2. Pamphilia styracifolia, A. DC. loc. cit. 271 ; Delessert, Icon. 
Sel. V. 18. tab. 42. — Brasilia (Prov. Minas Geraes. Claussen, 
135 ; Gardner, 4994). — v. s. 
I have two specimens of the latter species, one collected by 
Claussen, the other by Gardner : in the latter the anther-cells 
are entirely void of pollen, and the filaments below them are 
united into a monadelphous tube ; in Claussen’s specimen the 
filaments are distinct, and free nearly to the base, as shown in 
Delessert’s excellent representation; the anthers are pollini- 
ferous. The ovary is ovuligerous, as in Gardner’s plant. It is 
therefore most probable that in P. aurea the union of the fila- 
ments for nearly their whole length, as described by Prof. DeCan- 
dolle, is a sexual, not a general character. 
5. POVEOLARIA. 
This genus was established by Ruiz and Pavon upon five 
Peruvian species : of these. Prof. A. DeCandolle rejects fom-, 
which he refers to Styrax {Strigilia), retaining only F. feri'u- 
ginea ; of the latter, an excellent figure is given in Delessert’s 
‘ leones Selectse,’ v. tab. 43, the detailed analysis of which, and 
the description in the ‘ Prodromus,’ constitute all the knowledge 
we have concerning it. As I have never seen a specimen, I 
cannot form a decided opinion of the validity of the genus. Like 
Pamphilia, it is distinguishable from Strigilia in its ovary having 
only a solitary erect ovule in each pseudo-cell ; but it differs again 
from Pamphilia in having, like Strigilia, 10 stamens. Its chief 
differential character, that of its monadelphous stamens, as I 
have suggested in Pamphilia, is probably only a sexual feature, 
and not more than a lax agglutination of the margins of the fila- 
ments : that of its free ovary is common to Strigilia and all the 
genera of the Styracinece. It resembles Pamphilia greatly in
