leaves, broadly ovate to cordate-ovate, bidentate, sinus from 

 1-10 to 1-5 deep, acute, margin as in leaves ; inner bracts 

 3-lobate, irregularly dentate. On the margins of these inner 

 bracts were numerous cellulce clavulce, which Leitgeb states 

 to be peculiar to Gesia as distinct from Marsupella. Pistil- 

 lidia 10, long, capsule not seen. Androecia terminal on 

 lateral branches, 4 to 6 pairs of leaves, ovate-quadrate, 

 emarginate sinus and segments obtuse, antheridia 2 in each 

 leaf, oval, stipitate.

 •175 mm X "125 mm. 



Obs. — In habit resembling Gesia corallioides. Differs from 

 it in its monoicous inflorescence, margin of leaves being 

 irregularly crenulate, with long narrow cells, although in 

 Gesia corallioides the margins of the leaves are so diaphanous 

 and scariose that the cell structure can scarcely be defined, 

 yet the cells always retain their quadrate shape. 



Qesia crenulata, which it resembles in size, is also dioicous, 

 margin of leaves more regularly and deeply cx-enulate, with the 

 marginal cells shorter and more conical, leaves always 

 bidentate.
