Has. Middle Island. Nelson, Bidwill. 
This curious little species is much smaller than the usual state of A. Sanguisorbe, and has denser foliage, less 
silky, with short coriaceous rounded leaflets ; all variable characters, however. The unarmed calyx, which in fruit 
presents only thickened angles instead of spines, at once distinguishes it from 4. Sanguisorbe, or the following. It 
is nearly allied to the Falkland Island 4. lucida, Vahl. 
3. Aceena microphylla, Hook. fil.; pusilla, decumbens, glabrata, ramosa, ramis ascendentibus, petiolis 
pilosis, foliolis minimis 4—6-jugis rotundatis inciso-serratis, scapis erectis pilosis, capitulis magnis globosis, 
calyce 4-gono angulis incrassatis fructifero in aristas elongatas simplices productis, corolla gamopetala, 
staminibus stylisque 2, stigmatibus subclavatis fimbriatis. 
Has. Northern Island. Tongariro, Bidwill, Colenso. 
A very small and glabrous species; the leaflets not + inch long. Capitula very large for the size of the plant, 
upwards of an inch across, including the spines, which are not barbate, and distinguish it as a species. 
Another species, 4. ascendens, Vahl, common in Fuegia and the Falklands, has been found in Macquarrie 
Island, but hitherto not in New Zealand.

Calyx 5-lobus, extus 5-bracteolatus. Petala 5. Stamina 00, cum petalis inserta. Carpella sicca, in 
capitulum supra receptaculum siccum disposita; stylo caudato, post anthesin articulato, geniculato, v. 
barbato. Semen ascendens. 
A small genus of herbaceous plants, of which some species appear to be very widely diffused: it is distinguished 
from Potentilla by the long awns to the achenia. (Name from yevo, to yield a sweet flavour, from the aromatic smell 
of the root of a common European species.)

Has. Northern and Middle Islands. East coast and interior, Colenso. Nelson, Bidwill. Milford 
Sound, Zyall. (Cultivated in England.) 
All the parts are pilose, pubescent, or almost tomentose. Root woody, perennial, astringent. Stems rounded, 
2—3 feet high, dichotomously branching above. Radical leaves 4—6 inches long, interruptedly pinnate ; the terminal 
lobe very large, ovate or rounded, variously lobed and serrate, strongly veined, the others often alternately smaller, 
in two to six pairs, ovate or rounded, sessile, the lower gradually smaller: upper leaves incised, simple or pinnate, 
the lobes narrower and more deeply cut. Flowers yellow, 3 inch across, on very villous peduncles, which elongate in 
flower. Calyx pubescent ; lobes ovate, alternating with five bracteole. Petals rounded. Stamens very numerous. 
Heads of fruit oblong, rounded, + inch long, of very many compressed carpels, which are densely villous, with long 
stiff yellowish hairs, and terminate in stiff reflexed awns. wns + inch long, twisted suddenly above the middle, or 
hooked at the extremity.—I cannot see upon what grounds (judging from original specimens) the species quoted 
above (and some others) are to be separated from one another; and I am further inclined to consider all as varieties 
of G. urbanum. If species are to be founded upon every trifling difference in the size or proportion of the upper lobe
