CASEARIA LEUCOLEPIS Turcz. in Bull. Soc. Nat. Mosc. 31 (1858) 463. 



Sarawak, Baram District, Baram, Hose 79, December, 1894. 



This species was originaly described from Singapore, based on Lobb J>68 

 so localized. In some herbaria, however, Lobb's plant is localized as 

 "Luzon." Lobb collected in Singapore, Java, Borneo, and Luzon, and it is 

 a well-known fact that his specimens were often erroneously localized; see 

 Merrill in Philip. Journ. Sci. 10 (1915) Bot. 184. King 1 does not recognize 

 the species as occurring in the Malay Peninsula, and Stapf ' gives its range 

 as from Java and Borneo to the Philippines. Koorders,' however, does not 

 admit it as Javan. It is probable that Lobb's specimen was from Borneo, 

 not from Luzon, Java, or Singapore. I have seen no Philippine material 

 that I can refer to Casearia leucolepis Turcz. Hose's specimen cited above 

 agrees very closely with the fragment of Lobb's plant that I have for 

 comparison, and I believe that they represent the same species. 



CASEARIA IMPRESSINERVIA sp. nov. 



Arbor, ramulis, subtus foliis ad costa nervisque floribusque 

 griseo- vel cinereo-puberulis vel pubescentibus ; foliis oblongis, 

 coriaceis, integris, acute acuminatis, basi acutis, usque ad 8 cm 

 longis, nervis utrinque circiter 8, curvato-adscendentibus, prom- 

 inentibus, supra impressis; floribus 5-meris, axillaribus fasci- 

 culatis, breviter pedicellatis, sepalis 3.5 mm longis, obtusis; 

 staminibus fertilibus 10, staminoideis anguste oblongis, sursum 

 dense villosis; ovario glabro vel supra leviter ciliato. 



A tree, size not indicated, the branches and branchlets nearly 

 black when dry, the former glabrous, the latter somewhat pubes- 

 cent or puberulent, somewhat angled, the internodes about 1 cm 

 long. Leaves coriaceous, oblong, entire, 6 to 8 cm long, 2 to 3 

 cm wide, sharply acuminate, base acute, equilateral or nearly 

 so, the upper surface quite glabrous, dark-brown and shining 

 when dry, the lower somewhat paler, pubescent with short, 

 rather pale, spreading hairs along the midrib and lateral nerves ; 

 lateral nerves 8 on each side of the midrib, curved-ascending, 

 prominent, distinctly impressed on the upper surface, obscurely 

 anastomosing, the reticulations very slender; petioles 7 to 10 

 mm long, somewhat pubescent. Flowers rather numerous, in 

 axillary fascicles, their pedicels slightly pubescent, about 2 mm 

 long. Sepals 5, oblong, obtuse, somewhat pubescent, about 3.5 

 mm long. Stamens 10, the longer about 2 mm in length, the 

 alternating five slightly shorter; staminodes narrowly oblong, 

 densely villous above, nearly glabrous below, about 1.2 mm long. 

 Ovary narrowly ovoid, glabrous, or the upper part and lower
