PHILIPPINE PLANTS, IX. 345 



the index in the last volume of Rumphius' work. So far as sterile material 

 is comparable with the figure, I consider Rumphius' delineation to be an 

 excellent representation of the Philippine plant. Coleus amboinicus Lour, 

 is the type of the genus. 



MESON A Blume. 

 MESON A CLAUSA sp. nov. 



Herba erecta, stricta, vix ramosa, circiter 30 cm alta, caulibus 

 foliis inflorescentiisque plus minusve dense pallide f ulvo-villosis ; 

 foliis petiolatis, oblongis, usque ad 6 cm longis, obtusis vel 

 acutis; inflorescentiis interruptis circiter 15 cm longis, verticillis 

 densis, subglobosis; calycibus sub fructu plus minusve inflatis, 

 8 mm longis, 2-labiatis, labiis integris, inferioribus orbicula- 

 ribus OS calycis claudentibus, superioribus oblongis. 



An erect unbranched herb about 30 cm high. Stems rather 

 stout, obscurely angled, rather densely covered with pale-fulvous, 

 villous hairs. Leaves oblong or narrowly oblong, 5.5 to 6 cm 

 long, 1 to 1.5 cm wide, apex acute or obtuse, base acute, the 

 margins somewhat crenulate, both surfaces more or less villous, 

 especially on the nerves and midrib; nerves ascending, about 

 8 on each side of the midrib; petioles 5 to 10 mm long, those 

 of the basal leaves sometimes 2 cm in length. Inflorescence 

 interrupted, about 15 cm long, the whorls dense, globose, 2 to 

 2.5 cm apart, the upper ones closer, about 1.5 cm in diameter, 

 the rachis densely villous, the bracts subtending the whorls 

 oblong-ovate, brown, reflexed, more or less villous, acuminate, 

 0.8 to 1.5 cm long, the lowermost ones subfoliaceous. Calyx just 

 after anthesis 3 mm long, densely villous, in fruit accrescent, 8 

 mm long, slightly inflated in the middle, the mouth oblique, closed 

 by the orbicular lower lip which is 2 mm in diameter and 

 villous on the outside, entire, the upper lip oblong, 1.5 mm long, 

 obtuse, not at all lohed or toothed, villous on the outside. Co- 

 rolla unknown. 



CULION, in damp, open grass lands, Merrill ^60, December 13, 1902. 



A species well characterized by its entire calyx-lips, the lower one 

 orbicular, appressed to and quite closing the mouth of the calyx-tube. I 

 have found on the specimen a single badly withered corolla showing the four 

 stamens, the upper two filaments appedanged at the base, characteristic of 

 the genus.
