2. Aptandra tubicina, Bth. MSS. — Heisteria tubicina, Pop. Nov. 

 Gen. hi. 35. tab. 241 j — foliis ellipticis, apice repente lineari- 

 attenuatis, utrinque glabris, subtus ferrugineo-punctulatis, 

 rachi nervisque anastomosantibus laevibus et rubellis, venis 

 valde reticulatis ; paniculis axillaribus, petiolo 4-plo longiori- 

 bus, folio 7-plo brevioribus, pedicellis in fructu elongatis et 

 incrassatis, in flore capillaribus; drupa globosa, calyce aucto 

 laxe campanulato semi-inclusa. — Prope Panure, Ptio Uaupes,

This is described as a short tree with lax branches ; the axils 

 are about \\ inch apart; the leaves are 5| inches long and 

 2 inches wide, upon a petiole 3 lines in length. The inflores- 

 cence is about -J inch long ; the pedicels, which are capillary in 

 flower, become thickened in fruit, especially towards their sum- 

 mit, and are upwards of an inch in length ; the antheriferous 

 tube, which I have represented in the drawing, exactly resembles 

 that of the preceding species. The fruit is described in a pre- 

 ceding page.

4. Aptandra liriosmoides, Spruce MSS., n. sp. ; — foliis oblongis 

 vel lanceolato-oblongis, imo obtusis, apice subattenuatis, ob-
