440 Transactions. — Botany. 



Flowers perfect, minute, in lax elongating terminal 

 racemes. Sepals small, rounded, green, with scarious edges ; 

 petals narrow-linear-spathulate, as long as the sepals ; sta- 

 mens slender, twice the length of the sepals, or less. 



Pods on slender pedicels not exceeding their own length, 

 sub-orbicular, but sensibly acute at the apex ; apical notch 

 narrow, filled up by the short style. 



Hah. Gimmerburn district, Maniototo Plain ; 1,100ft. 



A most distinct plant. Its small size, prostrate habit, and 

 short linear entire leaves mark it off from all the other native 

 species. It is named in compliment to T. Kirk, Esq., F.L.S., 

 who has published an important paper on the New Zealand 

 species of the genus. 



3. Aci'phylla simplex, nov. sp. 



A branched, prostrate species, forming compact patches 

 like A. dobsoni, Hook. f. 



Stems slender, more or less branched, most densely 

 clothed with simple closely-imbricating leaves. 



Leaves lfin.-3in. long; the lower half expanded into a 

 thin but stifi' sheath ^in. wide ; the blade simple, linear-sub- 

 ulate, jointed, semiterete, concave or channelled above, with 

 an ill-defined midrib on the under-surface that frequently 

 projects as a short, Ijlunt, or pungent mucro. 



Flowering-stem as stout as the leaves, l-|iu.-3in. long, 

 striate, bearing at its top two small leaves like the radical and 

 four or five short densely-capitate umbels of flow^ers. 



Mature achenes not seen. 



Hab. Mount Pisa, Mount Cardrona, and Hector Mountains, 

 6,000ft., on broken rock. 



This species is very close to A. dobsoni, Hook, f., from 

 which, as well as from all its congeners, it is clearly distin- 

 guished by its simple linear-subulate leaves. It flowers in 

 February. 



4. Helichrysum ijwrdiei, nov. sp. 



A much-branched, prostrate, spreading species. 



Stems lift. -2ft. long, rigid and woody below, the ultimate 

 twigs wiry, very slender, and clothed with fine loose white 

 tomentum. 



Leaves alternate, at intervals of iin.-^in., uniform in 

 texture and outline, membranous, ^in.-^in. long, obovate- 

 spathulate, bluntly rounded at the apex and abruptly apicu- 

 late ; upper surface reticulate and pubescent (in old leaves 

 nearly glabrous) ; under-surface densely clothed with loosely- 

 appressed greyish-white tomentum concealing the midrib and 

 nerves ; the margin recurved. 



Inflorescence corymbose, of 3 to 6 small heads, with
