40 PLANTS FROM NEW CALEDONIA. 
125 mm. ; cells ‘015 mm., keel cells ‘02 mm.; underleaves ‘05 mm. x ‘05 mm.; 
bracts, lobe ‘2 mm. x:125 mm., lobule ‘125 mm, x ‘05 mm.; bracteole 
'2 mm. x ‘125 mm., segments ‘075 mm. 
Obs. The constant reddish-brown colour distinguishes it at onee from all 
other Microlejeunew I have scen. 
Differs from M. albicans (Nees) in its colour and other characters given 
by Stephani, but agrees with the description of this species given by Evans 
in his Hawaiian Hepatice (Trans. Conn. Sc. vol. x. p. 445, 1900), except in 
the colour.

On upper surface of fallen log. Forest, 3000 ft. 740. Ignambi. On 
rocks, by creek, 3000 ft. 1530. 
LEPTOCOLEA COMPTONIT Pearson, sp. nov. (PI. 8. figs. 35-46.) . 
Monoica, parva pallidissime viridis vel alba, supra muscos et hepaticas 
repens. Caulis cellulas 3 angustas latus pinnatus, ramis brevibus. Folia 
imbricata ; lobus patenti-divergens (70°) ovalis semi-oblongus vel obovatus, 
margine antico (superiore) arcuato caulem obtegente, postico (inferiore) 
recto vel curvato, apice rotundato; lobulus quam lobus 4-plo minor ovalis 
vel ellipticus, 2-plo latior quam altus, tumidus, margine superiore involuto, 
angulo libero obtuso, carina arcuatä levi. Textura tenerrima ; cellule 
mediocres quadratæ vel oblonge 4—5-6-gonsz leptodermes, trigonis minu- 
tissimis. Foliorum margo integer e cellulis angustis hyalinis, que per 
instrumentum microscopicum oculis percipi vix possunt, compositus. 
Flores femineæ crebræ, in ramis brevibus terminalibus positæ, vel innova- 
tione singulà florigerä suffultæ ; bractearum lobus ellipticus integer, ad 
instar foliorum hyalino-marginatus, apice obtuso ; lobulus fere ! minor late 
lanceolatus, apice obtuso. Perianthium late pyriforme compressum, apice 
obcordato, antice planum, postice obtuse carinatum, marginibus integris. 
Andrecia in ramis brevibus sita; bracteæ in paria 4 dispositæ ; lobus 
ovalis, apice rotundato; lobulus similis sed minor. 
Dimensions. Stems 4 inch long, diam. ‘06 mm. ; with leaves 1:25 mm. 
wide ; leaves, lobe 1 mm. x 7” mm., :9 mm.x:6 mm., ‘7 mm. x'55 mm. 
‘7 mm.x:45 mm., lobule *3 mm.x:175 mm., :3 mm.x:15 mm.; cells 
03 mm. x ‘05 mm., ‘03 mm. x ‘04 mm., hyaline fringe cells ‘03 mm. long, 
x Ol mm. wide ; bract, lobe *65 mm. x:3 mm., lobule *4 mm. x:175 mm. ; 
perigonial bract, lobe *3 mm. x:2 mm., lobule :2 mm.x 15 mm. 
Obs. There is no Leptocolea listed by Stephani from Asia-Oceania near 
this; the beautiful hyaline fringe of narrow cells on the leaves is a striking 
character. | 
Leptocolea caledonica (Gottsche) has falcato-elliptie leaves (1:33 mm. x 
‘3 mm.), lobule bidentate, bracts lanceolate or narrowly lingulate (1 mm. x 
'9 mm.), and no mention is made of any hyaline fringe of the leaves by 
Gottsche or Stephani.
