MERRILL AND MERRITT. 
COLEUS Lour. 
1. C. macranthus Merr. in Philip. Journ. Sci. 1 (1906) Suppl. 234. 
Common in the mossy forest, Merrill 660 If, C. M. Z. 161Jf6. 
Known only from high altitudes in the Benguet-Lepanto region. 
2. C. crispipilus Merrill comb. nov. 
Coleus macranthus var. crispipila Merr. 1. c. 
In the mossy forest, Merrill 6553, McGregor 8896, C. M. Z. 16066. 
Like the preceding known only from high altitudes in the Benguet-Lepanto 
region; I am now of the opinion that this form is worthy of specific rank. The 
fresh plant is aromatic when crushed. 
3. Coleus zschokkei Merrill sp. nov. 
Suflruticosus, erectus, circiter 60 cm altus, ramulis, foliis, inflores- 
centiisque cinereo-puberulis ; foliis parvis, elliptico-ovatis vel ovatis, acutis 
vel acuminatis, circiter 3 cm longis, subtus dense glandulosis ; inflores- 
centiis circiter 15 cm longis; calycibus fructiferis declinatis, intus nudis, 
dentibus lateralibus brevibus, truncatis. 
Suffrutescent, erect, about 60 cm high, branched, the stems about 8 
mm in diameter, the branches stout, obscurely 4-angled, brown, puberulent. 
Leaves elliptic-ovate to elliptic, rather thin, densely gray-puberulent, 
about 3 cm long, 1 to 1.5 cm wide, beneath strongly and densely glandular- 
punctate, the apex acute or acuminate, the base acute, margins crenate 
or crenate-dentate in the upper two-thirds; nerves about 4 on each 
side of the midrib, ascending; petioles puberulent, 3 to 10 cm long. 
Inflorescence about 15 cm long, puberulent, the verticils of lax, 1.5 
cm long, few-flowered cymes. Flowers purple, the pedicels pubescent, 
slender, about 5 mm long. Calyx glandular and pubescent, 5.5 mm 
long in fruit, declinate, glabrous within, the lower lip oblong-lanceolate, 
about 4 mm long, cleft into two, lanceolate, acuminate, 0.8 mm long 
teeth; upper lip much shorter, 3-toothed, the middle tooth elliptic- 
ovate, rounded, 2 mm long, the two lateral ones rectangular, truncate, 
1 mm long and wide. Corolla purple, with minute, scattered glands, 
and slightly ciliate, 8 mm long, the tube slender, deeurved; upper lip 
broad, irregularly lobed, about 2 mm long, the lower one boat-shaped, 
somewhat hooded, 5 mm long. Upper portions (2.5 mm) of the filaments 
free, the remainder connate into a tube. Nutlets rounded, compressed, 
black, shining, 1 mm in diameter. 
In stream depression, lower pine region, Merrill 6529 (type), and in grass lands 
in the open pine region, altitude about 1,700 m, C. M. Z. 16325. 
Quite different from any of the other Philippine species of the genus; recog- 
nizable by its comparatively small leaves, and by its grayish puberulence.
