Malvastrum. Malvaceae. 



Propagated by firm green cuttings under glass in late winter or 

 spring ; sometimes by seeds, when available. 



M alvaviscus . Malvaceae. 



Handled by seeds, and by greenwood cuttings under glass. The 

 familiar M. arboreus (Achania Mahamscus) grows readily from 

 cuttings. 



Mammea (Mammee-Apple. St. Domingo Apricot). Guttiferce. 

 Usually increased by seeds. Cuttings of half -ripened shoots 

 should be placed in a frame. Inarching and budding probably 

 should be practiced for desirable named varieties, on seedling 

 stocks. 



Mammillaria. Cactacece. 



Propagation as for echinocactus, which see. See Cacti, page 261. 



Mandevilla. Apocynacece. 



Handled by seeds, layers and usually by cuttings of half- 

 ripened wood under glass. 



Mandragora (Mandrake). Solanaceos. 



Propagated by seeds and division. The plant usually known as 

 mandrake in the United States is podophyllum, readily increased 

 by division of the new shallow rhizomes, leaving a growing end. 



Manettia (now called Lygistum). Rubiaceos. 



Usually increased by cuttings of young shoots started under glass 

 in a temperature of 60 to 65. Root-cuttings are sometimes made, 

 and seeds are employed when obtainable. This genus now takes 

 the name Lygistum. 



Manfreda. Am-ayllidacece. 



Propagation as for agave, which see. Usually known as agaves. 



Mango (Mangifera indica). Anacardiacece. 



Stocks are readily obtained by seeds. The seeds often have 

 more than one embryo, sometimes as many as ten. Each embryo 

 will produce a distinct plant. The embryos may be separated before 

 planting, but it is preferable to separate the young plantlets soon 

 after germination, before they grow together, as they are apt to do. 

 The seeds germinate better if the hard shell is removed before plant- 

 ing. Seeds retain their vitality but a few days, and if to be shipped
