I. Ranunculaceæ.

4 Clematis parviflora.— To this species I refer with some doubt C. Hillii, Col. in Trans. N.Z. Inst. xxxi. (1899) 266, of which I have seen no authentically named specimens.
6 Myosurus aristatus.—Abundant in moist places near the mouth of the Awatere River, Marlborough, J. H. Macmahon I
10 2 bis. Ranunculus Matthewsii, Cheesem. n. sp.—Habit of B. Buchanani, but larger and stouter, 15–20 in. high, glabrous or with a few weak hairs on the petioles and peduncles. Radical leaves on stout petioles 3–9 in. long, reniform or orbicular in outline, ternatisect; the main divisions petiolate, coarsely toothed or lobed. Cauline leaves sessile, deeply toothed or lobed, but not so finely as in R. Buchanani. Flowers 1–4, large, pure-white, sweet-scented, 2½–3 in. diam. Sepals 5, slightly villous, reflexed when the flower is mature. Petals numerous, 12–20, oblong-cuneate, rounded at the tip, narrowed to the base; gland solitary, large, basilar. Achenes turgid, pilose, forming an oblong-globose bead ½in. diam. or more; styles long, subulate.
South Island: Otago — Mount Earnslaw, alt. 4000–6000 ft., H. J. Matthews!
I have only two good specimens of this beautiful plant, and some allowance must consequently be made for the description. It is evidently very close to R. Buchanani, differing chiefly in the larger size and stouter habit, in being almost glabrous, and in the more sparingly divided leaves and larger flowers.
12 R. nivicola.—Mount Holdsworth, Tararua Range, W. Townson! Flowerless specimens apparently belonging to the same species have also been sent from Mount Stokes, Marlborough, by Mr. J. H. Macmahon.
14 R. tenuicaulis.—Boundary Peak, Lyell District, alt. 3000–4000 ft., W. Townson I Sources of the Poulter River and Kelly's Hill, Westland, Dr. Cockayne.
22 R. Hectori.—Dr. Cockayne considers that this is doubtfully distinct from R. aucklandicus. (See Trans. N.Z. Inst. xxxvii. 318.)
25 R. rivularis.—According to Kirk's Students' Flora, Petrie's R. areolatus (Trans. N.Z. Inst. xxii. (1891) 439) is based upon a mixture of this species and the Scandinavian R. pygmœus, Wahlb.
