PHRAGMOPEDILUM 



PHRAGMOPEDILUM 



Selenipedium in Cyclo. Amer. Hort. The genus Seleni- 

 pedium is still retained by botanists, however, with 

 which Phragmopedilum agrees in the 3-celled ovary but 

 from which it differs in habit, conduplicate coriaceous 

 strap-shaped Ivs., the fl. being articulated above the

ovary and deciduous, and the seeds 

 being fusiform. The orthography of 

 the name is somewhat confused. The word 

 was originally spelled Phragmopedilum as a 

 section of Paphiopedilum, and this form is 

 adopted by Pfitzer and by Index Kewensis. 

 Rolfe, the English authority, at first wrote it Phragmi- 

 pedium and more recently Phragmipedilum. (See dis- 

 cussion by him in Orchid Review, 9, 174, 175.) 



All phragmopedilums enjoy plenty of heat and mois- 

 ture in the growing season, March to November (65 

 to 90). Give good drainage. Use chopped sphagnum 

 with broken clinkers from the furnace, and the addi- 

 tion of a little leaf-mold, raising the material as high 

 above the rim of the pot as possible. This material is 

 especially to be recommended for the young and divided 

 plants. Give slight shade, and grow on raised benches 

 near the glass. Water sparingly until growth begins. 

 The four species, P. Dominianum, P. Sedenii, P. 

 Schlimii and P. Sargentianum, should not be overpotted. 

 Fill pots three-fourths full of drainage, then place a thin 

 layer of coarse fern-root, which will fill pot to level of the 

 rim. Place the plant on top of this and then fill 2 j^ to 3 

 inches with chopped sphagnum and leaf-mold mixed 

 with coarse sand or pulverized coal-clinkers. Keep the 

 moss in a growing condition. (Wm. Mathews.)
