GYNOPOGON Forst. 

 (Alyxia R. Br.) 



In the second edition of his Flora de Filipinas, Blanco described four 

 species of Brabejum, of which three, Brabejum concatenatum, B. lucidum, 

 and B. pinnatum, are certainly referable to the genus Gynopogon (Alyxia}, 

 and were reduced by Fi-Villar 1 respectively to Alyxia laurina Gaud., 

 A. stellata R. et S., and A. odorata Wall., which reductions are certainly 

 erroneous, none of these species extending to the Philippines. Of Blanco's 

 species, one only, Brabejum lucidum, is at present definitely known, this 

 certainly being a synonym of Alyxia monilifera Vidal. F.-Villar also 

 enumerates Alyxia torresiana Gaud., a species of the Marianne Islands, as 

 a Philippine plant, which is undoubtedly erroneous. 



Key to the Philippine species of Gynopogon. 



1. Leaves opposite, 7 to 10 cm. long.. Brabejum pinnatum 



1. Leaves whorled. 



2. Leaves in whorls of threes, about 5 cm. long ; 



calyx subtended by two bracts........ Gynopogon monilifera 



2. Leaves in whorls of fours or fives ; calyx subtended 

 by five or more bracts. 



3. Leaves 10 cm. long Brabejum concatenatum 



3. Leaves 2.5 cm. long or less Gynopogon parvifolia 



Gynopogon monilifera (Vidal). (Brabejum lucidum Blanco, Fl. Filip. 

 ed. 2, 40. 1845, ed. 3, 1:74, non Alyxia ludda Wall.; Alyxia stellntu 

 Vidal, Sinopsis, Atlas, t. 67. f. B. 1883; F.-Vill. Nov. App. 129, non 

 R. et S.; Alyxia monilifera Vidal, Rev. PL Vase. Filip. 183. 1885.) 



This species is represented by No. 3857 (Merrill), Mount Mariveles, 

 Province of Bataan, Luzon, August, 1904 (fruit) ; also No. 224 (Wtytford), 

 same locality, May, 1904 (flower). The type material of Blanco's Brabe- 

 jum lucidum was from Cebu, while that of Vidal's Alyxia monilifera was 

 from Mount Banahao, Province of Tayabas, Luzon, No. 401 (Vidal). 

 Gynopogon parvifolia, sp. nov. 



A scandent shrub with whorled, coriaceous leaves 2.5 cm. or less in 

 length, and axillary solitary flowers about 12 mm. long. Branches yellowisli 

 gray, pustular, glabrous, the ultimate branchlets sharply angled. Leaves 

 in whorls of from three to five, elliptical lanceolate, 1 to 2.5 cm. long, 

 0.5 to 10 mm. wide coriaceous, glabrous, the apex and base acute or 

 subacute, the upper surface dark when dry, shining, the lower surface 

 pale, the nerves nearly obsolete ; petioles glabrous, 2 to 3 mm. long. Flowers 

 white, solitary in the axils of the leaves, short pedicelled, subtended by 

 a double whorl of ovate acute, pubescent bracts, 4 or 5 bracts in a whorl, 

 and about one-half as long as the calyx. Calyx about 3.5 mm. long, 

 deeply 5-lobed, the lobes ovate lanceolate, acute, pubescent. Corolla 

 glabrous, about 10 mm. long, the tube cylindrical, about 8 mm. long, slightly 

 enlarged above, the limb spreading, 5-lobed, the lobes ovate, acute, 4 mm. 

 long. Stamens 5, inserted near the apex of the tube, the filaments about
