CXXV. BKUNONIACE^]. 509 



We have indicated the affinity of Goodeniacete with Brunoniacecc and Stylidieee (see these families). 

 It is also allied to Lobeliacece in its epigynous stamens, isostemonous corolla, aestivation, many-celled 

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

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



Goodeniacea are almost exclusively Australian, and especially extratropical. The species of Scavola 

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

 Pacific Islands. Selliera inhabits the coasts of Australia, New Zealand, Chili and Fuegial. We know 

 little for certain respecting the properties of some Indian Sccevolce. 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. Taccada], a native of Malabar, are applied as a 

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

 nauttia are cultivated in European hothouses as ornamental plants. 



CXXV. BRUNONIACEJE. 1 



(BRUNONIACE^E, R. Br.) 



FLOWERS fascicled, fascicles aggregated into an involucrate capitulum. COROLLA 

 hypogynous, monopetalous, isostemonous, cestivation valvate. STAMENS hypogynous ; 

 ANTHERS syngenesious. OVARY free, l-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 $ , sub-regular, each 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 stibulate plumose 

 segments. COROLLA hypogynous, monopetalous, 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-celled, introrse, coherent in a tube around the style. OVARY 

 free, shortly stipitate, l-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 inferior. 



ONLY GENUS. 

 * Brunonia. 



Brunoniacece approach Goodeniacece by the indusiate stigma ; Campantdacea; and Lobeliaccte 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 JSrunoniaceee and Composites, and in addition, in both families 

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