AND TROPICAL AFRICA. 163 



I have three different-looking plants from Borneo which may all be referable to Jack's 

 A. dumosa, or some of them to Korthals's Bornean A. trichocarpa and excelsa ; but I have 

 failed to distinguish these by good characters. Motley's best specimens are identical with 

 Malayan and Sumatran ones. 



1. Etjrta, sp. ? 



Hab. In monte Kini Balou insulce Borneo, Low. 



Resembles E. IVigliticma, Wall. I have only a fruiting specimen, in which the large 

 rounded sepals differ much from those of E. nitida, Korth., the only described Bornean 

 species.

obtusis margins spinulosis, stipulis oblique oblongis acutis, paniculse ramulis pube- 

 rulis, bracteolis oblongis acutis, sepalis obtusis margine fimbriolato-spinulosis.

Ab E. leucocarpa. Jack, difFert omnibus partibus duplo majoribus, ramulis robustis, foliis obtusioribus, &c. 

 Folia S"ad pedalia, in petiolum 1-2" long, angustata, 2-3" lata, stipulis oblique ovato-oblongis acutis. 

 Panicula 4" longa, ramis robustis. Bracteolm A" longse. Flores sub |" expansi. Stamina 5, oblique 

 lagenseformia, longe attenuato-rostrata. Fructus E. Jackiance, sed duplo major. 



2. EuTHEMis OBTUsiFOLiA (H. f.) ; foliis anguste obovato-oblongis oblongo-lanceolatisve 



obtusis apiculatis serrulatis, stipulis longe subulatis. 

 Hab. In ora septentrional! insulae Borneo, T. Lobb. 

 Rami teretes, crass, pennffi corvine. Folia 3-4" longa, in petiolum brevem angustata, f-l|" lata. 



I have no flower of this very distinct species, which may readily be known by its 

 blunt leaves and subulate stipules.

acuminatis nervis creberrimis tenuibus, panicuHs axillaribus folio brevloribus flori-

 Hab. In ora septentrionali insulae Borneo, Low. Nom. vern. " Kayuk Bintangur." 

 Arbor 100' {Loiv). Ramuli robusti, teretes, ultimi tetragoni, nigri. Folia coriacea, petiolo l"longo. Pani- 

 culce 3" longse, sub 20-flor8e. Flores subglobosi, fere ^" expansi. Sepala oblonga, valde concava, 

 valvata. Petala late obovata v. orbicularia. Stamina perplurima, filamentis ima basi connatis, an- 

 theris breviter oblongis. Ovarium subglobosum, stigmate late bilobo. Pedicelli fructiferi l" longi, 

 curvi, robusti. Drupa late ovoidea, V' longa. 



Mr. Low remarks that this forms a straight tree, used for masts and in boat-building.
