BRYOPHYLLUM CRENATUM 

 Madagascar Sprouting-leaf 



Native of central Madagascar 

 Family Crassulacea^ Orpine Family 



Bryophyllum crenattim Baker, Jour. Linn. Soc. 20: 139. 1884. 



A glaucous, succulent, glabrous perennial, usually two to three 

 feet tall, sometimes larger, with crenate leaf-blades, and cymes of 

 yellow flowers. The round stems are usually simple below and 

 trichotomously branched above, with the internodes rather long and 

 sometimes marked with purple. The leaves are opposite. The 

 blades are fleshy, oblong or ovate-oblong, obtuse, shaUowly and 

 coarsely crenate, the lower ones two to three inches long, on petioles 

 up to two inches long, cordate, two-eared by the usually incurved 

 basal lobes ; they are light green above, paler beneath, with three to 

 five nerves on each side of the midrib which is prominent beneath; 

 the floral leaves are much smaller. The cymes are corymb-like, and 

 rather loosely flowered, with the pedicels slender and recurved. 

 The nodding flowers are a half to two thirds of an inch long; the 

 calyx is rose-colored, almost globose, with four deltoid teeth; the 

 corolla is yellow, its tube about twice as long as the calyx, the 

 four lobes with rounded tips. The eight stamens are included, in 

 one series, inserted above the middle of the tube ; the filaments are 

 about a quarter of an inch long, with small anthers. The carpels 

 are about a quarter of an inch long, with styles of about the same 

 length. 



This interesting succulent was discovered by Robert Lyall about 

 ninety years ago. It grows well in the ordinary succulent house, 

 and is of easy culture. The specimen from which the illustration 

 was prepared was secured in an exchange with the Royal Gardens, 

 Kew, England, in 1902. 



The genus Bryophyllum contains five known species, all natives 

 of Africa, although one, Bryophyllum calycinum, has become so 

 widely distributed that it appears native in America and Asia.
