BOTANY. The science 

 which treats of plants ; plant- 

 knowledge. In Its widest 

 sense, and properly, it in- 

 cludes much that, by com- 

 mon consent, is usually in- 

 cluded in horticulture,— as 

 amelioration of plants by 

 domestication, hybridizing, 

 aud the like. 



BOTRfCHIUM (Greek, in 



allusion to the grape-like 

 sporangia). OpMoglosscicem. 

 Native Perns of woods and 

 pastures, with fleshy roots, 

 broad temate Ivs., and 

 sporangia borne in a pani- 

 cle, which branches from the 

 common st. Grown in the 

 hardy border, or against a 

 building on the shady side. 

 They require no special 

 treatment, and are little cul- 



large enough to make a display.

BOTTOM HEAT. Said of soil temperature which is 

 higher than that of the superincumbent air. Most ten- 

 der plants require to have the roots warmer than the 

 tops, particularly when grown under glass.
