298 NATURAL HISTORY OF PLANTS. 



restored the Cassipourece to the Rhizoplwreœ ; ' according to him as 

 also to Lindley, it was only the genus Crossostylis of Forster that 

 ought to be transferred to another family, that of Myrtacece. After 

 many labours, particularly by Blume, Arnott, Kokthals, and A. 

 Gray, the Cassipourece, considered as a tribe of the Rhizophoraceœ 

 were, in 1858, the subject of a special memoir by Mr. Bentham, 2 

 who reunited iu this group the nine genera Carallia, Pellacalyx, Ma- 

 plopetalum, Gynotroches, Crossostylis, Anstrutheria, Blepharistemma, 

 Dactylopetalum, and Gassipourea. The Rhizophoreœ, on the other 

 hand, after the labours of Wight and Arnott, 3 comprised the four 

 genera Rhizophora, Bruguiera, Oeriops, and Kandelia. In 1862 we* 

 recognized that the genus Macarisia of Dupetit-Thouars, referred 

 to various families, in particular to the Rhamnacece, to the Meliaceœ, 

 to the Linaceœ, 5 was allied to Gassipourea ; that Anisophyllea 

 presented closer floral analogies to Carallia ; that Anstrutheria 

 belonged to the old genus Weihea of Spkengkl, and that certain 

 species of Crossostylis G did not differ generically from Haplopetalum 

 of A. Gray. At present we do not think it possible to refer Plœsi- 

 a ni 'lia of J. D. Hooker to the genus Pellacalyx as an apetalous type, 

 and we restore to Carallia its primitive name of Barraldeia, which 

 dates from 1806. Consequently, we provisionally retain iu this 

 family only fourteen genera, distributed in four scries in the 

 following manner : 



I. Rhizophoreœ. — Receptacle concave and ovary partly or entirely 

 inferior. Style simple. Seed exalbuminous, with macropod embryo, 

 germinating in the fruit and on the tree. — Trees of the sea coast ; 

 leaves opposite, entire, with interpetiolate stipules. — 4 genera. 



II. BARRALDiEiE. — Receptacle concave and ovary partly or entirely 

 inferior. Style simple. Seed furnished with albumen surrounding 

 the embryo which does not germinate in the fruit. — Trees and 

 shrubs ; leaves opposite, generally entire, with interpetiolate stipules. 

 — 4 genera. 



III. Macarisie.e. 7 — Receptacle concave or convex and ovary free 

 sessile or shortly stipitate. Seed albuminous arillate or winged. —
