margins cross the stem transversely without the least 

 tendency to decurrence. The apices of the leaves being 

 a little incurved, and the leaves themselves sub-conni- 

 vent, give the plants a canaliculate appearance.

2. C. BiLLARDiERi, Nees. Fl. N.Z., ii., 139. Stems 



3-5 in. long; prostrate, dichotomously branched. Leaves 

 green or brown, opposite, ovate, subacute, obscurely 

 2-dentate ; ventral margin arched ; dorsal straight, 

 6-9-toothed at the base, free or connate with that of 

 opposite leaf. Stipules imbricate, transverse, convex, 

 2-toothed, connate with the leaves below. Perianth 

 campanulate; mouth laciniate, fimbriate. Hook. Muse. 

 Exot., t. 61. Syn. Hep., 175. (PL viii.) 



Tasmania — Labillardiere, Menzies. (Australia, New 

 Zealand, Campbell's Island.) 



3. C. GuNNiANUS, Mitten. Stems creeping, vaguely 



branched. Leaves imbricate, sub-deltoid, bispinous at 

 the apices, dorsal margin spinous dentate, ventral 

 margin bi-dentate, suddenly arcuate to the stipule. 

 Stipule oblong, apex bi-dentate, extus 4-toothed. 



Stem 2 in. high, flaccid. Dirty pale brown. (PI. xiii.) 

 A remarkable species, possessing considerable resem- 

 blance to C. Billiardieri in the general outline and 

 dentation of its leaves, but its areolation is altogether 

 different. Fl. Tas., ii., p. 228. 

 Tasmania — Gunn. 



4. C. siNUOsus, Nees, Fl. N.Z., ii., 141. Stems 3-4 in. long, 



procumbent. Leaves crowded, brownish green, oppo- 

 site, ovate-oblong, obtuse, obscurely 2-toothed at the 

 apex, connate, or almost so, by their dorsal bases; 

 ventral margin undulate ; dorsal very decurrent ; involu- 

 cral incised. Stipules distant, spreading, 5-partite, 

 segments toothed, connate with the leaves below. 

 Perianth ovate ; mouth laciniate, inflexed. Svn. Hep., 

 175. Hook. Muse. Exot, t. 113. (PI. xiii.)' 



C. ohlongifolius, Hook. f. and Tayl. in Lond. Jour. 

 Bot., 1845, 563. This species bears some resemblance 

 to J. integrifoUa, L. and L. ; in this, however, the 

 termination of the leaf is altogether destitute of the 

 two remarkable teeth present in our species. Syn. 

 Hep., 705.
