BOSTON FERN SPORELINGS. 



Has any one ever grown plants 

 from spores of the Boston fern or any 

 of its varieties? 



Two reports liave come to the 

 writer of the development of spore- 

 growni plants from Xephrolcpifi hoston- 

 iejisis. The reports come from widely 

 separated localities and growers, but 

 agree more or less as to details. Un- 

 fortunately the results were obtained 

 years ago. and none of the plants so 

 produced are now alive. 



The writer is interested in getting 

 information as to any authentic cases 

 of the Boston fern being grown from 

 spores, and will especially welcome 

 an opportunity to see living plants so 

 produced. X. WittboJdi was supposed 

 to be a spore sport from hofitoniensis 

 but the character of all the plants 

 which I have obtained under the name 

 of Wittboldi seem to indicate that it 

 is a form of some Malayan species. 

 :^^ nItiladcJphiriiais. a chance spore- 

 ling at Horticultural Hall, Fairraount 

 Park, Philadelphia, seems to be the 

 same as A', u-ashingtoniensis, itself, I 

 believe, a chance sporeling. and both 

 are undoubtedly to be identified with 

 another Malayan species, sometimes 

 called X. flocrifjrra. These are all 

 broad-leaved forms, very different from 

 tostoniensis or exaltata. \. Elms- 

 fordi. reported as a sporeling from 

 Whitmnni. stands, I believe, as the 

 only form in the Boston fern series 

 credited with this origin. 



Information is asked therefore on 

 the follow'ing points: 



1. Is there any known instance of 

 the development of plants from Boston 

 fern spores? 



2. From the spores of any variety 

 of the Boston fern? 



3. What were the characteristics oi 

 the plants so grown? 



If living plants are now being grown, 

 the writer would like an opportunity 

 to call and see them if near New 

 York, and in any event would be glad 

 to receive small plants for wliich an 

 exchange from a list of a hundred 

 named forms is now available. It may 

 be noted that microscopic examina- 

 tions so far made have shown com- 

 plete sterility of spores among Boston 

 fern forms, but it is not impossible 

 that they may occasionally iiroduce 

 fertile spores.

The Bougainvilleas should be pruned 

 back and repotted now in a compost 

 of turf and cow manure well-rotted. 

 A little sand should be added unless 

 the turf was cut from a sandy soil. 

 Add also a little coarsely ground bone. 

 Keep the ijlants growing along, giving 

 a winter temperature from 45 to 50 

 degrees. 



The La France roses have probably 

 been enriched too much with nitrogen, 

 or may be growing in partial shade. 

 Transplant to a place in full sun. to 

 which has been applied some barn 

 yard dressing at least two years old 

 and a sprinkling of ground lione over 

 the surface.
