Until the fruit shall have been seen, it is impossihle to fix the genus of this fine specie*. 

 Itbs the foliage of the Indian section Cl^pearia of Piihecolohiiim, the flowers are more like 

 those of several American CaUiandras.

Calyx eitlier endosing the ovary, or adhering to it, or quite free, 5-, rarely 

 4-lobed, with the addition, in a' few genera of as many external accessary 

 lobes. Petals as many as true calyx-lobes, inserted on the calyx at the base 

 of the lobes, or in Stylobasinm hypogjaious. Stamens indefinite, rarely few, 

 inserted with the petals, free. Ovary of 1, 2 or more carpels, usually distinct 

 at the time of flowering, but sometimes combined even then into a single 2- 

 to o-celled ovary, which is then always Inferior or combined with the calyx; 

 ovules 1 or 2, rarely more in each carpel ; styles or sessile stigmas distinct. 

 rriiiting carpels either free or variously combined with each other or with the 

 calyx, indehiscent or rarely opening along the inner edge. Seeds without 

 albumen or rarely albuminous ; embrvo with large cotyledons and a short ra- 

 dicle.— Trees shrubs or herbs. Leaves alternate, simple or compound, almost 

 always with stipules. Flowers in axillary or terminal cymes or solitary, very 

 rarely in simple racemes. 



A numerous Order, widely spread over the globe, but more in tlie temperate and cooler 

 parts of the northern hemisphere than within the tropics or in the southern tje^nispliere. 

 Of the seven Australian genera, one extends over the tropics of the Nuw and the Old \> oUd, 

 four belong to the extratropical flora of the northern hemisphere, with a few tropical species, 

 fspeciaUy in mountain ranges, one, Amna, is also chieQy extratropical, but m the southern 

 »'emisphere, with very few species extending into the tropical mountains or northern tem- 

 perate regions of America; one only, Stylobasinm, is endemic m Australia. ^ 



Of the several tribes into which Rosacea are divided, a few only are represented i 

 Win, and those only hv one or two genera each, it is therefore useless eutenng nito any ue- 

 t^iiled exposition of thei'r characters.
