Guianensi.— Foliola 2-3 poll. longa, pleraque vix semipollicem lata, 
maxima rarius 4 poll. longa et fere pollicem lata. Panicule pube 
minuta cinerascentes. Pedicelli iis S. Guianensis longiores et tenu-

In Planchon's enumeration of Simarubeæ, he appears to have over- 
looked the Simaba Bahiensis, Moric. Pl. Nouv. Amer. p. 11, t. 9, which 
is Blanchet’s no. 3143, and perhaps also Gardner's n. 2514 from 
Piauhy. In the generic character of Simaba in the same paper, the 
* squama staminum longa sæpe bifida" applies only to the larger- 
flowered. species, for it is very short in S. Guianensis, Orinocensis, fetida, 
and angustifolia. e 
The Ochnacee, lately worked up with great care by Dr. Planchon — 
(Lond. Journ. Bot. vol. v. and vi.), are nevertheless excessively difficult to 
determine from descriptions. Of the four Gomphiæ in the present — 
collection, two from Santarem and one frem Barra do Rio Negro, all 
in single specimens or nearly so, appear different from any I possess, 
yet I am unable to satisfy myself that they are really unpublished ; the 
fourth, from the Rio Tapajoz near Santarem, is however more evi- 
dently distinct, and has been more generally distributed. I therefore 
here describe it :— . sa
