HEPATICÆ MADAGASCARIENSES.

meant for Jung. hirtella Web., the third and smaller lobe having 

 been overlooked owing to its position; but still another difficulty 

 arises, for in all the specimens I have seen, the stem is quite 

 smooth, yet Hooker figures it as remarkably squamose. Where 

 the leaves and underleaves are crowded, the stem appears to 

 be squamose, but all the scales are on the basal wings of the 

 leaves and underleaves. 



Specimens trom Java (Teysman), Assam (Hb. Taylor), Pacific 

 Isles (Ditto), Bellender Ker Range, Queensland (F. M. Bailey), 

 all agree in having smooth stems and tripartite leaves. Stem 

 smooth, rootlets long, hyaline, fasciculate. Leaves tripartite, 

 antical lobe largest, entire or ciliate-dentate, with a long decur- 

 rent wing from which arise one or two long cilia, middle lobe 

 smaller and more ciliate, third postical, smaller still and very 

 ciiiate, all the lobes acutely reflexed. Underleaves bipartite, 

 ciliate dentate. 



5. Mastigophora diclados (Brid.). 



Hab. In silva Alamazautra, Julio, 1882 (196 K.). In mon- 

 tibus Ankaratra, 1879. (195 a K.) (196 b K.) (145 b K.) 



6. Isotachis serrulata (Sw.). 



Hab. In silva Alamazautra, Julio, 1882. (144 K.) 

 Obs. I see no character of any importance to separate this 

 from the type. 



7. Herberta adunca (Dicks.). 



Hab In montibus Ankaratra, 1879. (146 a K.) (194 K.) 



8. Herberta adunca (Dicks.) var. 



Hab. In montibus Ankaratra 1879, (195 K.). 



Obs. A variety with slender segments; this species is a 

 very variable one, as those who are acquainted with its growing, 

 well know. 



9. Microlepidozia — ? 



Hab. In montibus Ankaratra, 1877, (182 a K.).
