FLORA OE NEW ZEALAND. 



\IIepatic<£. 



Eusco-rubra. Caulis parvus, gracilis, semipollicaris. Folia divergentia, lobulis magnis, dimidium folii aequanti- 

 bus, incumbentibus. Ampliigastria rotundata vel obovata. 



A small species, with the habit of the European F. dilatata ; it is, however, much less, and is easily known from 

 most others by the top of the lobule approaching the stem.— Plate CIV. Eig. 5 .—1, a stem, natural size; 2, a 

 portion of the same with leaves and stipule ; 3, a perianth with involucral leaves and stipule ; 4, a transverse section 

 of the perianth at about the middle. 



10. Erullania incumiens, Mitten; caule repente vage ramoso, foliis patentibus oblique obovatis apice 

 cucullato-incurvis lobulo oblougo incumbente cauli adpresso ore dilatato, amphigastriis late obovatis bifidis, 

 perianthio oblongo-obovato dorso piano ventre carinato, foliis involucralibus lobulo ovato-lanceolato uniden- 

 tato, ampliigastrio ovato bifido laciniis ovatis acutis. (Tab. CIV. Eig. 6.) 



Hab. Northern Island : bark of Mwardsia, Wairarapa valley ; East Coast and interior, Colenso. 



Olivaceo-viridis, fuscescens. Caulis semipollicaris. Folia imbricata, apice margineque ventrali supremo inflexo, 

 lobulo magno incumbente superne cauli adpresso. PerianiUum keve. 



In size and habit this species resembles F. dilatata, for its branches, although short, are rather stout. The in- 

 cumbent lobules have their upper parts closely applied to the ventral surface of the stem, and touch each other ; 

 so that when the stems are seen from below, they have an appearance very different from all allied species, ex- 

 cepting F.fngax, but from which, however, this is easily distinguished by the inflexed apices and upper portion of 

 the ventral margins of its patent leaves, by the much more incumbent lobule, and by the triquetrous form of its 

 perianth. — Plate CIV. Eig. 6 : 1, a stem, natural size; 2, a portion of the stem with leaves and stipule; 3, a pe- 

 rianth with involucral leaves and stipule; 4, a transverse section of the perianth taken from just above the middle : 

 — all magnified. 



11. Erullania pentapleura, Hook. fil. et Tayl. ; caule repente vage ramoso, foliis divergentibus rotun- 

 datis lobulo magno galeato paulo decurvo, amphigastriis parvis suborbiculatis bifidis margmibus integerrimis 

 vel repando-unidentatis, perianthio oblongo-ovato vel obcordato mucronato compresso dorso ventreque bica- 

 rinato marginibus carinisque undulatis repandis, foliis involucralibus ovatis lobuloque ovato unidentato 

 obtusiuscalis.— Lpnd. Joum. Bot. 1846, p. 402. G. L. et N. Syn. Hep. p. 775. (Tab. CIV. Eig. 7.) 



Hab. Northern Island : woods, Tarawera, Colenso. Auckland, Sinclair. 



Eusco-rubra vel subnigra. Caulis bi-tri-linearis, vage ramosus. Folia imbricata, apieibus parum incurvis, e 

 cellulis majusculis pellucidis areolata. Ampliigastria parva, caule latiora. Ferianthium carinis angustis undulato- 

 rcpandis. Spica masculcs lineares. 



This minute species has all the habit and appearance of F. fugax and of F. Fboracensis, Gottsche, of North 

 America, but it is distinguished from all its allies by its six-sided perianths ; its leaves have more pellucid and rather 

 larger cells than most of the New Zealand species which it nearly resembles. — Plate CIV. Eig. 7 : — 1, a stem, 

 natural size ; 2, a portion of the stem with leaves and stipule ; 3, a perianth with involucral leaves and stipule ; 4, 

 a transverse section of the perianth at the middle : — all magnified. 



12. Erullania congesta, Hook. fil. et Tayl, Flor. Infarct, p. 164. G. L. et K Syn. Hep. p. 451. 

 Hab. Northern Island: Titiokura forest, Tehawera, etc., Colenso. Auckland, Sinclair. Creeping 



over Lichens near Wellington, Stephenson (Herb. Mitten). 



13. Erullania aterrima, Hook. fil. et Tayl. ; perianthio obovato triquetro, foliis involucralibus longi- 

 oribus angustioribus acutis amphigastrioque profunde bifido laciniis acuminatis integerrimis.— -Flor. 

 Antarct. p. 164. t. 66./! 3. 



Hab. Northern Island : Beech-woods, etc., Wairarapa Valley, and Buahine mountains, Colenso. 

 Nearly as this species resembles F. congesta, it may be readily distinguished by the usually four-toothed stipules, 

 and by the presence of a cluster of enlarged cells at the base of the leaf near the ventral side.
