Fig. 298. One of the largest known specimens of the staghorn fern, an epiphyte on trees in 

 the tropics. The upright leaves are the photosynthetic organs ; the rounded leaves pressed 

 against the tree cover masses of roots ; the pendant leaves produce the reproductive bodies. 

 The photograph was made on a small island near Brisbane, Australia.
