CHAPTER XVIL 



DIPLORA, Baker. 

 (Dip-lo'-ra.) 



HIS genus, which comprises but one known species, has been 

 created by Baker, who makes it a sub-division of the genus 

 Asplenium, and in the " Synopsis Fihcum," p. 492, has it 

 as Genus 38*. The name is derived from diploos, double, and 

 lora, thongs, in allusion to the strap-shaped valves of the 

 involucre. Diplora is distinct on account of its sausage -shaped sori (spore 

 masses), which run up the simple vein from the midrib of the frond to its 

 margin. The involucres (coverings of the sori) are also very peculiar, as they 

 are formed of two equal, narrowly -strap -shaped valves, meeting in the middle 

 over the raised vein and bursting open as the spore masses mature. 



Culture. 



D. integrifolia succeeds well under the treatment recommended for 

 Asplenium. It may be increased by means of its spores, which are abundantly 

 produced and germinate freely. 



D. integrifolia — in-teg-rif-ol'-i-a (having entire fronds), Baker. 



In habit, as also in mode of growth, this stove species, native of the 

 Solomon Islands, is similar to Asplenium vittoeforme. Its entire (undivided) 

 fronds, linear-ligulate (narrowly-strap-shaped), of a parchment-like texture, and
