 The radicle is close to the hilum.

GUTTIFEILE. 



Benth. et Hook. Gen. PI. i. 167. 



Fruit and Seed. The ovary of the Guttiferae varies from 

 two to many cells, except in Calophyllum and Kayea, where 

 it is one-celled and one-ovuled. There is only one ovule in each 

 cell of Tovomita and in the tribe Garciniese, otherwise almost 

 without exception the ovules vary from two to many in each 

 cell, and are erect and anatropous, attached to a central placenta 

 or arising from the base of the cavity, with the micropvle 

 inferior. The fruit is fleshy, leathery, or pulpy, and rarely 

 dehisces at maturity except in the tribe Clusieae, where it 

 splits into valves at the septa. The seeds are large, frequently 

 solitary in each cell, sometimes numerous amongst the species 

 of Clusia, and often enveloped at the base by a lobed or corru- 

 gated aril or arillode. The testa is membranous and leathery, 

 rarely spongy as in some species of Calophyllum ; in the Man- 

 gosteen (Garcinia Mangostana) it is covered with a thick pulpy 

 aril, forming the edible part. Endosperm is wanting. 



The embryo is large, filling the seed, to which it conforms : 

 it presents a remarkable and abnormal case, inasmuch as it 

 often consists mainly of a swollen and fleshy radicle with 

 small and scale-like inconspicuous cotyledons at its apex as in 

 the tribe Clusiese, while they are said to be absent in the
