South Island : Marlborough — Clarence Valley, near the coast. Named 

 in honour of the late Mr. H. J. Matthews, the discoverer of the plant. 



W . Matihewsii is related to W. vincaefiora Dene. (= W. gracilis A.D.G.), 

 but is amply distinct in the. numerous, close-set, linear leaves, invariable 

 in form, the purplish erect, simple or sparingly branching stems given off 

 closely together from a woody rootstock, and the large pale-lilac flowers.

South Island : Canterbury — In fellfield or steppe from the lower sub- 

 alpine to the alpine belts on mountains drained by the River Waimakariri. 

 but not where the rainfall is excessive. L. C. 



This rather critical species was included by Cheeseman in C. discolor 

 Hook, f., an aggregate species containing a most diverse set of plants. This 

 the description clearly shows — e.g., " Leaves very variable in size and shape. 

 1-2J in. long, j— \ in. wide, oblong-spathulate to linear, obtuse or acute, 

 entire or serrulate, very coriaceous to almost membranous, viscid, glabrouf. 

 or hoary above " ; " broad or narrow at the base, sometimes almost 

 petiolate." (Manual, p. 304.) 



A .study, however, of the " species " in the field shows that certain forms 

 are constant over considerable areas, and that the prevailing form of one 

 locality is quite absent in others. There are, in fact, various groups of 

 individuals with constant and distinct characters which, in time, will 

 undoubtedly receive distinct names, either specific or varietal ; and this 

 does not apply to C. discolor merely, but to C. inca.na, C. longi folia, and 

 other aggregate species. 



C. angustifolia, as here defined, is an exceedingly common plant in the 

 drier mountains drained by the River Waimakariri, where, so far as I know, 

 there are no transitions to the forms of C. discolor with oblong-spathulate 

 leaves, so common farther to the south. Such variation as does occur is 

 solely environmental and exhibited for the most part in reduction in size 

 of the aereal organs. 



The only doubt I feel in publishing the species is not whether it is well 

 to split up the aggregate C. discolor either into species or varieties, but 

 whether Erigeron novae-zealandiae Buch. is not the same plant. The re- 

 semblance between the two was pointed out to me by Mr. D. Petrie ; con- 

 sequently I have carefully compared Buchanan's drawing and description 

 with my specimens of the Waimakariri plant, and have come to the con- 

 clusion that the two are not the same. If, however, plants matching
