LINAGES. 47 



which, five shorter are superposed to the petals. Their filaments 

 are united below into a short tube, with five alternipetalous angles 

 sometimes thickened, as in the Flaxes, into elongate glands ; after- 

 wards they separate, and each bears above, abilocular, introrse anther, 

 dehiscing by two longitudinal clefts. The ovary is formed of five 

 alternipetalous cells, more rarely of four or three, surmounted by a 

 like number of style branches, capitate stigmatiferous at the apex. 

 In the internal angle of each cell are seen two descendent ovules, 

 generally collateral with exterior micropyle surmounted usually by 

 a thick obturator. The fruit is a drupe enclosing from three to five 

 mono- or dispermous stones. The seeds are generally compressed, 

 and contain under their coats a fleshy albumen, surrounding a 

 straight or arched embryo, with short superior radicle. Hugonia 

 consists of shrubs, often climbing, from all tropical regions, with 

 alternate simple penninerved leaves accompanied by entire or slashed 

 stipules. The flowers are generally in terminal ramified racemes com- 

 posed of ebracteate cymes. As a rule also the lower divisions of the 

 inflorescence, one or two in number, are transformed into a thick hook 

 recurved below and rolled spirally. In certain species of Hugonia^ prin- 

 cipally natives of tropical Africa, the flowers are united in the axils 

 of the leaves into very short racemes or spikes, simple or ramified. 

 It is so in Roucheria^ recently ascribed ^ to the genus Hugonia^ and 

 of which three species are known, two from tropical America, the 

 other from tropical Asia. The fiowers are accompanied by unequal 

 bracts of variable number, analogous to the sepals but smaller. 



In some Hugonias fi-om New Caledonia, recently described under 

 the name of Penicillanthemum,^ the stems are generally not climbing 

 as in Boucheria, the sepals are obtuse and the inflorescence destitute 

 of hooks at the base. The same characters are found in Sarcotheca 

 macrophylla,^ a shrub from the Indian Archipelago which ought, it
