2 Pearson, Hepatics from the Cameroons 



Dimensions. — Stems i cm. long ; trunk .3 mm. wide ; 

 branches .4 mm. wide ; .1 mm. thick at the middle, upper layer 

 of cells .04 mm., cells of mid-rib 1.0 mm. by .05 mm., cells of 

 wings .05 mm., bracts of calyptra .3 mm. by .15 mm. at middle, 

 calyptra 1.5 mm. by .25 mm., capsule .5 mm. by .15 mm., 

 amentula .1 mm. by .2 mm. 



Hab. — Collected on ebony imported into Liverpool Docks, 

 January 1920, from the Cameroons, West Coast of Africa, by 

 Mr. W. G. Travis, a keen Liverpool botanist, whose name I 

 have the pleasure of associating with the plant. 



Observations. — This is one of the smallest Aneurce known ; 

 as the <J and $ are perfectly developed, I have no doubt 

 as to its being its normal size. Aneura limbata, St., from the 

 Cameroons, which I have had the opportunity of examining, 

 is a plant twice its size, with much more distinct wings, 

 calyptra clavate, hairy. 



A curious feature about the plant is that the upper layer 

 is composed of smaller cells, with very delicate walls; in the 

 next layer, which is the most prominent, the cells are larger 

 with thicker walls ; the mid-rib is composed of elongated cells. 

 In Aneura [ limbata, St., the mid-rib has elongated cells, but 

 the cells of the wings are smaller, giving the plant a very 

 winged appearance.

Lophocolea Newtoni, St. 



Observations. — The admirable geographical classification 

 of Stephani's " Sp. Hep." enables a student to arrive at a 

 satisfactory determination of a species with some certainty ; 

 there are 4 species with long, bidentate leaves recorded from 

 the West Coast of Africa, and my specimens agree with the 

 description of L. Newtoni from the Cameroons, collected by 

 Zenker ; leaves oblong, triangular, apex twice as narrow as 

 base, bispinose, segments sub-equal, short, narrow, divergent, 

 no trigones, underleaves quadrifid to the middle, segments 

 narrowlv lanceolate.
