L. CocKATNE. — Notes 071 New Zealand Floristic Botnny, 197 



South Island : Marlborough — In soil on rock, Inland Kaikoura Moun- 

 tains, at about 1,000 m. altitude ; C. E. Foweraker and L. C. 



This plant is related, on the one hand, to H. hellidioides Hook, f., from 

 which it differs in its more erect habit, softer leaves tomentose on both sur- 

 faces, much smaller flower-heads, and at times branched flowering-stems ; 

 and, on the other hand, to H. Sinclairii Hook, f., which it resembles greatly 

 in the leaves and somewhat in habit, but has a very different inflorescence 

 and flower-heads. 



Only one plant was observed, so it is possibly extremely rare. Its 

 resemblance to the above two species hints at a hybrid origin. 



7. Lagenophora pinnatifida Hook. f. 



There appear to be two well-marked varieties of this species, which 

 can be distinguished at a glance by differences in the texture and degree 

 of hairiness of the leaf, the extent of indentation of its margin, and the 

 relative size of the flower-heads. The following are diagnoses of these two 

 undescribed varieties, which together make up the aggregate species 

 Lagenophora pinnatifida : — 



(a.) Lagenophora pinnatifida Hook. f. var. hirsutissima Cockayne var. 

 nov. 



Folia pilis albis hirsutis densissime utrinque obtecta, grosse crenato- 

 dentata ; capitula circ. 12 mm. diametro. 



North Island : Hawke's Bay — -Upper part of Wairoa River ; T. Kirk ! 

 South Island : Fairly common in eastern Nothofagus forest, especially of 

 montane belt from Nelson to Otago ; Cheeseman, L. C, and others. 



The leaves are most thickly covered with, soft white hairs, so that the 

 surface is concealed ; the margin is deeply and coarsely crenate-dentate ; 

 and the heads are about 12 mm. diameter, and borne on straight scapes 

 about 10 cm. long. 



The northern plant described below looked so different from that of ' 

 the south when, in company with Mr. H. Carse, I first saw it in its 

 habitat that I considered it a distinct species. For this reason, looking 

 upon it, in error probably, as the type of L. pinnatifida Hook, f., in my 

 " Vegetation of New Zealand " I have given the MS. name L. sylvestris to 

 the plant of the South Island. However, it seems best, in view of the 

 close affinity of the two races, to treat them as varieties of an aggregate 

 rather than as distinct species. 



(&.) Lagenophora pinnatifida Hook. f. var. tenuifolia Cockayne var. nov. 



Planta a varietate hirsuta differt foliis tenuoribus, aliquando sub- 

 integerrimis pilis brevioribus hand dense obtectis, capitulis minoribus. 



North Island : Auckland — -Tauroa, Mongonui County; H. Carse ! L. C. 



This variety is separated from var. hirsutissinm by its thinner, some- 

 times almost entire leaves, which are never very deeply cut, their surfaces 

 much less densely covered with shorter hairs, and the smaller flower-heads. 

 In some specimens the leaves are considerably broader than any I have 

 seen of var. hirsutissima. 



8. Ourisia calycina Colenso. 



In 1889 Colenso described a species of Ourisia collected on " highlands 

 on River Waimakariri, near Bealey, South Island " (which probably means 

 Arthur's Pass), " by a visitor and sent to Napier " (Trans. N.Z. Inst., vol. 21, 

 pp. 97-98). The description clearly shows that the plant in question was
