08 NATURAL HISTORY OF PLANTS. 



All are formed of a filament and a contimious anther, dehiscing by 

 an apical pore situated quite at the top of the apex elongated into a 

 rostrum. There are four cellules to the anther all

 is free, formed of an ovary with two cells, one 

 anterior the other posterior, siu-mounted by a 

 slender style with truncate stigmatiferous apex. 

 In the inner angle of each cell is a placenta sup- 

 porting a descendent anatropous ovule with 

 exterior and superior micropyle.^ The fruit is a 

 Fi<'.io3.G)-nœceum(a).bi-locular capsulc, comprcssed, loculicidal, then 

 septicidal. The seeds contain under theii- coats a 

 fleshy albumen surrounding a small axile embryo with superior 

 radicle. The only Flutyihcca known is a delicate shrub, a native 

 of Australia, as are all the species of this family. Its leaves are 

 verticillate ^ and linear ; the flowers * are axillary solitary and 

 pedunculate. 



The true Trcmandrm^ of which two species '' are known, are but 

 slightly distinct from Platijtheca ; their stamens, the anthers of 

 which are said to be articulate at the summit of a tenuous filament, 

 with only two cells, are separated from each other by five 

 oppositipetalous glands of a disk within which are inserted the 

 stamens alternate to the sepals. The seed is provided on a level 

 with the chalaza with a fleshy appendage in the shape of a curved 

 horn spirally rolled,^ and the ovary cells are generally biovulate. 

 — They are shrubs covered with stellate haii's, with opposite dentate 

 mcmbranoTis leaves.

 merons flowers.^ The androceumis diplostemonous; but the stamens,
