Richards., in Frankl. Narrative, p. 738; 5. longipes, Goldie, Hooker, 
according to specimens from Beechey Island, in Arctic Ainerica, com-

only is found in Spitzbergen. It is very general on mountain-sides 
and on islets up to Brandywine Bay and Low Island. In flower at 
Brandywine Bay, 27th July. It is very variable in appearance and in

a. foliis oblongis vel elliptico-lanceolatis, caule 6—8-pollicari. 
B. latifolium, Hrtm. Herb. N. Fasc. ix. n. 29 
. cespitosum, nob., which I should consider a good species, but for 
the transition forms. . C. vulgatum, Smfit., belongs to this variety. It 
may be thus characterized :— C. cespitosum?; caulibus 1—3-floris, 
inferne glaberrimis, superne pubescentibus ; foliis infimis persistenti- 
bus, ovato-ovalibus, obtusis, sepe quadrifariam imbricatis (ut in 
Sazifr. oppositifolia), glaberrimis vel basi ciliatis, foliis summis late 
ovatis, glabris, eiliatis, bracteis ovatis carinatis, versus apicem margine 
membranaceis, dense ciliatis, carinaque parce hirsutis; sepalis ovatis, 
obtusis, apice late membranaceis, petalis calyce 2—3-plo longioribus, 
apice bifidis; capsula ? 
C. cespitosum forms close perennial tufts, 2—3 in. broad and 1-} in.
