THE TASMANIAN FLORA. 10&' 



Fraiting-calyx red, and, in all I have examined, only about half-enclosing the 

 capsule, which is somewhat fleshy. 



Found on the summit of many mountains. It occurs in New Zealand. Fl. 

 Dec-Jan. 



Order XLY.—EP ACRID ACE^. 



Calyx of 5, rarely 4, distinct sepals. Corolla of a similar number of petals, 

 more or less united, regular. Stamens equal in number to the lobes of the corolla, 

 not always perfect in flowers developing perfect ovules, inserted below the ovary 

 or on the corolla-tube. Anthers 1-celled, opening by a single longitudinal slit, 

 free, but in one genus often cohering in a ring round the style {Sprengelia). A 

 disk usually developed between the stamens and pistil, sometimes of 5 free scales 

 or the scales united, but not always reliable in form even in the same species. 

 Ovary usually 5-celled, but varying from 1-10, either 1 pendulous ovule in 

 each cell or many arising from an axile placenta. Style simple, and in all those 

 with solitary ovules in the cells a simple continuation from the ovary, in the 

 many ovuled species the style is sunk in a central depression. Stigma simple or 

 slightly lobed. Fruit a more or less berry-like drupe in the solitary-ovuled, and 

 capsular in the many -ovuled, tribe. 



The genus, though very large, is almost confined to Australian, New Zealand, 

 and corresponding Pacific and Antarctic distribution. It is closely allied to 

 Ericaceas, from which it is separated, however, by the unilocular development 

 of the anthers. 



The order is naturally divided into 2 tribes. The first, Styphelieee, 

 containing a very large number of species, has not developed sufficiently 

 clear dividing-lines amongst its varied forms to render generic divisions 

 easy without having recourse to details of small genetic value. It 

 would, periiaps, be more exact to follow von Mueller, and treat the 

 large mass as members of one genus . 



Tribe Sl.ypheliecB. Ovary 1-10 celled, containing 1 ovule in each cell. Style 

 enlarging at base, or abruptly ascending from ovary.
