Hymenophyllum Tunbridgense, Smith. 



Trichomanes Tunbridgense, Linn., Sp. Plant., 1098 (1753). Hymeno'phyllum 

 Tunbridgense, Smith, Engl. Bot., t. 162 (1794) ; Hook, f., Handb. 

 N.Z. Fl., 352 (1864). 



Auckland Islands : Hooker. (Most temperate and subtropical countries.) 



This is anoth ^r fern of which I have seen no specimens from the southern islands. 



It has been included in the lists on the authority of Hooker's Handbook, where 



" Lord Auckland's Group " is quoted as a locality ; but if this is correct it is singular 



that it is not included in the enumeration of species given in the " Flora Antarctica." 



Hymenophyllum multifidum, Swartz. 



Trichomanes multifidum, Forst., Prodr., n. 473 (1786). Hymenophyllum 

 multifidum, Swartz, Syn. Fil., 146, 378 (1806) ; Hook, f., Fl. Antarct., 

 i, 104 (1844). 



Auckland and Campbell Islands : " In all situations, from the level of the sea 

 to the tops of the mountains, growing on the ground, on trunks of trees, and on 

 rocks " ; Hooker and all subsequent collectors. Antipodes Island : Kirk ! Cockayne. 

 (Throughout New Zealand ; New South Wales ; Polynesia ; Malaysia.) 



This is the most abundant species of the genus in the southern islands, and has 

 a wonderful range of habitats. When growing in open places, amongst rocks or 

 grass, the fronds are often curved downwards, and the pinnae rolled inwards, so 

 that the appearance of the species is very different from that which it assumes when 

 growing in woods. 



Hymenophyllum bivalve, Swartz. 



Trichomanes bivalve, Forst., Prodr., n. 466 (1786) ; Hymenophyllum bivalve, 

 Swartz, Syn. Fil., 146, 372 (1806) ; Hook, f., Handb. N.Z. FL, 353 

 (1864) ; T. Kirk in Eeport Austral. Assoc, iii, 222 (1891). 



Auckland Islands : Port Ross ; Kirk ! (New Zealand, from Cape Colville south- 

 wards ; New South Wales.) 



I have seen no specimens but Mr. Kirk's. 



Hemitelia Smithii, Hook. 



Cyathea Smithii, Hook, f,, Fl. Nov. Zel., ii, 8, t. 72 (1853). Hemitelia 

 Smithii, Hook., Syn. Fil., 31 (1874); Cockayne in Trans. N.Z. Inst., 

 xxxvi, 246 (1904). 



Auckland Islands : Rata forest, Norman's Inlet ; Joss and Cockayne ! 

 (Throughout New Zealand.) 



The discovery of this species in the Auckland Islands, first recorded by Dr. 

 Cockayne in his paper on " A Botanical Excursion to the Southern Islands " (Trans. 

 N.Z. Inst., xxxvi, 246), is of considerable interest from the point of view of botanical 

 geography, as it advances the known southern limit of tree-ferns by rather more 

 than 2 degrees.
