 2-lobed, conduplicate, the upper lobes larger, concave, bifid, 

 serrated at the point, the lower oblongo-ovate, saccate. Weis. 

 PI. Cr.p. 123. Hook. Br. Jung. t. 68. 



On subalpine bogs ; common : fruit unknown.

On trees ; frequent. This species has lenticular gemmae. Pencils 

 of fibres, from the duplicature between the lobes of the leaves, expand 

 at their terminations into flat discs, by which the plant adheres to 

 subjacent substances, as occurs in the Virginian Creeper. The seeds 

 are large in proportion to the spiral filaments. 



B. Stipulate. 

 a. Leaves entire or rarely emarginate.

 nal; calyx ovate, compressed a little at the mouth, truncated, 

 2-lipped. Hook. Br. Jung. t. 56. J. anomala, Hook. Br. Jung, 

 t. 24.

49. J. polyanthps, Linn. Leaves plane, rotundato-quadrate, 

 entire or emarginate ; stipules oblong, bifid ; fruit on short pro-

50. J. cuneifolia, Hook. Stem creeping; leaves rather re- 

 mote cuneiform, entire or very obtusely notched at the ex- 

 tremity ; stipules minute, ovate, bifid. Hook. Br. Jung. t. 64.
