NOTE ON PHILONOTIS LAXA Liver. 
By H. N. Drxon, M.A., F.L.8.

“Flowers and fruit unknown. Perhaps an aquatic form of 
marchica. Tufts very loose, flaccid, light green. Stem much 
floating, thin, weak, with few smooth radicles, 
simple or divided, never with whorled branches ; bearing deciduous 
axillary shoots in the upper part of the stem. Leaves very loosely 
set, spreading both wet and dry, not decurrent, lanceolate, sharply 
pointed, not plicate, plane at margin and with short single teeth. 
Nerve very thin, only 85 » wide, ending in or below the point. All 
four or five times as long, below 18 p wide and two to four times 
as long, here and there in upper part of lamina slightly papillose 
with the projecting cell-walls.” 
hilonotis which occur with us. Indeed it 
resembles loose forms of Amblystegium Koc 
of the fontana group, and perhaps in saying 
idea of its very great distinctness. os 
spite of these marked characters, however, I felt very suspict®.!t 
as to the specific rank of P. lava, a suspicion shared by Limpricht
