those of some of the forms of the gen us Rhipsalis among the cactus 

 family in the immediate neighborhood. Large specimens of two 

 of these species, E. Nivulia and E. Tirucalli, will be found with 

 the E. lactea in house no. 6. Another genus of this family is 

 Pt-dilanlhns, confined to tropical America, of which there are 

 several species represented. The members of this genus have 

 been given the common name of slipper-spurs. 



The stonecrop family, Crassulaceae, besides the large collec- 

 tion in house no. 5, has a few representatives here, species which 

 require warmer treatment than can be accorded them in the house 

 referred to. The sprouting-leaf plant, Bryophyllum calycinum, is 

 widely distributed in tropical America, its original home probably 

 being in Mexico. It receives the name of sprouting-leaf from the 

 ease with which it can be propagated from the leaves. A leaf laid 

 down on moist sand will send up numerous plants from the in- 

 dentures along its margins, each of which, if properly cared for, 

 will grow into a large plant. The genus Kalanchoe, also of this 

 family, is Old World in its distribution, and has some showy 

 members among it. Kalanchoe flammea, from tropical Africa, 

 with its flame-colored flowers, is quite frequently seen in cultiva- 

 tion. Another species, K marmorata, from Abyssinia, is quite 

 different in appearance, with large white tubular flowers three to 

 four inches long, and gray-green leaves mottled with brown, the 

 whole overcast with a whitish bloom. 



Opposite to this is another group of the spurge family, Euphor- 

 biaceae, including those which have more the appearance of 

 ordinary plants. One of these was quite popular some years ago 

 under the name of the chenille plant, or Philippine Medusa. It 

 is an old plant of the East Indies, described many years ago as 

 Acalypha hispida, and rechristened in 1896 as Acalypha Sanderi. 

 Its long and pendulous inflorescence certainly bears a strong 

 resemblance to the old-time chenille and makes very appropriate 



of tropical America, but widely cultivated in tropical regions gen- 

 erally for its seeds, which are known as physic-nuts or Barbados 

 nuts. These seeds, together with those of Jatropha multifida, 

 yield jatropha-oil. The snow-bush, Phyllanthus nivosus, of the
