Pelecyphora 



Pellsea 



PELECYPHORA. (HATCHET CACTUS.) 

 There is one species in this genus (ord. Cactese) 



which is allied to Mammillaria. Propagation, by 



seeds, also by offsets when they can be obtained. 



{See CACTUS for particulars of other cultural 



matters.)

PELLSEA. (CLIFF BRAKE FERN.) 



Description. An important genus of handsome 

 Kerns (tint. Filices), all easily grown. Most of 

 thorn llourish in a greenhouse temperature. Many 

 have a habit similar to the Cheilanthes. The 

 fronds are pendent or sub-pendent, and show to 

 advantage when the plants arc grown in baskets. 

 Falcata, hastata, and rotundifolia are very nearly 

 hardy. Hastata is good for the dwelling-room. 



Propagation. By spores, which germinate freely 



Pelican Vhmer (see Aristnlacliia gigat). 



in a warm greenhouse. Also by division where the 

 plants have rhizomes. 



Soil. Two parts of peat and one part each of 

 loam and mortar rubbish. None of the plants 

 require much soil. 



Other Cultural Points. Pellasas require moisture 

 all the year round, but the foliage should not be 

 wetted. They like to be kept close up to the glass, 

 but go yellow if exposed to direct sunlight. Basket 

 culture gives the exposure they enjoy. The chief 

 insect enemy is thrips, for which fumigate. Forms 

 with leathery fronds may be sponged.
