Has. Middle Island. Var. a. Dusky Bay, Forster, Menzies. Var. 8. Port Preservation, Lyall. 
A small branching shrub, with the young branches, leaves below, peduncles, their bracts, and involucre densely 
covered with a thick, loosely appressed coat of white wool, which turns yellowish in drying, and almost hides the 
nerves of the leaf. Leaves crowded at the ends of the branches, spreading, very thick, coriaceous and rigid, 24-34 
inches long, sharp-pointed, narrow, linear-lanceolate in var. a, broader and obovate-lanceolate in var. 8, which also 
bears leaves like var, a; margins cut into many short, blunt teeth. Peduncles axillary amongst the upper branches, 
shorter than the leaves, stout, erect, one-flowered, covered with closely imbricating, ovate, blunt bracts. Heads 1 
inch broad, nearly 2 inches in var. a, on account of the long ligule, which are, when spread out, nearly an inch 
long.—This beautiful plant I never knew perfectly till Dr. Lyall brought fine specimens from New Zealand. In the 
‘Flora Antarctica’ (vol. i. p. 87) I considered this to be the same as the following species, O. semidentata, and as 
belonging to the same genus with Chiliotrichum amelloides of Fuegia and the Falkland Islands (Flora Antarctica, 
vol. ii. p. 304 bis); the latter genus, however, I now retain, on account of the narrower receptacle and linear scales 
amongst the outer flowers of the disc. 
2. Olearia semidentata, Decaisne; fruticulus erectus, ramulis gracilibus, foliis subtus pedunculis 
bracteisque lana appressa dense vestitis, foliis lineari-oblongis lanceolatisve acutis remote serratis, pedun- 
culis gracilibus, bracteis paucis remotis, floribus radii ligula elongata, acheniis elongatis costatis. Decaisne, 
Icon. in Voy. Venus, nullis notis adjectis. 
Has. Chatham Island, Diefenbach. 
Apparently a smaller plant than O. operina, with more slender branches and peduncles, more appressed and 
floccose down. Leaves 14-24 inches long, more linear and oblong, less contracted into a petiole, and much less 
coriaceous than in O, operina, sharp but not acuminate, remotely toothed. Peduncles variable in length, with a few 
linear-oblong, very woolly bracts. Heads 1-14 inches broad.— The specimens figured in Voy. Venus are larger 
and have rather more lanceolate leaves than mine; they were gathered at Chatham Island, I believe. 
8. Olearia angustifolia, Hook. fil. ; ramis robustis, ramulis foliis subtus pedunculis involucrisque dense 
lanatis, foliis confertis anguste elongato-lanceolatis longe acuminatis creberrime crenulatis subtus nervosis 
crassis coriaceisque, pedunculis validis, bracteis superioribus foliaceis, acheniis sericeis costatis. 
Has. Southern Island, Dr. Lyall. 
Apparently a large shrub, with stout branches, and branchlets as thick as the little finger, covered, as are the 
leaves below, with a dense white tomentum.. Leaves 3-5 inches long, 3 inch broad, very thick and coriaceous, 
narrow, linear-lanceolate, tapering to a long sharp point, the margins very closely crenate, with small blunt teeth; 
under surface marked with prominent parallel veins. Peduncles of old flowers only seen, nearly as long as the 
leaves, axillary, stout, erect, covered loosely with large linear bracts below, which above become larger and quite 
like small leaves, an inch long. Scades of the old involucre linear-lanceolate; pappus rather short, brownish. Fruit 
deeply furrowed and ribbed, silky. 
$ b. BRACHYGLOSSA. Flowers in terminal and axillary panicles, with short rays or none. : 
4. Olearia Colensoi, Hook. fil.; ramulis robustis foliisque subtus dense tomentosis, folis obovatis 
petiolatis acutis irregulariter et argute subduplicato-eroso-serratis superne impresso-venosis, paniculis 5-7- 
cephalis, capitulis pedicellatis, bracteis late ovatis concavis sericeis, involueri squamis glabratis apices versus
