11. Lophocolea Colensoi, Mitten; canle repente vage ramoso, foliis imbricatis ovato-oblongis integer- 

 rimis apice truncato-bidentatis, amphigastriis profande bipartite segmentis extus bidentatis basi utrinque 

 folio inferiore coalitis. (Tab. XCVII. Fig. 6.) 



Hab. Northern Island : on rotten wood, East Coast, Colenso. 



Pusco-virens. Caulk bi-triuncialis. Folia explanata, breviter bidentata, interdum dentibus obsoletis. Am- 

 pJiigastria sex- rarius quadri-dentata. 



The largest Lophocolea yet known ; the specimens owe their fine appearance, in part, to having grown on de- 

 cayed wood ; a circumstance which usually increases the size of the European species. The present is allied to L. 

 pallide-virens [Chiloscyphus, Flor. Antarct. t. 159.'/. 9], but the leaves are of a different form, and their apices 

 wider. In L. pallide-virens the stipules are narrowly decurrent on both sides into the subjacent leaves, and the 

 perianths are occasionally terminal; but the lateral perianths are altogether those of Lophocolea, and in this respect 

 it corresponds with some states of L. bidentata. The L. Beecheyana, Taylor, from Oahu, differs from L. connata, 

 Sw., in its involucral leaves and stipule being furnished with numerous ciliiform teeth. L. humistrata, Tayl., 

 from St. Helena, has its leaves truncate at their apices, and mostly without the spiniform teeth ; yet both this and 

 the preceding are so closely allied to L. connata in all other respects, that it may be doubted if they are not mere 

 forms of that species.— Plate XCVII. Pig. 6 :— 1, a plant, natural size; 3, a portion of the stem with leaves and 

 stipule : — magnified. 



12. Lophocolea trkcantha, Hook. fil. et Tayl.; caule implexo repente vage ramoso, foliis patentibus 

 complanatis adproximatis basi late adnatis snbdecurrentibus ovato-quadratis tricuspidatis, amphigastriis 

 palmato-quadrifidis segmentis setaccis.— Land. Joum. Bot. 1846, p. 386. G. L. et N. Syn. Hep. p. 698. 

 (Tab. XCVII. Kg. 7.) 



Hab. Northern and Middle Islands : Akaroa, Baoul. Hills, Pahiatna, Colenso. 



Pallide virens vel fusceseens. Caulis biuncialis, paree ramosus. Folia explanata, late ovata. Amphigastria 

 parva, uno latere in folium inferius anguste decurrentia. 



This species is readily distinguished from all its congeners, by its trispinose leaves. In habit it agrees nearly 

 with L. bidentata, but no fructification has been seen. It has considerable resemblance to OMloscypMs combinatus, 

 Nees, but its leaves are of a thinner texture, and the teeth are more slender and longer ; in the same respects it also 

 differs from C. Fndlicherianus, Nees.— Plate XCVII. Pig. 7 :— 1, a plant, natural size; 2, a portion of the stem 

 with leaves and stipule : — magnified. 



13. Lophocolea leucopliylla, Tayl., G. L. et N. Syn. Hep. p. 155. Chiloscyphus leucophyllus, Hook, 

 fil. et Tayl. in Land. Joum. Bot. 1844,^. 384. Flor. Antarct. p. 157. t. 65.,/. 4. G. L. el N. Syn. Hep. 

 'p. 181 et 706. 



Hab. Northern Island : top of Ruahine mountains, Colenso. 



A curious species, of which the New Zealand specimens are very much finer than those from Lord Auckland's 

 Islands, and in some elongated stems are three inches high. The perianth is triquetrous and terminal, its lacinise 

 rather obtuse, entire, the margin denticulate, The involucral leaves and stipule differ little from those of the stem. 

 Excepting therefore the papillose surface of its leaves, this species is allied to L. GaudicJumdii, Mont., from the 

 Sandwich Islands, L. Columbica, Gottsche, and L. Orbigniana, Nees et Mont., from Peru and Bolivia. It appears to 

 be exceedingly variable in size, some stems being scarcely half an inch high, and slender or stout, but the specific 

 characters appear to be very constant.
