Art. XXXII. — On some Additions to the Flora of the Mangonni Covnty. 



By H. Carse. 

 [Read before the Auckland Institute, 11th December, 1912.] 



Since my paper " On the Flora of the Mangonui County " was published 

 (Trans. N.Z. Inst., vol. 43, 1911), a few botanical discoveries worthy of note 

 have been made. 



Hypericum japonicum Thunb. 



Owing to a clerical error, I omitted this species from the catalogue of 

 plants. It is not uncommon in damp places. 



Corokia Cheesemanii Carse sp. no v. 



Corokia pps. sp. nov. Carse, Trans. N.Z. Inst., vol. 43, p. 201, 191). 



In my paper I referred to this, mentioning that it was probably similar 

 to one foimd by Mr. Cheeseman in the North Cape district. I had not 

 then seen specimens of Mr. Cheeseman's plant, nor flowering specimens 

 of the Tauroa plant. I have recently been able to compare the two and 

 am convinced that they are identical, and also that they are markedly 

 different from the already acknowledged species. I have much pleasure, 

 therefore, in dedicating the new species to Mr. Cheeseman, its original 

 discoverer. The specific description is as follows : — 



Frutex erectus, ramosus, l-5-3-5m. altus. Rami graciles, foliosi, non 

 tortuosi nee intertexti ; ramulis, foliis subtus, et inflorescentia argenteo- 

 tomentosis. Folia alterna, 3-5 cm. longa, elliptico-oblonga vel oblongo- 

 lanceolata, petiolis brevissimis. Flores fasciculati vel in paniculas ter- 

 minales paucifloras dispositi, circa 10 mm. diam., petalis oblongo-lanceolatis. 

 Drupae oblongae, 7 mm. diam., 10 mm. longae, rubrae. 



Z?a6.— North Island : Spirits Bay, North Cape district ; T.F.C.! Tauroa, 

 in woods ; H. B. Matthews ! H.C. 



Flower's : October-November. 



A slender shrub, l-5-3-5m. high. Branches spreading, not tortuous 

 nor interlacing as in C. cotoneaster. Young shoots, under-surface of leaves, 

 and inflorescence densely clothed with silvery- white tomentum. Leaves 

 alternate, 3-5-5 cm. long, elliptic-oblong to oblong-lanceolate. Petioles 

 very short, or lengthened and flattened, as in C. cotoneaster. Flowers similar 

 to those of C. cotoneaster, but narrower in the petals, in fascicles of 2-4 in 

 the axils of the leaves or of small branches, or in terminal panicles. Drupe 

 obovoid-oblong or oblong, 7 mm. in diameter, 10 mm. long. 



This description applies to the type specimens, but the plant appears 

 to pass by regular gradations into C. cotoneaster on the one hand, and into 

 C. huddleoides on the other, with a tendency in one form to a broadening 

 of the leaves, bringing the species very close to the Chatham Island 

 C. macrocarpa. At present I have not seen the fruit of the last-mentioned 

 form. 



The typical form is very distinct. From C. huddleoides it differs in its 

 smaller size, smaller and proportionally broader leaves, which are usually 

 more obtuse, in the fewer-flowered and less-leafy panicles. From C. cotone- 

 aster it is distinguished by the absence of tortuous and interlacing branches.
