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 adhaBrentia, 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, pauci flora, pedicelli floribus circiter sequilongi, 

 apice articulati. 



This genus is intermediate between Kissodendron 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 Polyscias 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. 



PALMERVANDENBROEKIA PAPUANA Gibbs, sp. nov.

 foliola 7, breviter petiolulata, oblique obovata vel oblanceolata, basi cuneata, apice 

 attenuata, angusta, abrupte emarginata vel obtusa, integerrima, incurva, inem- 

 branaceo - chartacea. Umlella parva, terminalis, 6-7 - flora, pedunculata, basi 

 bractea unica, foliolis simili. Petala albida, longe lanceolata, apice attenuata 

 acuminata. Calyx repandus, 5-dentatus. Stamina erecta, filamentis quam antherse 

 triple longioribus. Stylus unicus, conicus, elongatus. Discus planus. Ovarium 

 parvum, biloculare, in sicco sulcatum. Fructus ignotus. 



Hob. Arfak Mts., Angi lakes, on S.W. ridge, in shrubby growth, 8000'. 

 Fl. Dec. 6003. 



In the only specimen of this interesting plant the cortex is striate, light 

 grey in colour, thin and papery. The leaves tire 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 laminse 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 

 l'5-3'5 by 1'6 cm. deep, on peduncles + 2 cm. long ; pedicels 7-8 mm. 

 long, each subtended by a minute scale. Petals 8'5 by 1'4 mm. 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 is a great pleasure to name this interesting new genus after Mr. Palmer
