PALMERVANDENBROEKIA Gibbs, gen. nov. 
Flores polygami. Sepala 5-dentata, basi dentibus lata, apice acuta vel acu- 
minata. Petala 5, valvata, longe lanceolata, basi lata leviter adherentia, apice 
sensim attenuata, acuta, demum recurvata. Stamina 5, antheris dorsifixis, oblongis. 
Ovarium parvum, inferum, biloculare, loculis uniovulatis, ovulo ad apicem loculi 
pendulo, minuto, micropyle supera, raphe ventrali, discus planus, stylus magnus, 
pyramidato-connatus. Folia imparipinnata, foliola integra, petioluli basi articu- 
lati. Umbella parva, terminalis, pauciflora, pedicelli floribus circiter aquilongi, 
apice articulati. 
This genus is intermediate between Aissodendron and Polyscias. In the 
pyramidal connate style it resembles the former, but in form of calyx, petals 
broad at the base and slightly cohering, with the 2-celled ovary, it is nearer 
the latter. In the small imparipinnate leaves and simple umbels it, indeed, 
somewhat resembles the most reduced forms of Polysctas sambucifolius 
(Lieber) Harms, in habit. As a genus it is distinct in the long tapering 
petals, separating at the apex and subsequently recurved, in the massive 
style, and extremely small ovary.

In the only specimen of this interesting plant the cortex is striate, light 
grey in colour, thin and papery. The leaves are greenish grey when dried, 
8 cm. by 3-4 cm., including the 4-angled petiole + 2 cm. long ; the petiolules 
are slightly 4-winged, *5 cm, long; the lamine of the largest folioles are 
+ 4:5 by 1:2-1'4 cm., the latter are often oblique, broader on one side 
than the other, the midrib prominent and projecting on both surfaces with 
5-7 inconspicuous lateral veins, parallel in arrangement. Single umbels 
1:5-3'5 by 16 cm. deep, on peduncles + 2 em. long; pedicels 7-8 mm. 
long, each subtended by a minute scale. Petals 8-5 by 14mm. Anthers 
1 mm., filaments 2 mm. long. Ovary and style 3:2 mm. long, the style 
2 mm. long and 1 mm. broad at base. 
It isa great pleasure to name this interesting new genus after Mr. Palmer
