(Originaldiagnosen.) 
1. Mastixia Margarethae Wangerin, nov. spec. 
Arbor, ramulis teretibus alutaceo-cinerascentibus vel -fuscescentibus 
novellis appresse pilosulis demum glabratis. Foliorum alternorum petio- 
lus supra canaliculatus glabratus ?/,— 1 em longus, lamina coriacea, in 
sieco saturate olivaceo-virescens subtus pallidior, supra glaberrima subtus 
secus costam mediam parce breviterque appresse pilosa ceterum glabrata, 
bene elliptica vel oblonga basi in petiolum angustata apice acuminata 
acumine rotundato, ad 6,5 em longa et 2?/, cm lata, costa nervisque 
lateralibus primariis areuatim adscendentibus supra manifeste immersis 
subtus prominentibus, nervillis supra vix manifestis subtus interdum 
prominulis. Pannieulae defloratae tantum mihi visae pauciflorae distractae 
subglabrae; flores tetrameri bracteolis minimis instructi; calycis limbus 
+ 1/, mm latus omnino non vel minutissime 4-dentatus (in drupa per- 
fecte truncatus); stylus conieus */, mm longus tetragonus, stigmate sub- 
bilobo. Drupa longe ellipsoidea in sicco nigrescens glaberrima apice 
calycis limbo et disco coronata, 2,5 cm longa, ?/, cm diametro metiens. 
Sumatra occidentalis: Prov, Padang, am Meeresstrande (Beccari 
no. 956). — Herbar Leiden. 
Der M. tetrandra C. B. Clarke nächst verwandt, mit der sie die 
wechselstündigen Blütter und die ellipsoidische Fruchtgestalt teilt, wührend 
sie sich durch die Blattform sowie vor allem durch den fast ganz- 
randigen Kelchsaum deutlich unterscheidet. 
2. Mastixia Korthalsiana Wangerin, nov. spec. 
Arbor, ramulis teretibus novellis ochraceis pilis subcrispidulis vel 
appressis densiuscule obtectis demum glabrescentibus ochraceo-brunnes- 
centibus vel-fuseescentibus. Foliorum stricte oppositorum petiolus supra 
manifeste canaliculatus item densiuscule pilosulus 1!/,—1?/, cm longus, 
lamina coriacea in sicco olivaceo-virescens vel nigrescens, adulta supra 
glaberrima subtus nunc omnino glabrata nunc secus nervos principales 
+ disperse breviterque pilosula, nune lanceolate nunc bene (saepius sat 
anguste longeque) vel rarius subovato-elliptica basi in petiolum angustata 
apice acuminata, costa media nervisque lateralibus primariis subarcuatim 
adscendentibus margine non conjunctis supra immersis subtus valde 
prominentibus, nervis secundariis supra manifestis subtus prominulis, 
venis reticulatis utrinque vix manifestis. Panniculae defloratae tantum 
mihi visae valde distractae, bracteis ut videtur minutis ovato-triangularibus 
minutiusculis instructae parce pilosulae vel subglabrae; flores pentameri, 
sepalis in drupa bene vel lanceolato-triangularibus 1 mm longis. Drupa 
onge ovoidea glaberrima in sicco cinerascens vel fusco-nigrescens, apice
