 level of the sea. Besides the ordinary method by- 

 seed, it propagates itself by runners which it throws 

 out from the base of the flower-stem. This runner 

 is always found directing itself towards the nearest 

 Tillandsia, when it inserts its point into the water 

 and gives origin to a new plant, which, in its turn,

 not less than six plants united. The leaves, which 

 are peltate, measure upwards of three inches across, 

 and the flowering stem, which is upwards of two feet

 kinds, if grouped in accordance with their habits. 

 One group would consist of those which float freely

 species which, like the Brazilian one, are epiphytal 

 or terrestrial, though loving moist places. A third 

 group might almost be constituted of species which 

 live in the crannies of rocks and bear bladder's 

 attached to their root-like underground stems. Yet, 

 whatever their peculiar habit may be, the bladders in
