402 NATURAL HISTORY OF PLANTS. 



axillary compound- cymose ; pedicels slender, ebracteolate ; the 

 fructiferous bare. (Canary Isles, Madeira.^) 



25. Opercularia G^rtn.^ — Flowers hermaphrodite or polyga- 

 mous, spuriously capitate; calyx 3-6-merous, persistent. Corolla 

 rather long tubular ; lobes of patent limb 3-6, valvate; throat glabrous. 

 Stamens same in number (more rarely 1-3), inserted at bottom of 

 tube; filaments slender exserted; anthers introrse, dorsifixed above 

 base. Germen inferior (adnate within concave receptacle) ; style 

 branches 1, or oftener 2, generally free from base, exserted, papillose- 

 hirsute. Ovule 1, suberect anatropous; micropyle extr or sely inferior. 

 Fruit compound {'' syncarpous "), generally augmented by persistent 

 calyx, consisting of oo , or more rarely 2, 3 {Fornax ^) capsules ; each 

 finally 2-valvate ; exterior valves connate in persistent cupule ; interior 

 in a spurious obconical deciduous operculum. Seeds oblong, smooth 

 or rugose, piano- or concavo-convex ; coat thin ; cotyledons of richly 

 and densely albuminous embryo superior foliaceous. — Undershrubs or 

 herbs, rarely twining, glabrous or pilose (generally foetid); leaves 

 opposite; stipules connate with leaves in an interpetiolar sheath; 

 flowers* in spurious terminal or lateral capitules,^ involucrate and 

 involucellate, stipitate or subsessile, sometimes ramose, many-flowered, 

 or more rarely 2, 3-flowered (Fornax), (Australia.^) 



26. Eleuthranthes F. Muell.^ — Flowers of Opercularia, 4, 5- 

 merous, crowded, spuriously capitate ; germens (receptacles) free. 

 Lobes of calyx 4, 5, linear, equal or unequal, hirsute, subspathulate, 

 persistent. Corolla ^ thin funnel-shaped ; lobes 4, 5, valvate, ciHate, 

 revolute. Stamens inserted at base of corolla ; filaments long very 

 thin; anthers ovately acute introrse, versatile. Germen inferior, 1- 

 celled, 1-ovulate (of Opercularia); style branches 2, slender, exserted
