alt. 2000 ft., Sinclair ; Otago, Lake district, Hector and Buchanan. 
4. A. Buchanani, Hook. /., n. sp. Habit and size of A. microphylla , 
but the young branches petioles and calyx are villous with silky hairs : flowers 
much fewer in a head, spines of the calyx curved, yellow, usually with a few 
bristles at the tip. Stigma elongate, dilated upwards, fimbriate. Stamen 1. 
Achenes bony. 
Middle Island : Otago, lake district, Hector and Buchanan. Foliage very pale. As 
iu A. microphylla , the fruiting calyx is sometimes not spiuescent. 
5. A. inermis, Hook. f. FI. N. Z. i. 54. Small, prostrate, slightly 
silky, tufted, much-branched below. Leaves 1-4 in. long ; leaflets 4-6 pairs, 
orbicular, very small, | in. long, deeply crenate, rather coriaceous. Scapes 
leafless, or with a small bract or solitary leaf, 2-3 in. long, silky or glabrous. 
Heads in. diam., globose. Calyx silky or pubescent, 4-angled, the angles 
thickened in fruit, not spinescent. Petals united at the base, green. Sta- 
mens 2 ; filaments short. Achenes 2 ; stigma dilated, fimbriate on one side.

Several European Rosacea have beeu introduced into New Zealand, of which some, as the 
Briar-rose, are said to be naturalized. 
Alchemilla ( Aphanes ) arvensis, Linn., a procumbent, much branched annual, with small 
cut leaves, and very minute green flowers, is sent by Mr. Travers, from Tarndale plain, 
alt. 4000 ft. ; though stated by Brown to be indigenous to Australia, I thiuk there can be no 
doubt of its beiug introduced there, and into New Zealand also. 
Slaphylorhodos Cotoneaster, Turczaninow, in Bull. Soc. Imp. Mosc. 1802, ii. 321, — a 
plant referred to Rosacea, but if correctly, certainly a very anomalous member, is stated 
by its author to be a native of New Zealand, sent by Sir Everard Home, II. N., to It. Brown 
(n. 563 and 579), at the sale of some of whose collections it was purchased. There is, how- 
ever, no such plant nor number in the original collection of Sir E. Home, preserved in the 
British Museum, nor any New Zealand plant at all agreeing with the characters of this. 
Order XXIV. SAXIFRAGES. 
Herbs, shrubs, or trees. Leaves opposite or alternate, simple or compound, 
stipulate or exstipulate. Flowers usually hermaphrodite and regular.- — Calyx 
free or adnate to the ovary, lobes 4 or 5, valvate or imbricate. Petals 4 or 
5, valvate or imbricate, usually small and coriaceous. Disk perigynous or epi- 
gynous. Stamens usually as many or twice as many as the petals, in 
Donatia fewer. Ovary 2-5-celled ; styles 2-5, stigmas usually capitate ; 
ovules numerous, on axile or rarely parietal placentas. Fruit generally a cap- 
sule with many seeds, almost a berry in Carpodetus , unknown in Donatia. 
Seeds usually small; albumen copious ; embryo terete (large, with scanty 
albumen, in Ixerba). 
A large Order, containing very many different forms, so that it is impossible to define it 
tersely. The immense herbaceous tribe of Saxifrages proper is represented by Doualia 
alone iu New Zealand.
