NEW HEPATICiE. 267 



or deeurved, pale tawney. Inferior leaves very small, scarce- 

 ly wider than the stem. Perigonia are terminal linear spikes, 

 their leaves are smaller than the cauline and their tops 

 recurved. Differs from P. conjugata, Lind., by the shorter 

 shoots, and by the more closely imbricated and nearly entire 

 leaves. 



20. P. Dicksoni, Hook. fil. et Tayl. ; caule elongato, laxe 

 csespitoso, vage ramoso, sub apice prolifero, ramis basi 

 denudatis, complanotis ; foliis approximatis, erecto-paten- 

 tibus, rotundato-obovatis, apice dentatis, margine dorsali 

 decurrentibus ; calyce demum axillari, compresso, ex an- 

 gusta basi obovato, ciliato. 



Hab. Dusky Bay, Mr. Menzies. From Mr. Dickson, 



1814. 



Stems weak, with their repeatedly proliferous shoots 6-7 

 inches long, appearing here and there to be interruptedly 

 leafy from the bases of the new shoots being nearly naked. 

 Shoots of a pale tawney colour, usually solitary. This is 

 allied to P. laxa, L. et L., which, however, has leaves more 

 distant and more elliptical, and the interrupted appearance 

 of the shoots arises from the occurrence of narrower peri- 

 gonia. 



21. P. intertexta, Hook. fil. et Tayl. ; caule laxe csespitoso, 

 procumbente, vage ramoso ; surculis compressis, subflex- 

 uosis j foliis laxe imbricatis, subhorizontalibus, patentibus, 

 dimidiato-ovatis, apice rotundatis, dentato-ciliatis, mar- 

 gine ventrali cristato, dorsali recurvo ; calyce obliquo, 

 campanulato, compresso, ore ciliato. 



Hab. Norfolk Island. Allan Cunningham. 



Patches several inches wide, dusky olive-brown. Stems 

 2 inches long. Leaves when dry with both margins recurved, 

 by which character the species may be known from P. subplana, 

 Lind. j besides, the leaves are more imbricated, and are den- 

 tato-ciliate nearly all round their margin ; the calyx too, 

 is angulato-truncate.
