404 SUBANTARCTIC ISLANDS OF NEW ZEALAND. [Systematic Botany. 



This is one of the few species found on nearly all the widely scattered islands — 

 specks in a vast ocean — which girdle the globe between lat. 50° and 60° S., although, 

 curiously enough, it does not occur on the Auckland and Campbell Islands. Hooker 

 associated with it a plant not uncommon in subalpine localities in the South Island, 

 but a comparison with specimens from Macquarie and Kerguelen Island show several 

 important differences, and I suspect that the New Zealand plant will constitute a 

 separate species. 



Crassulaoeae. 

 Tillaea moschata, D.C. 



Crassula moschata, Forst. in Comm. Gott., ix, 26 (1789). Bulliarda mos- 

 chata, D'Urv., Fl. Malouines in Mem. Soc. Linn. Paris, iv, 618 (1826) ; 

 Hook, f., Fl. Antarct., i, 15 (1844). Tillaea moschata, D.C, Prodr,, 

 iii, 382 (1828). 



The Snares : Kirk, Aston. Auckland and Campbell Islands : Maritime rocks, 

 abundant ; Hooker, Kirk ! Cockayne, Laing ! Aston ! Tennant ! Antipodes Island : 

 Kirk. Macquarie Island : Maritime rocks ; Scott, Hamilton. (New Zealand, from 

 Cook Strait southwards ; Fuegia ; Falkland Islands ; Kerguelen Island ; Marion 

 Island.) 



One of the commonest plants of the islands, almost invariably present on mari- 

 time rocks and cliffs. 



Droseraceae. 

 Drosera stenopetala, Hook. f. 



Drosera sp.. Hook, f., Fl. Antarct., i, 8 (1844). D. stenopetala. Hook, f., 

 Fl. Nov. Zel., i, 19, t. 9 (1853). 



Auckland Islands : Hooker, Le Guillon (" Flora Antarctica," ii, 246), Kirk, 

 Cockayne, Tennant ! Campbell Island : Peat bogs ; Laing ! (Mountain districts 

 in New Zealand, from the Ruahine Range southwards.) 



My specimens are all immature, and show no trace of flowers, but are apparently 

 referable to this species. 



Haloragaceae. 



Haloragis micrantha, R. Br. ex Sieb. & Zucc, Fl. Jap. 



Haloragis micrantha, R. Br. ex Sieb. & Zucc, Fl. Jap. i. 25 (1815) ; Hook, f., 

 Handb. N.Z., FL, 66 (1864). 



Auckland Islands : Head of Norman's Inlet ; Laing ! (Throughout New Zea- 

 land ; eastern Australia, and Tasmania ; Malaya ; China ; Japan.) 



This is an addition to the florula of the islands. The specimens are mere scraps, 

 but there seems to be no reason to doubt their identity with the well-known H. 

 micrantha. 



Callitriche antarctica, Engelm. 



Callitriche verna. Hook, f., Fl. Antarct., i, 11, non Linn. ; also, var. tenestris, 

 I.e. (1844). C. antarctica, Engelm. ex Hegelm. in Verh. Bot. Ver. 

 Brand., ix, 20 (1867).
