1. Byttneria lanceolata. Fl. Mexic. — Var. ? pedunculis 1-3-nis subunifloris. 

 Fructus cocci tuberculati, tuberculis confertis acutis 2-3 subulato-attenuatis csetera longe superantibus. 

 1 . Melochia parvifolia. H. B. K. 

 1. Riedleia serratcu Vent.? 



Our specimen is so imperfect that we cannot determine whether it belongs to Riedleia or Melochia : it 

 does not agree well with De Candolle's description of R. serrata, but that is the orJy Mexican species of 

 either genus hitherto noticed by Schlechtendal that at all approaches to it. 



Ord. XIV. TILIACEiE. Juss. 

 1. Corchorus siliquosus. Linn. — Schlecht. in Linn. 11. p. 376. 



1. Triumfetta dumetorum. Schlecht. in Linn. 11. p. 377 ? 



Our specimens agree well with the description there given, except " floribus versus apices in cymas axillares 

 iispositis," whereas they form an almost leafless thyrse or compound contracted raceme. 



2. T. paniculata. H. et A. — Triumfetta sp. Schlecht. in Linn. 6. p. 424, et 11. p. 376. 

 Capsulse setse glabrae tenues fructus longitudine. 



Ord. XV. EL^OCARPEiE. Juss. 

 1. Elseocarpus photinice/olius. H. et A. supra, p. 259. tab. LIII. 



As the majority of the specimens collected in the expedition were placed along with the Mexican plants, 

 we insert the species here, not doubting, however, but this took place through inadvertency. It may, how- 

 ever, have been cultivated in some garden in Mexico. 



Ord. XVI. TERNSTRCEMIACEiE. Mirb. 



1. Cochlospermum serratifolium. De Cand. — Schlecht. in Linn. 11. p. 251. 

 No leaves accompany this specimen. We have the same from the island of Antigua.
