species, largely tropical, best known in

rosette form (Fig. 127), having close 



clusters of bright flowers with colored 



bracts. Here belongs the Pineapple 



with its multiple fruit, though the plant 



is terrestrial, and also the southern Long 



Moss or Spanish Moss, a remarkable lichen-like epiphyte; 



and many bright-flowered forms are grown in conservatories.
