MB. G. BENTHAM OS TILIAOEiE, 61 



The following is new : — 



A. MBMBBANACEA, Spruce. Foliis supra glabris subtus subcanescen- 

 tibus, panicula laxa per anthesin ebracteata, antherarum membrana 

 loculos 2-3-plo superante. — Fructus A. asperte, a qua differt imprimis 

 panicula ebracteata. Arbor est 25-pedalis, ramis longis, debilibus. 

 Folia fere A. asperce subtus plus minus canescentia v. pallide rufes- 

 centia. Flores iutei. 



Hab. On the banks of the Cassiquiare in Venezuela, but sparingly, 

 R. Spruce, n. 3204 ; near the Bodega de Remolina, in the province 

 of Antioquia, New Grenada, Purdie. 



Prockia, P. Br. (et Linn.) 



The original Prockia cruets, Linn., variously associated by dif- 

 ferent authors with different species of Bixacece, has been again 

 isolated by Bennett and referred by Clos to Tiliacece. This ap- 

 proximation has been confirmed by Seemann, who, in determining 

 his specimens, recognizing in them all the characters of Tiliacece, 

 did not think of searching in Bixacea?, but described them as a 

 new genus allied to Sloanea. Grisebach, however, in his recently 

 published ' Flora of the British West Indies,' proposes to retain 

 the plant in Bixacece, uniting it with Banara under the name of 

 Trilix. In this I cannot agree with him ; for whilst the habit and 

 stipules of ProcJcia are quite as much Tiliaceous as Bixaceous, 

 there is nothing in general character to prevail over the positive 

 distinction of a completely divided ovary with axile placentation 

 and hypogynous stamens in ProcJcia, from the 1-celled ovary with 

 projectiug parietal placentas and perigynous stamens of Banara. 

 And with regard to the name, ProcJcia having been established by 

 the elder Liuuaeus in his genera, must surely prevail over his son's 

 more recent name of Trilix. 



Hasseltia, H. B. et K. 



The perianth is usually described as a calyx with a double row 

 of segments without petals. But in this case, as in Banara, Ho- 

 malium, and other genera exhibiting an analogous structure, it 

 appears to me more in conformity Avith established terminology 

 to consider the outer valvate series alone as sepals, and the inner 

 imbricate series as petals, notwithstanding their sepaloid aspect 

 and persistence. 



Plagiopterox, Griff. 



The opposite leaves, inflorescence, and numerous small flowers, 

 give this plant a habit which does not at first view suggest a
