Sordide viridis, olivacea, et subnigra. Caulis polliearis, bipinnatus. Folia marginibus dorsalibus seepe decola- 

 ratis albidis patulo-recurvis, ventralibus medio sinuatis et cum auriculis compressis cauli adpressis. AmpMgastria 

 sinu parvo bifida. Perianthium Iseve, dorso convexo, apioe supremo tantum lsevissimo bicarinato. 



This species has a very close resemblance to F. squarrosa, so that without the perianths the plants might be 

 confounded. The form of the leaves and lobule is as in F. pycnantha, and their true form is only to be seen by 

 pressing them out, for the lower portion of the leaf with the lobule is curved round on the ventral side of the stem, 

 so that the lobule is forced round with it. — Plate CIII. Pig. 6 : — -1, stems, natural size ; 2, a portion of the same 

 with leaves and stipules ; 3, a perianth and involucral leaves as seen on the ventral side ; 4, a transverse section of 

 the perianth about the middle; 5, the same just below its apex : — all magnified. 



3. Frullania pycnantha, Hook. fil. et Tayl. ; caule procumbente ramis brevibus pinnatim ramoso, 

 foliis patenti-recurvis late ovatis apice rotundatis lobulo parvo galeseformi compresso, amphigastriis sub- 

 orbiculatis bifidis medio carinatis marginibus subrecurvis, perianthio oblongo obovato dorso convexo ventre 

 unicarinato toto superficie lacinulis minutis obsito, foliis involucralibus conformibus lobulo ovato-lanceolato 

 parce lacinulato dentato basi cum arnphigastrio oblongo profunde bifido laciniis divergentibus lanceolatis 

 extus repandis dentatisque coalitis. — Lond. Journ. Bot. 1844, jj. 566. G. L. et N. Syn. Hep. p. 411.

Olivaceus, rufesceus. Caulis 1-1^-pollicaris, gracilis. Folia imbricata, apice patenti-recurva, squarrosula, 

 margine ventrali sinuato lobuloque incurvo. Perianthium. obtusum, apiculatum. 



Very closely allied to F. ceololis, Nees, F. ericoides, Nees, F. squarrosa, Nees, F. squarrosula, and probably also 

 to F. laciniosa, Gottsehe, but apparently distinct in the form of its perianth. It is a much smaller plant than 

 F. squarrosa and F. squarrosula.

Hab. Northern Island : on the bark of trees, Titiokura, Manawatu Eiver, Colenso. 

 The specimens referred to this species are rather small, but the plant is easily recognized by its deflexed acumi- 

 nated lobules, and dentate stipules.
