Below the summit of Ben Lawers, W. West, August 1880. Ben
Laoigh, Peter Eioing, September 1882. Glen Callater, Prof.
Balfour, 1841.
Found on the Continent.
Obs.—Distinguished from A. julacea (L.) by its smaller size,
paroicous inflorescence, the antheridia being found at the base
of the bracts immediately below the perianth, the somewhat
secund leaves, which are much laxer in texture, and the perianth
being less cylindrical, with the folds not so deep at the lower
portion.
I detected this species first as British from specimens oolleoted
by Mr. West on Ben Lawers in 1880, who had named it Antlielia
julacea. In Dr. Carrington’s herbarium, specimens collected in
Glen Callater by Prof. Balfour in 1841 and named Anthelia julacea
var. clavuligera Nees, belong to this species.
Prof Lindberg refers the Jung, nivalis of Swartz (J. nivalis
Sw., W. M. Ind. muse., p. 5. (1803); Whalenb. PI. Sueo., pro
parte) to this species, but on this matter Dr. Spruce writes ;
“ However that may be, there is no evidence to show that either
Swartz or Wahlenberg discriminated between the two forms, and
did not equally include the J. julacea of Lightfoot, as well as
J. Juratzkana, under their name, J. nivalis-, so that to Limpricht
belongs the honour of first distinguishing J. Juratzkana hy its
inflorescence.”
