par M. Raymond HAMET. 



Sous le nom de Kalanchoe synsepala, Baker 1 a decrit en 1882 

 une Crassulacee malgache qui possede, d'apres lui, les carac- 

 teres suivants : « An erect succulent, perennial, glabrous 

 in all 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 lour 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, filiform ; 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'annee suivante, Baker 2 decrivit une autre Crassulacee nou- 

 velle, recoltee elle aussi a Madagascar, le Kalanchoe trichantha. 

 Voici la diagnose originale de cette espece : « Erecta, elata, 

 foliis inferioribus magnis sessilibus oppositis oblongo-spathu- 

 latis acutis serratis glabris, floribus in paniculas densas niulti- 

 floras terminales corymbosas aggregatis, pedicellis brevissimis 

 pilosis, calycis pilosi campanulati segmentis deltoideis quam 

 tubus duplo brevioribus, corolla- lutese pubescentis segmentis 

 orbicularibus quam tubus quadruplo brevioribus, staminibus 

 biseriatis, stylo engatolo. An erect perennial, with slender 

 terete stems. Leaves opposite, sessile, thick and 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
