, and perigynia with a long beak.

in ‘ Ann. Scot. Nat. Hist.’ 236, 1910. “ Stems 2^ feet high, leaves 
broad and thick with strong nerves ; male spikes 2-3 stout sessile, 
rigid, and where there are 3, the lower one with female flowers for 
a third. Fern, spikes generally 4, upper 3 sessile (lower 2 in. long, 
upper I in.), 6 mm. thick, fruit densely compacted, not interrupted, 
k'ruit subrotund with a short entire beak, glumes unequal, greenish, 
with a brighter brown edge all round. Banks of Nith, Sanquhar,

[2568. C. SYLVATicA, Huds., var. capillariformis, Arnold 
Lees in ‘Naturalist,’ p. 349, 1910. A form growing in open 
ground associated with Equisetum palusire, Orchis maculaia, etc. 
I have sent it to Kiikenthal, who considers it to be ordinary Carex 
sylvatica. 
2682. Mibora minima, Desv. Usually described as 
flowering in spring, but a tuft brought home continued in flower at 
Oxford till August. Mr. F. J. Hanbury tells me it seeds plentifully 
in his Sussex garden.
