Jungermannia berteroana, Hook., Bot. Misc., i. p. 148, t. 7s. 



Notarisia lycqpodioides, Colla in Mem. Accad. Sc Torino, xxxix. p. 53, t. 75, fig. 2? 



Juan Fernandez. Bertero ; Moseley. 



Barren stems of a smaller state were collected by Air W. Saunders' collector. It is 

 apparently confined to the island. 



We have added Notarisia as a synonym of this plant, after a comparison of the 

 descriptions and the inscription on Bertero's label, and there is little doubt that it is the 

 same. 



Radula microloba, Gottsche. 



Radula microloba, Gottsche in G. L. et N. Synopsis Hepat., p. 259. 



Juan Fernandez. Bertero; in a bad state on mosses, gathered by Mr W. 

 Saunders' collector. 



The species is very nearly allied to Radula pattens, Swartz. 



insertion of the leaves, both lobes are placed on the stem in a similar manner to those of some species of Marti- 

 nellia, the middle part of each lobe being attached higher up the stem than the angles and intermediate keel. 



Balantiopsis cequifolia, Mitt., n. sp. — Caulis ramis paucis remotis divisus ; folia densiuscide inserta, lobis dorsali- 

 bus et ventralibus sequalibus basi brevissime in carina coalitis ovatis apice sinu parvo angusto bidentatis 

 marginibus dentibus paucis spiniformibus ciliatis ; amphigastris ovah-rotundatis, apice lobis irregularibus brevibu.s 

 bispinosis et dentibus spiniformibus remotis ciliata. 



Caulis cum foliis T50 mm. latus. Folia fusco-alba. 



Habitat. — Port Churruca, Magellan ; inter Bruteliam repens, Cunningham. 



In the nearly equal size of the dorsal and ventral leaf-lobes and amphigastrium, equalling in size one of the 

 lobes, as 'well as in its fonn, this differs considerably from any of the others. 



Balantiopsis erinacea (Scapania, Taylor), differs at once from all the other known species in the two leaf- 

 lobes being free at their bases, as is figured, Fl. Ant., t. 161, iv. The outline of the leaf is, however, more 

 orbicular-ovate, bidentate at the point with ciliiform teeth all round. This came from the Falkland Islands. Very 

 incomplete specimens have since been sent from New Zealand, they are not quite certainly the same. Balantiopsis 

 dipiopJvylla {Scapania, Taylor), from New Zealand, is fairly represented in the figure Fl. Ant., t. G4, iv. ; 

 its lobes are connected as in Martinellia ; it is found also in Tasmania. Another species as it appears was sent 

 from New Zealand by Dr Knight, who sent also a sketch of its perianth, which agrees very nearly with a small 

 specimen gathered previously at New Plymouth, New Zealand. Balantiopsis lenightii, Mitt., n. sp. — Caulis 

 procumbens ; folia explanata, lobo ventrali subrotundo, oblonga, divergentia, apice tri quadridentata, lobo dorsali 

 minuto quadrate ovato apice bitridentato appresso, basi carina brevissima cum dorsale coalito, perianthio oblongo 

 cylindraceo radiculoso, capsula cylindracea, lobis demum in spiram contortis. 



This agrees in size with Balantiopsis diplophylla, but is in all the few specimens seen a shorter-stemmed 

 plant ; its dorsal leaf-lobe is so small that it is not wider than half the diameter of the stem, which is thus left 

 exposed ; in all the other species the stem is covered. The ventral lobe is quite entire except at the apex, where 

 it is provided with a few short teeth, thus differing from the spiniform teeth common to the other species. 



So far as can be seen in the specimens, the amphigastrium takes no part in the formation of the perianth, 

 which is in all the species terminal, the two leaves immediately next its orifice, but slightly modified in form. 

 All these species agree in their areolation of elongate limpid cells, and in this respect, as well as in the form 

 and insertion of the leaves, differ greatly from Tylimanthus ; and, indeed, from all the other genera which fruit 

 from a descending sac.
