THE TASMANIAN FLOBA. 



4. DONATIA. 



Calyx-lobes 4 or 5. Petals of the same mimber, inserted round a broad flat 

 disk. Stamens 2 or 3, inserted on or within the disk. Ovary inferior, 2 or 

 3-celled, with several ovules in each. Styles short and thick, united at the base. 



A genus of small tufted plants, containing but few species. The characters 

 are tolerably distinct from any particular order, approaching in many details 

 most nearly the Saxifrages, but the fruit is that of Stylidiums ; and although 

 the stamens do not combine with the style, they are inserted close to its base. 



D. NOVJi-ZBALANDiBa!, Hook. A small densely-tufted perennial, with an almost 

 moss-like appearance. Leaves linear, about 2 lines long, very crowded along the 

 stems. Flowers solitary, sessile, terminal. Calyx-lobes 5, linear. Petals 5, 

 white, ovate, aboat 2 lines long. Stamens 2, inserted near the centre of the disk, 

 close to the base of the style, and almost cohering with it. Ovules about 12 in 

 each cell, in a dense tuft, pendulous from the top. Fruit a capsule, about 2 lines 

 long, dehiscing transversely. 



Summit of many mountains ; Mt. La Perouse, Mt. Olympua, &c. ; also an 

 alpine New Zealand plant. Fl. Dec.-Feb. 



Ordek XLII. GOoDENOVIACE^. 



Floral-tube adnate to the ovary, in rare instances free. Sepals 5, sometimes 

 reduced or obsolete. Corolla irregular, but sometimes appearing almost regular. 

 The free portion of the petals usually lanceolate, but in most instances developing 

 marginal expansions or wings. Stamens 5, inserted at the base of the corolla. 

 Anthers usually free, but in JDampiera and Biunonia united in a sheath round 

 the style. Ovary more or less combined with the tube inmost Tasmanian plants, 

 imperfectly 2-celled in most genera, 1-celled in Dampiera and Brunonia. Ovules 

 1-2 or many. Style simple. Stigma cup-shaped or in a linear, more or less 

 curved, groove, protected by hirsute lips till mature. Fruit drupaceous or 

 capsular. 



The order is almost exclusively Australian, few species, of but 2 genera, 

 occurring beyond that distribution. The stamens as a rule attain maturity 

 almost before the flower opens, and the stigma does not advance to the mouth of 

 the indusium till long after. 



Flowers yellow.

1. VELLEYA. 

 Calyx free, of 3 or 5, usually free, sepals. Corolla united with the ovary at 

 the base. Stamens free. Ovary imperfectly 2-celled, with many ovules in each. 

 Indusium usually deeply curved. Seeds flat, with a moi'e or leas winged margin.
