I.—By Wim Wess, F.L.S. 
ee ensue gathered in flower by Mr. H. Andrews at Grassing- 
rt Skipton, nineteen years ago, was shown to me, and, 
fruiting “ghaeaatek being absent, was considered as possibly P. 
calearea. Last year ie John Cryer, of Bradford, whose note on 
the locality follows, naa a series of specimens, some of which 
were submitted to Prof. Chodat, of Geneva, the monographer of 
the genus, ore ‘Vdentified the plant as P. amarella Crantz. Mr. 
Cryer has asked me to draw up the description of the plant, which 
follow 
Ws :— 
Rhizome (of well-developed plants) branching, each branch 
scale several flowering stem s from 25 to mm. high, barren 
a very short blunt apiculus, nae usually from 5 to 30 mm.,

tances apart of about one-fourth to one-half their length, wpper- 
most ones always overlapping the lower part of the raceme, ob- 
” lanceolate and giv length from 12 to 18 mm., often ae 
; tage from 2°5 to ae racemes terminal, from 12 to 65 m
