disk, has thi-ee bioviilate cells, and the fruit is (before matu- 

 rity) membranous and glandular. The seeds bear a small aril. 

 The leaves of Loxodiscus are inii^aripinnate. Ungnadia^ consisting 

 of small Texan trees, is also closely allied to Erithrophjm., 



Magcmia pidesceiis.

having its perianth, the petals lined at the top of the claw 

 with an appendage lobate and cut in tufts, to the number of foui- 

 or five ; and the three ovary cells each containing two ascendent 



ovules. But the fruit is a thick 

 coriaceous capsule, depressed at 

 the apex and apiculate, loculicidal. 

 The exalbuminous seeds contain 

 a fleshy embryo resembling that 

 of JEsadns. Like Erithrophym^ 

 JJnynadia has early polygamous 

 flowers, developed before the im- 

 paripinuate leaves. 



The Magonim (fig. 399-403) 

 constitute a small distinct and 

 anomalous group in this series, 

 by their nmltiovulate ovary cells 

 and winged seeds. They have 

 very nearly the floAvers of Erithro- 

 physa and Cossignia, with five unequal petals destitvite of appen- 

 dages, a large unilateral disk, lined and cut in a lobate ridge. The 

 three ovary cells each contain in the internal angle two vertical series 

 of ovules, and the voluminous, loculicidal fruit, opens in tln-ee large
