RHAMNACEiE. 283 



the character of G. denticulata; so that it may be provisionally re- 

 ferred to that species. It is probably the same as No. 1578 of 

 Cuming's Philippine collection. 



3. GOUANIA VITIFOLIA, Sp. Nov. 



Q.foliis membranaceis ovatis rotundisve cordatis subacuminatis creber- 

 rime crenato-dentatis ramulisque glabratis ; stipulis ovatis parvis; 

 spiels brevibus calycibusque rufo-tomentosis ; coccis orbicularis alatis 

 utrinque emarginatis. 



Hab. Sandwich Islands : on dry hills, in the district of Waianai, 

 Oahu. 



Branches shrubby, scandent by involute tendrils, glabrous. Branch- 

 lets, petioles, &c, minutely ferrugineous-pubescent, at least when 

 young. Leaves membranaceous, one and a half to 2 inches, or more 

 in length, one to 2 inches wide, ovate or roundish, cordate, with a 

 narrow sinus, somewhat acuminate, except the earlier ones, which are 

 very obtuse, closely crenale-toothed, the obtuse teeth furnished with 

 glandular tips, glabrous above, softly and minutely pubescent, but 

 soon glabrate underneath, triple-nerved from the base, and with 

 straight and approximate primary veins. Petioles 3 to 6 lines long. 

 Stipides ovate, acute, a line long. Spikes short, or at length equalling 

 the leaves, axillary and terminal, dense, especially the upper part, 

 which bears the sterile flowers ; the rhachis, calyxes, and minute oval 

 bracts clothed with a dense and fine ferrugineous or reddish tomentum. 

 Lobes of the disk emarginate. Fruits very short-pedicelled, mostly 

 tricarpellary, when young ferrugineous-pubescent, obovoid, and en- 

 tirely wingless ; but the mature carpels moderately winged, orbicular 

 in outline, slightly emarginate at both ends, glabrate, about 5 lines in 

 diameter. 



This species considerably resembles Q. tilicefolia, especially in its 

 inflorescence ; but the stems are glabrous, the leaves (which resemble 

 those of a Vitis or a Tilia on a small scale) are closely beset with 

 even and rather coarse teeth ; the stipules are shorter and broader ; 

 and the mature carpels are winged.
