 CONTRIBUTIONS TO THE BOTANICAL REGISTER. 689

Obs. Aerides paniculatum (Bol. Beg. v. 3, /. 220) generis pristini species impar nimis huic {monente D. Brown) apte satis associari potest. Parasitica ambce.

Van da BoxburgMi, ovariis contortis, petalis oblongo- ovatis undatis, foliis oblique tridentatis. Brown MSS.

The generic character now given has been formed by Mr. Brown so as to include Aerides paniculatum^ pub- lished provisionally by that generic name in our third volume (fol. 220) ; but now it will be seen that the species is not a very close congener of the one before us. The Cymbideum tessellatum of Roxburgh is not included in the present genus.

Mr. Brown had some scruple in not ranging the group under Angr^ecum of M. Du Petit-Thouars (of which a spe- cies is given in ' Voy. de Bory de St. Vincent/ 1359, tab. 19), not being able, from want of sufficient detail in the description of the structure of the parts of that genus, to decide satisfactorily whether he ought to do so or not ; and has at last been determined principally by the label in Angr^ecum being undivided, and probably membranous, while in Van da it is three-lobed and fleshy. He expects that several species of Swartz's genus Limodorum will be found to rank under the present.

Bot. Beg. 506 (1820).
