This form has been referred by recent authors, following Rolfe, to the 

 Asiatic Grewia tiliafolia Vahl. It does not appear to me to be referable to 

 Vahl's species, and is accordingly hei'e described as new. Hooker f. states 

 that Grewia tiliaefolia Vahl is best distinguished by its auricled, falcate 

 stipules, a character that does not at all apply to the specimens cited above. 



GREWIA RiZALENSIS sp. nov. § Eugrewia. 



Species G. rolfei simillima et valde afRnis, differt foliis subtus 

 densissime ubique griseo-stellato-puberulis. 



A small tree. Branches terete, slender, black when dry, 

 glabrous, slightly lenticellate, the branchlets densely and uni- 

 formly stellate-puberulent with cinereous or sometimes ferrugi- 

 nous hairs. Leaves ovate to oblong-ovate, chartaceous, 5 to 10 

 cm long, 2 to 4 cm wide, base rounded, slightly inequilateral, apex 

 acuminate, margins denticulate except in the basal portions 

 which are entire, the upper surface dark-colored when dry, 

 slightly stellate-puberulent, especially on the nerves, the lower 

 surface densely and uniformly covered with grayish, stellate, 

 very short hairs; petioles stellate-puberulent, 1 cm long or less; 

 stipules lanceolate, acuminate, pubescent, deciduous, about 5 

 mm long. Umbels numerous, axillary, solitary or fascicled, 

 similar to those of G. rolfei. Sepals lanceolate, acuminate, or 

 acute, pubescent, 7 mm long, 2 mm wide. Petals membrana- 

 ceous, glabrous, oblong, 2.5 to 3 mm long, 1 mm wide, obtuse or 

 retuse. Ovary densely villous ; style glabrous, 3 mm long. Very 

 young fruits densely cinereous-pubescent.

 leaved form. 



A species manifestly very closely allied to Grewia rolfei Merr., and per- 

 haps not specifically distinct, although differing in its uniform, dense, grayish 

 indumentum on the lower surfaces of the leaves, while G. rolfei is densely 

 puberulent on the nerves only, and with scattered hairs on the surface other- 

 wise, that do not conceal the epidermis of the leaf.
