W. H. PEARSON: HEPATIC. 15 
long, straight, or hamate cilium, with the margin of the lobes fringed with 
short spines ; cupules very large and high, exterior surface papillose. I have 
not had the opportunity of comparing it with specimens of M. Berteroana.

MARCHANTIA LEkcORDIANA St, Sp. Hep. in Bull. Herb. Boissier, vii. 
(1899) 525. 
Medium size; pale yellowish green in colour, Fronds simple, lobate, 
furcate or bifurcate, regular, narrow, plano-convexulous ; antical side flat, 
postical slightly convex, at the middle 20 small cells thick, with a few 
larger ones interspersed. Stomata numerous, regularly or irregularly dis- 
persed, clear, with no projecting interior cells, 3 tiers high of 4 barrel-shaped 
cells. Cupules small, mouth wide, spreading, not lobate, very shallow, 
margin dentate-spinulose, teeth 1 to 3 cells long, 2 cells wide at the base, 
exterior of walls verruculose, Scales oval, entire, or with a few very minute 
distant teeth ; appendages small, purple, reflexed, constricted at the base, 
reniform, orbicular or ovate, apex acute, margin dentate, with 10 to 12 teeth. 
Rays of male flowers 7, cuneate, apex retuse. 
Dimensions. Fronds 1 to 14 inch long, 5 mm. to 7°5 mm. wide; scales 
1 mm.x 5 mm.; appendages “4 mm. x:3 mm., 3 mm. X :25 mm. 
Obs As noted by Prof. Evans, the appendages to the scales afford an 
excellent character for discriminating the species of Marchantia. 
In M. Lecordiana they are very characteristic. I have had the opportunity 
- of comparing my specimens with the original specimens in the herbarium of 
the late Général Paris.
