432 SUBANTARCTIC ISLANDS OF NEW ZEALAND. [Systematic Botany. 



Luzula campestris, D.C., var. crinita, Buchen. 



Luzula crinita, Hook, f., Fl. Antarct., i, 84, t. 48 (1844) ; Handb. N.Z. Fl., 

 293 (1864). L. campestris, D.C., var. crinita, Buchen. in Oesterr. Bot. 

 Zeit., 215 (1898). 



Auckland and Campbell Islands : Not uncommon from sea-level to the sum- 

 mits of the hills ; Hooker and all subsequent collectors. Antipodes Island : Kirk ! 

 Macquarie Island : Fraser, Scott, Hamilton. (Endemic.) 



The distinguishing characters of this variety are the very robust and firm, some- 

 times almost rigid, habit ; leaves with the margins distinctly thickened and furnished 

 with very long but somewhat distantly placed cilia ; inflorescence often composed 

 of a single conglobate head, but sometimes with 1-3 lateral heads ; and very dark- 

 chestnut bracts, which are usually most densely ciliate. 



Luzula campestris, D.C., var. floribunda, Buchen. 



Luzula campestris, D.C., var. floribunda, Buchen. in " Pflanzenreich," heft 

 25, 93 (1906). 



Auckland Islands : Port Ross; Aston! Tennant ! (New Zealand.) 



Differs from any form of the preceding in the much less rigid habit, much 

 broader and thinner leaves (sometimes 8 mm. diam.), and especially in the greatly 

 developed inflorescence, which consists of very numerous (in one of Mr. Aston's 

 specimens over thirty) pedunculate heads arranged in an umbellate manner, and in 

 the paler bracts, with almost white margins. The Auckland Island plant suits the 

 description of var. floribunda better than any other, and comes very close to some 

 South Island mountain forms collected by myself which Buchenau includes in the 

 variety. 



Centrolepidaceae. 



Gaimardia ciliata, Hook. f. 



Gaimardia ciliata, Hook, f., Fl. Antarct., i, 85 (1844). Centrolepis viridis, 

 T. Kirk in Trans. N.Z. Inst., xxiii, 441 (1891). Alepyrum ciliatum, 

 Hieron., Pflanzenf., teil ii, abt. 4, 13 (1895). 



Auckland and Campbell Islands : Abundant in boggy places, in open situations ; 

 Hooker ! Kirk ! Cockayne, Aston ! Laing ! Chambers ! (New Zealand, upland bogs 

 from Puapehu southwards,) 



I do not think that either this or the following species ought to be placed in 

 Centrolepis, as has been done by Kirk and other authors. As pointed out in the 

 Manual, they diiJer in the perennial densely pulvinate habit, the shape of the leaves, 

 the flowers seldom more than one in each floral bract, and in the cells of the ovary 

 or carpels) being frequently reduced to one. In the " Pflanzenf a milien " Hieronymus 

 keeps up the genus Alepyrum for their reception, a course which is likely to lead to 

 confusion, seeing that not one of the species which Robert Brown placed in the 

 original genus Alepyrum is retained in it by Hieronymus. Until the whole family 

 receives a careful examination it is best to leave the species in Gaimardia.
