The vegetative characters of this species are similar to those 

 of Diospyros peregrina (Gaertn.) Gurke (D. embryopteris 

 Pers.), from which it can be readily distinguished by its reticu- 

 lations, although prominent on the lower surface, being obsolete 

 on the upper surface, as well as in its very different persistent 

 calyces. 



DIOSPYROS MACLUREI sp. nov. 



Arbor 12 ad 15 m alta, inflorescentiis fructibusque exceptis 

 glabra, ramis teretibus, ramulis tenuibus; foliis coriaceis vel 

 crasse chartaceis, oblongis ad late oblongo-oblanceolatis, 8 ad 

 12 cm longis, 3 ad 5 cm latis, nitidis, olivaceis vel brunneis, 

 obtuse acuminatis, basi acutis, nervis utrinque circiter 8, subtus 

 valde perspicuis, reticulis laxis; petiolo 8 ad 10 mm longo; 

 floribus $ axillaribus, ut videtur fasciculatis vel breviter race- 

 mosis ; f ructibus oblongo-ovoideis vel subcylindraceis, 8-locellatis, 

 junioribus dense ferrugineo-pubescentibus, vetustioribus glabris, 

 nigris, circiter 5 cm longis et 3 cm diametro ; seminibus paucis, 

 3 ad 3.5 cm longis, albumine aequabile; calycis persistentibus 

 coriaceis, sub fructu circiter 2 cm diametro, ferrugineo-pubes- 

 centibus, ut videtur glabrescentibus, 4-lobatis, lobis suborbicu- 

 laris, patulis vel reflexis, late rotundatis. 



Yik Tsok Mau and Ng Chi Leng, McClure 8657, 8U63, 96U3 

 (type), December, 1921, and May, 1922, on forested slopes and 

 in ravines, altitude about 650 meters. 



My specimen of 8U63 is sterile, although the field note accom- 

 panying it indicates that the flowers are yellowish green; 

 96A3 presents immature fruits, and 8657 fully matured fruits, 

 lacking however the persistent calyces. The species is well 

 characterized by its oblong or cylindric, apparently fleshy, ul- 

 timately glabrous fruits which are black when dry, as well as 

 by its unusually long seeds.
