One of the largest genera of Hepatic/s, found in all parts of the world. Of the following 
sections, § 1 is well marked, but the others are often difficult of recognition. The species 
are very puzzling to identify. 
§ 1 . Leaves opposite , vertical, connate at the base.

erect, proliferouslv divided, stoloniferous. Leaves obliquely orbicular-reniform, 
denticulate and ciliate. Perianth terminal, obconic ; mouth truncate, denti- 
culate and ciliate. — Hook. Muse. Exot. t. 91 ; Syn. Hep. 52. 
Middle Island : Dusky Bay, Menzies. 
2. P. connexa, Hook.f. and Tayl. Ft. N. Z. ii. 130. Stems sparingly- 
branched, olive-brown or yellow, 1 in. high; apices incurved. Leaves orbi- 
cular, lower entire, upper subdenticulate. — Syn. Hep. 648.

in Herb. Hook. 
3. P. prolifera. Mitten in FI. N. Z. ii. 131. t. 94./. 5. Stems 2-3 in.
