NATURAL HISTORY OF PLANTS. 



disk, has three biovulate cells, and the fruit is (before matu- 

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

 The leaves of Loxodiscus are imparipinnate. Ungnadia, consisting 

 of small Texan trees, is also closely allied to Erithrophysa, 



Magonia pubescens.

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

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

 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 JEsculus. Like Erithrophysa^ . 

 Ungnadia has early polygamous 

 flowers, developed before the im- 

 paripinnate leaves. 



The Magonias (flg. 399-403) 

 constitute a small distinct and 

 anomalous group in this series, 

 by their multiovulate ovary cells 

 and winged seeds. They have 

 very nearly the flowers of Erithro- 

 physa and Cossignia^ with five unequal petals destitute 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 three large
