Corysanthes triloba, Hook. f. 



Nematoceras triloba, Hook, f., Fl. Nov. Zel., i, 250 (1853). Corysanthes 

 triloba, Hook, f., Handb. N.Z. FL, 265 (1864). 



Auckland Islands : Camp Cove ; Aston ! Campbell Island : Laing ! Chambers ! 

 (New Zealand, shaded places from the North Cape southwards.) 



This is an addition to the florula of the southern islands. Mr. Laing's speci- 

 mens, preserved in formalin, clearly show the characteristic obtuse upper sepal. 

 C. macrantha, which is sometimes difficult to separate from C. triloba, always has an 

 acute or acuminate upper sepal. 



Corysanthes macrantha, Hook. f. 



Nematoceras macrantha. Hook, f., Fl. Nov. Zel., i, 249 (1853). Corysanthes 

 macrantha, Hook, f., Handb. N.Z. FL, 266 (1864). 



Auckland and Campbell Islands : Shaded mossy places, not uncommon ; Bolton, 

 Aston ! Tennant ! Laing ! 



Corresponds with New Zealand specimens. 



LiLIACEAE. 



Astelia linearis. Hook. f. 



Astelia linearis. Hook, f., Fl. Antarct., i, 76 (1844). 



Auckland and Campbell Islands : Abundant in open places ; Hooker and all 

 subsequent collectors, (New Zealand, upland districts from the East Cape and 

 Ruapehu southwards.) 



This is represented in Fuegia by the closely allied A. fumila, R. Br., and in 

 Victoria and Tasmania by the broader-leaved A. alfina, R. Br. Auckland Island 

 specimens agree well with the ordinary form of the species in New Zealand. 



Astelia subulata, Cheesem., n. sp. 



Astelia linearis, var. subulata, Hook, f., Fl. Antarct., i, 76 (1844). 



Herba pusilla, densissime caespitosa, habitu A. lineari sed multo minor. Folia 

 minora, erecta vel paullo curvata, 1 •5-2-5 cm. longa, 0-5-0 -75 mm. lata, subulata, 

 teretia vel superne obscure canaliculata, versus apicem cylindracea ; vaginae mem- 

 branaceae, hyalinae, paleis argenteis obtectae. Scapus solitarius, terminalis, bre- 

 visissimus. Flos solitarius, terminalis, simiUimus ad A. lineari sed minor. Fructus 

 ignotus. 



Auckland and Campbell Islands : Wet open places on the hills, not uncommon ; 

 Hooker, Cockayne, Aston ! Tennant ! Laing ! (Endemic.) 



This differs so much in foliage from all the states of A. linearis that I am 

 acquainted with that I feel compelled to grant it the rank of a species. A. linearis 

 has leaves varying from 1-8 in. long by -^^--^va.. broad, channelled above and keeled 

 below, more or less sulcate or grooved, and with the midrib and margins clothed 

 with narrow hyaline scales. In A. subulata the leaves are seldom over \ in. long 

 by Jq in. broad, terete or slightly flattened or canaliculate above, smooth, quite 

 glabrous except the sheaths. I have seen only very imperfect flowering specimens,
