51. MEGALOCHLAMYS, Lindau in Engl. Jahrb. xxvi. 345. 
Sepals 5, nearly distinct, small, subequal, linear or linear-lanceo- 
late. Corolla 2-lipped; tube linear-cylindric, rather shorter than 
the lobes; anticous lip 3-fid; posticous lip ovate-oblong, subentire. 
Stamens 2; anthers long-exserted, 2-celled, muticous; cells linear- 
oblong nearly at equal height; pollen ellipsoid, smooth, with 
two stopples. Pistil glabrous; ovules 2 in each cell; style very 
shortly and equally 2-lobed at the tip. Capsule stalked, ovoid, 
much flattened, usually 2-seeded; placente not rising elastically 
from the base of the capsule-valves; seeds rather large, much com- 
pressed, glabrous, somewhat tubercular-scabrous.—Shrubs. _ Leaves 
entire. Inflorescences terminal and axillary; floral leaves imbricated, 
with (commonly) 3 flowers in the axil of 1 or 2 of the upper; bracts 
and bracteoles 0 or only represented by bristles hardly ;',; in. long. 
Species 3, endemic. 
Engler & Schinz referred these plants to Dicliptera, which is untenable, as the 
placentz do not rise elastically from the capsule valves ; the inflorescence, moreover, 
is totally different, being that of Phaylopsis, The genus differs from Ecboliwm, sect. 
Choananthus, mainly in the inflorescence. 
Glabrous, or nearly so.

1. M. Marlothii, Lindau in Engl. Jahrb. xxvi. 345. Glabrous, 
except the calyx. Leaves 14 by 3 in., tip triangular, base obtuse ; 
petiole 0-4, in. long. Inflorescences 3-1 in. in diam., nearly enclosed 
by the two lowest floral leaves, which are 3 by # in., ovate, acute, 
with reflexed margins ; upper floral leaves 4 by }-1 in. ; flowers 3-1 
in the axil of the penultimate floral leaf Gnd sometimes of 1 or 2 
adjacent). Calyx 4-1 in. long, minutely pubescent. Corolla j-1 ™. 
in total length. Filaments glabrous. Capsule 4 in. long, upper 
flattened part } in. broad; seeds discoid, tubercular-scabrous, not 
hairy.— Dicliptera Marlothii, Engl. in Engl. Jahrb. x. 266. D. schu-
