somewhat winged by the decurrent lamina ; stipules short, wide, 
ending in a prominent but stout and blunt apiculus, sometimes 
with two very short, obscure lateral appendages, not laciniate. 
Inflorescence terminal, peduncled, usually, however, with two 
basal branches which are scarcely longer than the peduncle of 
the inflorescence proper, the whole inflorescence up to 12 cm 
long, dark-colored or nearly black when dry, lax, or the flowers 
somewhat crowded, 6 to 9 cm in diameter, the bracts subtending 
the primary branches linear-lanceolate, acuminate, 5 to 7 mm 
long. Flowers numerous, 4-merous, white, quite glabrous. 
Calyx black when dry, the tube funnel-shaped, 1.5 mm long, with 
4, short, triangular-ovate, acute, 0.5 mm long teeth. Corolla 
nearly black when dry, the tube 4 mm long, slightly enlarged up- 
ward, the lobes 2.5 mm long, oblong-ovate to ovate-lanceolate, 
acute or acuminate. Anthers oblong-lanceolate, 1.8 mm long, the 
filaments very short. Capsule turbinate, 3.5 mm in diameter, 
base somewhat acute, apex truncate, the crowning teeth not 
prominent. 
R. C. McGregor 572 (type), Cabras Island, October, 1911, G. E. S. 239, 
January, 1912, on rocks at Asan. 
A species apparently well characterized by its obscurely nerved, short- 
petioled leaves, its nearly entire, not at all pectinate stipules, its small 
calyces, and its distinctly dark color in drying.

A native of tropical America, introduced into Guam through the medium 
of the Acapulco-Manila galleons; reported also from Samoa. The credit- 
ing of M. torresianum C. & S. to Guam was not due to any mixing of labels, 
as suggested by K. Schumann and Lauterbach.
