HEPATIC^. 1 



Plagiochila badia, Mitt., n. sp. 



Caulis elongatus; parce ramosus ; folia approximata, pateutia, patulave ovato-oblonga, 

 inargiue dorsali decurrente recurva, ventralique iutegerrima, apice breviter paucidentata. 



Habitus staturaque Plagiochilce, rubescentis, Linden b., t. xi., et foliorum ambitu similis, 

 sed margine ventrali integerrima, apice dentibus brevissimis armata subintegerrima. 

 Color nio-ro-fusca.

Juan Fernandez. Mr W. Saunders collector. 



At first sight the specimens of this species might readily be mistaken for Plagiochila 

 rubescens,- which has often the same dark colour; but the entire absence of the ciliiform 

 teeth at once distinguishes it. Like Plagiochila rubescens, the foliage is scarcely altered in 

 the dry state, and it is here and there glossy. 



Plagiochila gayana, Gottsche. 



Plagiochila gayana, Gottsche in Ann. Sci. Nat., ser. 4, viii. p. 322. 



Juan Fernandez. — From the same source as the preceding. 



A small-leaved species similar to Plagiochila gcniculata, Lindenb., t. xxvii., in size and 

 appearance, but quite distinct in the perianth, which is much compressed and with a small 

 contracted truncate moutb, a form that is very rare in the genus. There is considerable 

 variation in the dentation of the ventral niaro-in of the leaf : on some stems the leaves are 

 almost entire, slightly angulate ; in other plants they are, as described by Gottsche, dentate 

 all round the ventral side ; the areolation is of small round cells with wide walls, the whole 

 almost obscure. It is also very similar to Plagiochila jlexicaulis, Mont., from Chili; but 

 readily distinguished by the perianth. 



Lophocolea sylvatica, Mitt., n. sp. 



Prostrata ; folia horizontaliter explanata, convexula, ovali-oblonga, apice sinu obtuso 

 biangulata ; amphigastria parva, quadridentata, utrinque cum foliis anguste conflueutes ; 

 involucralia longiora, cum amphigastrio integerrimo apice bidentato basi coalita ; peri- 

 anthium triquetrum, labiis dentatis. 



Caulis 1-2 cm. longus, hie illic radicosus cum foliis 2 mm. latus ; amphigastria 

 caulem vix latiora saepe recurva. Periantbium 1'50 mm. longum, angulis nudis.
