involucralibus lanceolatis acutis, lobulo lanceolato-subulato extus unidentato, ampliigastrio sinu lato ro- 

 tundo bifido laciniis lanceolatis. — Lond. Joum. Bot. 1846, j». 407. G. L. et N. Syn. Hep. I.e. (Tab. CIV. 

 Fig. 2.) 



Hab. Northern Island : Auckland, Sinclair. Bark of trees, Tehawera forest, Colenso. 



Fusco-viridis. Caulis 1-lij-pollicaris. Folia subremota, lobulo parvo uncinate subcompresso vel explanato erecto. 

 PeriantMum tumidum, Irigono-cylindrioum, apice subretuso mucronato. 



A very distinct species, readily recognized by its small hooked lobules and inflated subcylindrical perianths. In 

 size it comes near to F. cyparoides (Schw.).— Plate CIV. Fig. 2 : — 1, a stem, natural size ; 2, a portion of the same 

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

 section of the perianth : — all magnified. 



7. Frullania deplanata, Mitten; caule repente pinnatim ramoso, foliis imbricatis ovatis obtusis apice 

 incurvis lobulo magno galeasformi compresso decurvo, amphigastriis suborbiculatis breviter bifidis, perianthio 

 elongato obcordato deplanato Isevi, foliis involucralibus ovatis acutis integerrimis repando-dentatisve lobulo 

 lanceolato extus dentato, ampbigastrio elongato apice laciniato dentato. (Tab. CIV. Fig. 3.) 



Hab. Northern Island: on Lichens near Wellington, Stephenson (Herb. Mitten). Bark of trees, 

 East Coast and interior, abundant, Colenso. 



Fusco-rubra. Caulis pollicaris, repens. Folia divergentia, lobulis apicibus decurvis. AmpMgastria apice pa- 

 tula, brevissime bidentata. PeriantMum superne deplanatum, retusum, mucronatum. 



This somewhat resembles a small state of F. falciloba, in the form of its leaves and decurved lobules, but in its 

 perianth is different from that of every other species, corresponding with certain species of Lejeunia. The plants are 

 closely creeping, and in some states the perianth has its apex bent downwards. — Plate CIV. Fig. 3 : — 1, a stem, 

 natural size ; 2, a portion of the same, with leaves and stipule ; 3, a perianth, with involucral leaves and stipule, as 

 seen on the ventral side ; 4, a transverse section of the perianth : — all magnified. 



8. Frullania reptans, Mitten; caule repente pinnatim ramoso, foliis obovatis divergentibus lobulis 

 magnis galeatis subcompressis, amphigastriis parvis cuneatis quadridentatis, perianthio oblongo-ovato sub- 

 obtuso mucronato dorso planiusculo ventreque convexo anguste quadricarinato marginibus carinisque su- 

 perne subrepando-dentatis, foliis involucralibus ovatis rotundatis lobulo lanceolato extus unidentato, am- 

 phigastrio bifido extus utrinque unidentato. (Tab. CIV. Fig. 4.) 



Hab. Northern Island : bark of Edwardsia, East Coast, Colenso. 



Sordide olivacea vel subnigra. Caulis exilis, semipollicaris, repens, pinnatim vage ramosus, vel cajspitosus. 

 Folia laxe imbricata, lobulo dimidmm folii eequante. AmpMgastria cuneata vel obovata, bifida. PeriantMum ob- 

 longo-ovatum, basi attenuatum, dorso carinis mediis altioribus marginibus repandis fere lssvibus. 



A smaller species than F. fugacc, with lobules like F. dilatata. The perianths, which are very different from 

 those of its near allies, have here and there along their margins and carinas a cell more prominent than the rest. — 

 Plate CIV. Fig. 4 : — 1, stems, natural size; 2, a portion of the same with leaves and stipule; 3, a perianth, invo- 

 lucral leaves, and stipule ; 4, a transverse section, from a little above the middle of the perianth : — all magnified. 



9. Frullania fugax, Hook. fil. et Tayl. ; caule repente vage subpinnatim ramoso, foliis imbricatis ro- 

 tundatis lobulis magnis rotundo-ovalibus ore paullo dilatatis superne incumbentibus, amphigastriis parvis 

 subrotundis bifidis laciniis integerrimis vel repando-unidentatis, perianthio obovato apiculato dorso planius- 

 culo obtuso bicarinato ventre latissime carinato, foliis involucralibus elongatis obtusis lobulo lanceolato, 

 ampliigastrio lanceolato bifido laciniis acutis integerrimis vel repando-dentatis. — Lond. Joum. Bot. 1845, 

 p. 87. G. L. el N. Syn. Hep. p. 445. (Tab. CIV. Fig. 5.)
