AND STERCULIACES. 115 
and referring to Bombacee, the M. longiflora, forming the genus 
Quararibea, Aubl., as well as the species I had provisionally named 
in Spruce’s plants M. breviflora, but which I have above described 
under the name of Scleronema. On the other hand, Endlicher 
proves to have been correct in his suggestion that Lewarza, Llave, 
belongs to Myrodia. Specimens agreeing in every respect with 
that author's description of his L. funebris are in the Hookerian 
herbarium, from Oaxaca, Andrieux, n. 512, from Papantla, Lieb- 
mann, and from near Sonsonate in San Salvador, Sutton Hayes. 
The flowers are considerably larger than in AM. turbinata, from 
which it may be thus distinguished :—

In a paper of Dr. Planchon's in the 6th vol. of the * Flore des 
Serres’ (which we have been unable to procure, and which is 
therefore only known to us from the abstract in Walpers’ ‘ An- 
nales, iv. p. 325), the genus Dombeya is well characterized and 
divided into sections; and Xeropetalum, Delile, is correctly in- 
cluded. "We would also agree with him in considering the As- 
trapea viscosa, Bot. Map., and its allies as a section only of Dom- 
beya, in which the staminal tube exceeds the ovary; but, in so 
doing, it does not appear possible to exclude Hilsenbergia, Boj., 
and Astrapea, Lindl., which only differ in the staminal tube being 
still longer. Nor can we reject Assonia, Cav., which only differs 
slightly in the bracts from the smaller-flowered, short-columned 
species. Thus constituted, Dombeya forms a well-marked and 
natural genus of about 24 species, only separated, however, from 
Ruizia and Astiria by the sterile stamens or lobes of the column. 
Trocuetia, DC. 
This genus, extended to its proper limits, becomes a very natu- 
ral one, differing from Dombeya in its inflorescence and the shape 
of its flowers, in the more coriaceous calyx, and more numerous 
ovules in each cell of the ovary; from Pentapetes in its arborescent 
habit, in the calyx, and in the style more divided at the top ; from 
Methania, into which some species have been hitherto placed, it is 
still more distinct in habit and calyx, and in the anthers always 2, 
3 or 4 between each two sterile stamens, instead of one only as in 
Melhania. The species we have seen are T. grandiflora, Lindl.,
