Sur les Kalanchoe synsepala et K . trichantha; 
par M. Raymond II AM ET. 
Sous le nom de Kalanchoe synsepala, Baker 1 a décrit en 1882 
une Crassulacée malgache qui possède, d’après lui, les carac¬ 
tères suivants : « An erect succulent, perennial, glabrous 
in ail its parts. Lower leaves opposite, sessile, oblong-spathulate, 
1 1/2 in. long, dentate in the upper half. Flowers in dense ter¬ 
minal corymbose cymes; pedicels 1/4-1 /6 in. long; bracts 
very minute, lanceolate or deltoid. Calyx campanulate, greenish, 
1/8 in. long and broad, with four deltoid cuspidate teeth. 
Corolla reddish, 1/2 in. long; tube oblong, 1/8 in. diam.; seg¬ 
ments ovate cuspidate, spreading, a third as long as the tube. 
Stamens 8, inserted near the top of the corolla-tube; filaments 
very short, fîliform ; anthers minute, ovate. Fruit carpels lan¬ 
ceolate, as long as the corolla-tube, narrowed gradually into the 
short persistent styles. Seeds minute, brown, clavate. » 
L’année suivante, Baker 2 décrivit une autre Crassulacée nou¬ 
velle, récoltée elle aussi à Madagascar, le Kalanchoe trichantha.

tubus duplo brevioribus, corollæ luteæ pubescentis segmentis 
orbicularibus quam tubus quadruplo brevioribus, staminibus 
biseriatis, stylo engatolo. An erect perennial, with slender 
terete stems. Leaves opposite, sessile, thickand fleshy in texture, 
green and glabrous on both surfaces, the lower ones reaching 
a length of 5-6 inches, 1 1/2-2 in. broad at the middle, acute, 
sharply and irregularly dentate above the spatulate lower third; 
upper leaves very distant and very small, entire. Flowers in a
