NATURAL HISTORY OF PLANTS. 



Limonia (Triphasia) 

 trifoliala. 



cells of which contain one or two seeds. These have under their 

 coats a fleshy embryo, with superior exalbuminous radicle. Limonia 

 consists of fragrant shrubs of tropical Asia, the organs of which are 

 covered with pellucid 1 glandular points, prominent or depressed. 

 The twigs are often transformed into spines. The alternate exsti- 

 pulate leaves are trifoliolate or imparipinnate. 



We have attached as a section to the genus Limonia, Gli/cosmis, 2 

 only essentially differing from it by one character : the ovary, gene- 

 rally with uniovulate cells, is not articulated, but continuous with 

 the base of the style. 



L. trifoliata* (fig. 454), a small thorny Chinese shrub, has also 

 been generically distinguished under the name of 

 Triphasia f that also we can only preserve as a sec- 

 tion. Thus limited, the genus contains six or seven 

 species. 5 



Beside Limonia are placed a certain number of 

 other very nearly allied genera, of which several 

 have been perhaps uselessly detached from it. These 

 are : Murraya, whose pentamerous flowers have a 

 quinquefid or quinquepartite calyx, ten stamens 

 with linear subulate filaments, ovary cells one- or 

 tw.o-ovulate, and whose unarmed branches bear 

 pinnate leaves and flowers disposed in terminal cymes ; Micromelum, 

 which, with the same leaves and inflorescence, have pentamerous 

 flowers, a five-lobed or entire calyx, petals valvate or nearly so, ten 

 stamens, two superposed ovules in each cell, and an embryo remark- 

 able for its contortuplicate cotyledons ; Clausena, having also pin- 

 nate leaves, and whose flowers, disposed in simple or compound 

 ramified racemes, are 3-5-merous, with a lobed or partite calyx, 

 petals imbricated or subvalvate, diplostemonous androceum, staminal
