CXXV. BEUNONIACE^. 609 



We have indicated the affinity of Goodeniaoece with Brunoniaeecs and Stylidiecs (see these families). 

 It is also allied to LobeliacecB in its epigynous stameins, isostemonoua corolla, seativation, many-celled 

 ovary, anatropous ovules, axile embryo and fleshy albumen. But Lobeliaceee differs in the stigma having 

 a ring of hairs, and not being sheathed by an indusium. 



Goodeniacece are almost exclusively Australian, and especially extratropical. The species of Scesvola 

 have migrated to the Moluccas and the Indian continent, and thence to the South of Africa [and the 

 Pacific Islands. SeUiera inhabits the coasts of Australia, New Zealand, Chili and Fuegia]. We know 

 little for certain respecting the properties of some Indian SccsvoltB. The leaves and berry of the Mokal 

 [S. Taccadd] yield a bitter juice supposed to remove cataract, and its young leaves are eaten as a vegetable. 

 The inhabitants of Amboina use the root to enable them to eat with safety poisonous crabs and fish. 

 The pith is used in cases of exhaustion [and extensively in the construction of ornaments, models, &c.]. 

 The leaves of S. Bela-modogam [probably identical with S. Taccadd], a native of Malabar, are applied as a 

 poultice on inflammatory tumours, and a decoction from them is diuretic. Goodenia, Euthahs, and Lesche- 

 naaltia are cultivated in European hothouses as ornamental plants. 



CXXV. BRUNONIACEJ^} 

 (Brunoniace^, E. Br.) 



Flowers fascicled, fascicles aggregated into an involucrate capitidum. Corolla 

 hypogynous, monopetalous, isostemonous, aestivation valvate. Stamens hypogynous ; 

 ANTHERS syngenesious. Ovart free, 1-celled, 1-ovuled; stigma indusiate; ovule erect, 

 anatropous. Fruit a utricle. Embryo exalbuminous. 



Perennial nearly stemless herbs, resembling Scabious. Leaves radical, close-set, 

 spathulate, entire. Flowers 5 , sub-regular, eacb with 5 whorled bracteoles, agglo- 

 merated in fascicles united in an involucrate capitulum, and separated by bracts 

 like those of the involucre. Scapes many from the same root, simple, and termina- 

 ting in a single capitulum. Calyx-tube short ; limb divided into 5 subulate plumose 

 segments. Corolla hypogynous, monop«talous, infundibuliform, persistent, tube 

 splitting after flowering, limb 5-fid, lobes spathulate, the 2 upper deeply divided. 

 Stamens 5, inserted on the neck of the ovary, included ; filaments flat, articulate, 

 free ; anthers linear, 2-ceUed, introrse, coherent in a tube around the style. Ovary 

 free, shortly stipitate, 1-celled ; style terminal, simple, exserted, hairy above ; stigma 

 obconic, truncate, fleshy, in a sheath bifid at the tip ; ovule solitary, basilar, ana- 

 tropous. Fruit an indehiscent utricle, enclosed in the enlarged and hardened calyx, 

 and crowned by the plumose segments of the calyx-limb. Seed erect. Embryo 

 straight, exalbuminous ; radicle irderior. 



ONLY GENUS. 

 * Brunonia. 



Srunoniacees approach Qoodeniaoeee by the indusiate stigma ; Campanulacecs and Lobeliaceee by its 

 inflorescence, isostemonism, aestivation of the corolla, free filaments, anatropous ovule and hairy style ; it 

 differs in its hypogynism, its solitary erect ovule, the absence of albumen, and especially in the indusiate 

 stigma. The same analogies exist between Srunoniacece and Compositts, and in addition, in both families 

 the ovule is solitary, erect and exalbuminous, and the calyx expands into a pappus ; the diagnosis, in fact,
