LABI AT AE 

 Gomphostemma cinerea Em. n. sp. 



Several stemmed suffrutescent plants 1 to 2 m. high. 

 Stems angular, crooked, occasionally short branched, 

 grayish brown tomentose. Leaves divaricate, opposite, 

 few, mainly toward the top, oblong, the average lami- 

 na 2 dm. long by 8 cm. wide, membranous, glabrate 

 on the upper much darker green side, the obtuse base 

 entire, otherwise crenately toothed or merely apiculate, 

 the acuminate point usually somewhat curved, stellately 

 cinereous beneath especially along the midrib and larger 

 nerves, upon 1 to 3 cm. long densely pubescent petioles; 

 midrib pronounced beneath, with 5 to 8 ascendingly 

 curved nerves on each side, reticulations conspicuous, all 

 grayish white in the dry state. Inflorescence erect, 

 fascicled from the axils of the leaves or their scars, 

 2 to 4 cm. across, stellate tomentose; flowers short ped- 

 icelled, subtended by unequally long bracts varying 

 from linear to oblanceolate or even setaceous in shape; 

 calyx longitudinally corrugate, at least 1 to 1.5 cm. long, 

 gradually expanded from the base to the 5 subulate 

 teeth; corolla 3 to 4 or 4.5 cm. long, minutely stellate 

 on the exterior except the basal portion, pure white, 

 the basal one half slenderly tubular, gradually be- 

 coming inflated toward the top, obscurely or broadly 

 3-lobed at the upper portion of the apex, the tip much 

 extended into a broad laminate lobe which is usually 

 notched at the apex; stamens 4 or 5, subequal, about 

 as long as the corolla; filaments ribbon like, the apical 

 free portion with few tack-shaped hairs; anthers dorsi- 

 fixed, oblong, 2 mm. long, the basal portion divided; 

 style filiform, glabrous, free, equalling the stamens, 

 ending in an unequally notched stigma; ovary ciliate at 

 the top of the 4 lobes, otherwise glabrous. 



Type specimen number 17836, A. D. K. Elmer, Los 

 Bafios (Mt. Maquiling), Province of Laguna, Luzon, June- 

 July, 1917. Along stream beds of dense forests half 

 way up the mountain. 



Distinct from typical Gomphostemma philippinarum Benth. 

 by its larger leaves which are much less pubescent and 

 bv the nearly twice as long corolla.
