"We are unable to determine the number of leaflets, they 

 having become detached from the common petiole. It is allied 

 to C. ccsciilifolia (= Bonibax ccsculifolium H. B. K. {Eriodcudron 

 DC.)) and C. tomeniosa. The former differs by its leaflets being 

 serrated at the margins ; in the latter the leaflets are also ser- 

 rated, and the staminal column is much shorter, and cor- 

 respondingly the free filaments are longer. Also allied to C. 

 Burtlicllii K. Schum., from Brazil, but this plant has a more 

 cylindrical calyx. There is a plant in the Kew Herbarium, col- 

 lected by Bernoulli and Cario in Guatemala, No. 3128, which is 

 very closely allied, but the lobes of the calyx are slightly 

 mucronate." 



"We have two sheets in the British Museum Herbarium from 

 Herb. Pavon, labelled ' Bombax erianthos de Mexico. ' These 

 seem to agree ver}' nearly with the description based upon im- 

 perfect material of Bombax (vsciilifoliui'n (H. B. K. Nov. Gen. v. 

 298). The leaflets are not, however, smooth below, but slightly 

 ferruginous tomentose on the veins and at the base. The petals 

 are broadly linear and ferruginous hirsute externally, and about
