as cells or placentas, tlic valves rarely splitting septicidally. Seeds several, 

 mth a reticulate testa, sometimes produced beyond the nucleus into a loose 

 wing; embryo cylindrical or sometimes minute in a fleshy albumen. — Herbs. 

 Leaves usually ciliate or covered with glandular hairs. Flowers solitary or in 

 one-sided racemes, either simple or forming a branching cyme. 



A small Order, found in nearly all parts of the world, the principal genus closely allied to 

 the herbaceous Saxlfragece^ dilFeriug chiefly in the insertion of the petals and stamens, being 

 more generally hypogynous ; the whole group is easily recognized by the glandular leaves, 

 iuvohitc in vernation. Of the two Australian genera, the principal one constitutes nearly the 

 whole Order and ranges over the general area, the other is eudcniic aud very anomalous.

 2 to 5, usually 3, parietal placentas ; styles as many as placentas, simple or va- 

 riously branclicd. Capsule opening in as many valves as placentas, with the 

 placentas in their centre.— Herbs. Leaves usually involute in vernation, the 

 lamina more or less covered on the upper side with glandular hairs or ciha 

 and bordered with longer ones, usually irritable and closing over insects or 

 other objects resting on them, the imder side and petioles without glandular 

 tairs. Stipules when present searious and usually lobed or jagged. Flowers 

 solitary or in one-sided racemes or forked cymes, ou radical scapes or tenmaal
