Descriptions of Malayan Plants, 



slightest attention to the terms of the description ought to 

 have prevented. In the first volume of the same work, 

 the Arbor vernicis is made a species of Terminalia, under 

 the specific appellation of T. Vernix, and the supposition 

 has not been rejected by later authors. It is needless to 

 add, that it has not the least relation to Terminalia.

MILLINGTONIA.* Roxb. 



Calyx 5 — phyllus, foliolis duobus exterioribus minoribus. 

 Corolla 5 — petala, petalis duobus minoribus squamiformibus. 

 Stamina quinque, quorum tria sterilia difFormia basi peta- 

 lorum majorum inserta ; duo fertiHa basi minorum adnata, 

 filamentis apice scyphum gerentibus cui antherae bilobae 

 insident. Ovarium nectario annulari cinctum, biloculare, 

 loculis disporis. Drupa nuce plerumque monospora. Em- 

 bryo erectus, curvatus, albumine nullo aut parco. 



Obs. — It will be perceived that I have made a considerable 

 and material alteration in the terms of the generic descrip- 

 tion from that given by Roxburgh, Fl : Ind : I. p. 102, 

 which I conceive to be necessary towards explaining the 

 true relations of the various parts of the flower, and thereby 



* The explanation of Mr. Jack and of Dr. Arnott does not appear to 

 me to apply to Millingtonia simplicifolia, in which, from observations 

 made in Upper Assam in 1837, there would appear to be a composition 

 of two of the three acknowledged petals. This, though it may appear | 

 to increase the complexity of the flower, will be found perhaps to { 

 simplify it essentially. It seems to me, moreover, not improbable that 

 in this genus, as it now stands, there are two modifications of structure 

 of the flower, which may hereafter lead to the formation of another 

 genus. — W. G.
