with, accrescent and scarious appendages. But these appendages are de- 

 pendent from the calyx, and not from the corolla. Astronium is formed 

 of trees from tropical America with imparipinnate leaves. Parishia, 

 a tree from Malacca, has also imparipinnate leaves, and round the 

 fruit a large indusium formed by the accrescent calyx, hut its wings 

 are only four in number, like the petals and stamens, and the pre- 

 floration of the sepals valvate and not imbricate. Loxostylis (fig. 

 308, 309), a small tree from the Cape of Good Hope, also represents 

 an allied genus in which the sepals are equally persistent and accres- 

 cent round the fruit in a foliaceous indusium, but its petals are slightly 

 unequal, and especially its five stamens altematiag with an equal 

 number of bilobate glands. The ovary, with one fertile cell, is sur- 

 mounted by three styles inserted more or less low towards the middle 

 of one of its edges. 



In Lossopterygium, formed of American trees with imparipinnate 

 leaves, imbricate corolla and isostemonous androoeum, the fruit is still 

 accompanied by an aliform dilatation, but this expansion is dependent 

 from the pericarp and not from the calyx, and recalls the lateral 

 samara of Secnridaca and certain leguminous plants. Botryceras, 

 a shrub irom the Cape, also has isostemonous flowers and a com- 

 pressed fruit, with a membraneous, winged epicarp, garnished uni- 

 laterally by the persistent style ; but it is easily distinguished by 

 simple leaves and the dilated and compressed axes of its female in- 

 florescence, which finish by making a sort of pectinate fasciation. 

 In Smodingium^ formed of shrubs from the same country and Mexico, 

 they are also isostemonous, with imbricate corolla and samaroid fruit ; 

 but in these it is the edges of the pericarp that are dilated in wings 

 on the whole of their periphery ; the leaves are trifoliolate. Faguetia 

 falcata, a tree- from Madagascar, owes its specific name to the form 

 of its fruit, also samaroid, elongated, flattened, attenuated at the 

 two extremities, unilocular in its upper portion, but owing this ap- 

 pearance to the follicular dilatation of its inferior part. Its declin- 

 ate flowers are usually tetramerous, isostemonous, with imbricate 

 corolla, and its leaves are compound-pinnate.^ 



1 There is, it seems, great resemWamce te- form'ed by the dilated pedicel, surrounded by a 



tween this genus and /MKama, a Mexican tree, swollen pericarp, unilocular (?), mouospermous 



very imperfectly known, whose imparipinnate (often monstrous or deformed?). The flowers are 



leaves are analogous to those of most TereUn- dioecious, and the male have, it is said, four to 



thaceee, and whose firuit has also the form of an eight leaves in the perianth, with an equal 



elongated samara. But its flattened portion is number of fertile stamens.
