W. H. PEARSON: HEPATIC. 21 
PLAGIOCHILA COMPTONII Pearson, sp. nov. 
Dioica, elata, fusco-viridis laxe eæspitosa. Caules ramosi ramis divergen- 
tibus. Folia subopposita patentia (50°) vel erecto-patentia (30°) oblongo- 
ovata vel oblongo-triangularia, margine antico (inferiore) decurrente 
integro vel dentibus paucis distantibus armato, margine postico (superiore) 
eurvato paulum ampliato ad caulis medium attingente, interdum ad basin 
reflexo, dentes magnos 7-15 gerente; apice truncato 2-3-dentato ; cellule 
parvulæ vel mediocres, subrotundatæ, pachydermes, trigonis nullis. Bracteæ 
late ovatee margine inferiore denticulato, superiore dentes magnos c. 15 
gerente, Perianthium braeteis immersum parvum oblongo-quadratum com- 
planatum, ore lato dentibus æquimagnis 35-40 ornato. Andreecia haud 
visa. 
Dimensions. Stems 2 to 3 inches long; leaves 2:5 mm. x 1:5 mm.; cells 
03 mm. ; bracts 25 mm. x 1°5 mm.; perianth 2°25 mm. x 1'5 mm. 
Obs. I have compared this species with a great number from Asia-Oceania- 
tropica, but find none like it, the nearest being P. Belangeriana Lindenb., 
from which it differs in cell structure and in the small hidden perianth. 
It has been referred by one authority to P. nutans St. ; but I have had the 
opportunity of comparing it with the original, from which it is quite 
different.

PLAGIOCHILA LACINIATA Pearson, sp. nov. 
Dioica, elatiuseula fusco-brunnea esspitosa. Caulis parum ramosus, ramis 
ascendentibus. Folia subopposita vel alterna contigua patenti-divergentia 
(70°) oblonga, margine antico (inferiore) recto vel parum curvato integro 
deeurrente, margine postico (superiore) curvato ad caulis medium attingente, 
apicem versus paucidentato; apice truncato 2-4-dentato ; cellule mediocres 
subrotundatæ pachydermes, trigonis nullis. Bracteæ oblongo-ovatæ mar- 
ginibus ambobus laciniatis, laciniis longis ligulatis simplicibus bifidisve 
perianthium circumyestientibus. Peranthium late breviterque obconicum 
ore laciniis longis fimbriato. 
Dimensions. Stems 14 to 2 inches long, diam. *2 mm.; with leaves 4 mm. 
wide; leaves 2 mm.x 1 mm., 2:5 mm.x 1 mm., 3 mm. x 1'25 mm.; cells 
+035 mm.; bracts 2:75 mm. x 1:5 mm.; perianth 1:5 mm. x 1'5 mm., laciniæ 
1 mm. to 1°5 mm. long; processes 3 mm. x ‘3 mm., 1:5 mm.x ‘2 mm. 
Obs. Specimens of P. fructicosa Mitt. Bootang, Himalaya, coll. Rev. L. 
Dural, det. Schiffner (ex Herb. Levier) come nearest to it, but have a 
narrower leaf with fewer and coarser teeth, perianth with shorter and few 
laciniz. 
Why this species should be placed in section Brevifolia by Stephani 
I cannot understand.
