Vigna lutea. Seaside bean. 



A trailing, yellow-flowered, perennial plant growing on sandy beaches. Leaves 

 trifoliolate; stipules minute, lanceolate, attached by the base; leaflets obovate, 

 obtuse, rather fleshy, entire, glabrous; racemes many-flowered, long-peduncled; pods 

 short, few-seeded, resembling those of Phaseolus. 



It is possible that the allied Vigna luteola occurs in Guam, although I have not 

 found it on the island. It differs from the preceding in having acute, membranous 

 leaflets, the lower tooth of the calyx lanceolate, as long as the tube, and the pod 

 recurved, containing 6 to 12 seeds.

Family Verbenaceae. 

 Local names. — Lagundi (Guam, Philippines); Nika (Ceylon). 



A shrub or small tree, with palmately compound aromatic leaves and cymes of 

 small lilac-blue flowers. Branchlets 4-cornered, finely pubescent; petioles slender, 

 pubescent, 4 to 6.5 cm. long; leaflets 3 or 5, the two lowest smaller and nearly sessile, 

 the others long-stalked, 7.5 to 10 cm. long, linear-lanceolate, acute and often unequal 

 at base, tapering to a very acute apex, nearly glabrous above (when mature), covered 

 with a dense, white, fine pubescence beneath; flowers numerous on very short pu- 

 bescent pedicels; cymes small, stalked, opposite, on erect branches of an erect, pyram- 

 idal, terminal panicle; bracts caducous; calyx small, pubescent, segments 5, very 

 short, triangular; corolla pubescent outside, tube hairy within, the 4 upper lobes 

 short, triangular, lowest one large, rounded, forming lower lip; drupe under 6 mm. 

 long, nearly globose, black. 



The leaves are aromatic when bruised. In India pillows are stuffed with them 

 and are said to relieve headache. The leaves and root are used medicinally, and are 

 said to be tonic. This species was collected by Lesson and Gaudichaud in Guam, 

 and given in Endlicher's Flora der Siidseeinseln as Vitex incisa Lam. Growing in 

 low places and on the borders of streams.

A shrub resembling Vitex negundo, but with lighter-colored flowers and leaves 

 sometimes simple and sometimes 3-foliolate. Bark smooth, pale gray; lateral leaflets 

 smaller than the terminal; leaflets sessile, tapering to base, obtuse, all entire, glab- 

 rous above, very finely and closely white-pubescent beneath; petiole about \\ cm. 

 long, pubescent, flowers on short pedicels; cymes paniculate, 1\ cm. long, pubes- 

 cent; bracts minute; calyx white-pubescent, enlarged in fruit, segments obscure; 

 corolla pubescent outside, tube cylindrical funnel-shaped, 6 mm. long, mouth oblique, 

 upper lip with 2 obtuse lobes, lower 3-lobed, the middle one much the longest; sta- 

 mens 4, didymous, much exserted; ovary 2 or 4-celled; ovules 4; stigma bifid; drupe 

 globose, about 6 mm. in diameter, the lower half or more closely invested by the 

 enlarged calyx, slightly scurfy, purplish black, stone usually 1-celled by abortion. 



A shrub usually growing in swampy places near the coast, differing from the pre- 

 ceding species in having obtuse leaflets. The leaves are pleasantly aromatic when
