565. Cohort XIV. 



(some almost arbores- 

 cent) with hexamerous 

 and mostly zygomor- 

 phic perianth ; sta- 

 mens six, generally 

 from one to five only 

 polliniferous. 



Order Bromeliacese. 



— The Pine-apple Family. 

 Distinguished from the 

 next by the regular fluw- 

 ers and six perfect sta- 

 mens. About two hundred 

 species of almost entirely 

 tropical plants constitute 

 this order. But one genus 

 {Tillandda) is represented 

 in the Southern United 

 States ; of the eight or ten 



native species, the Long Moss (T. usneoides) of the 

 Southern Atlantic coast is the best known. It is 

 used in upholstery and in the manufacture of mat- 

 tresses. 



Ananassa satma, the Pine-apple, supposed to be 

 a native of Brazil, is now cultivated throughout the 

 world. In cool climates it is grown in hot-houses, 

 and it is said that these are much better than those 

 grown out of doors in warm climates. The fleshy 

 fruits are aggregated into solid cone-like masses (Fig. 

 364), the well-known Pine-apples of commerce. 



Order Scitaminese. — The Banana Family, with 

 zygomorphic perianth, and one to five, very rarely 

 six, perfect stamens. Three sub-orders are well marked.
