FLORA OF NEW ZEALAND. 



\_Hepaticee. 



Hab. Northern Island : Auckland, Sinclair. 



Pallide viridis, interdum fere albida. Caulis pollicaris, linearis, simplex, rariusve ramosus. Folia imbricata; 

 fere opposita, ut plurimum bidentata, dente marginis ventralis longiore, rarissime tridentata, e cellulis magnis mterstitns 

 grossiusculis areolata. Amphigastria parva, omnia conformia, cauli appressa. Perianthium, ssepe laterale, subsessile' 

 triquetral, angulo dorsali latius alatum, alis superne dentatis. Folia involucralia cum amphigastrio latiusculo coa- 

 lita, varie dentata. Odor plantse suavis, terebinthinus. 



The much larger cells of the leaves of this species afford a character by which it may be easily distinguished from 

 L. lenta and L. subporosa, which approach it in size ; the general appearance of the plants is more nearly that of some 

 small ChiloscypM. The specimens of L. midtipenna from Lord Auckland's Islands, and preserved in the Hookerian 

 Herbarium, appear to consist for the most part of sterile plants of Leioscyphus deeipiens, Mitten MSS. (a plant 

 which was also confounded with Lophocolea pallide-virens from Cape Horn), and a small white fertile state of Lo- 

 phocolea pallida, to which the description of the perianth belongs, whilst all that relates to the leaves and stipules 

 seems to have been taken from the first.

Caulis |-l-pollicaris. Folia explanata, vel sursum conniventia. AmpMgastria caule paulo latiora. Perian- 

 thium prismaticum, angulo dorsali latius alato, ala remote dentata. Folia perigonialia imbricata, adpressa, erecta, 

 basi ventricosa, apice squarrosa. 



This small species is a native of Lord Auckland's Group and of Fuegia, and agrees in habit with L. bidentata, 

 but is scarcely half its size, being scarcely larger than L. bicuspidata. The L. secundifolia of Flor. Antarct., and L. 

 diademata, Lond. Joum. Bot., although differing a little in appearance, do not present any character whereby they 

 can be distinguished, and to these might perhaps be added L. perpusilla. L. bispinosa agrees very nearly in all 

 other respects, but differs in its smaller areolation. Dr. Taylor describes the perianth as bilabiate, with the lips un- 

 equal ; but in all the plants here referred to L. diademata, as well as in the original specimens, the perianth is equally 

 trilabiate, as is usual in the genus, and seems to have each of the lips divided into two principal lacinise. — Plate

Of the plants here referred to L. bidentata, none possess any character of sufficient importance to distinguish 

 them from European states of that species. L. alternifolia and L. recurvifolia are without fruit. L. leptantha and 

 L. divaricata are states of L. bidentata in which the perianth is alate. The simply bifid stipules of L. recurvifolia 

 is not a constant character, nor is it rare to find plants of L. bidentata which have bifid stipules, and thin lower 

 parts. It may be reasonably inferred, from the remote habitats already recorded, that L. bidentata is cosmopolite. 



Lophocolea textilis, from Cape Horn, although possessing all the habit and appearance of L. bidentata, is proba- 

 bly a distinct species, the areolation being more lax, and the cells having a more vitreous look. I. humifusa, from
