Acronychia 



( 13) 



Actinella 



50'), prickly trunks. A warm greenhouse is needed, 

 and a rich sandy loam, with plenty of water at 

 all times. Propagation is by suckers. 



Principal Species : 



sclerocarpa (hard fruited) (syns. aculeata and 

 Coco.s fusiformis). 



Other Species :

ACRONYCHIA. 



A greenhouse evergreen shrub (iiril. Rutacere), 

 with a Kue-like appearance. Cunninghamii, 7', 

 needs ordinary greenhouse treatment. Propaga- 

 tion is by cuttings, taken in July, and placed in 

 sand in a close frame. 



ACROPHYLLUM. 



Dwarf greenhouse shrubs (ord. Saxifragacere), 

 propagated by cuttings of the half-ripened shoots, 

 placed in a cool house, and covered with a bell- 

 glass ; they thrive in fibrous peat two - thirds, 

 loam one-third, and a little sand. Thorough 

 drainage is essential. 



Only Species : 



venusinii, li'. My., pk., wh. (syn. verticillatu'n). 



ACROSTICHUM. 



Description. A genus of almost wholly tropical 

 Ferns (uril. Filices), showing great variation in the 

 size of the plants and cutting of the fronds. In- 

 cluding Aconiopteris, Chrysodium, Egenoltia. Ela- 

 phoglossum, Gymnopteris, Hymenolepis, Olfersia, 

 Photinopteris, Polybotrya, Rhipidopteris, Soro- 

 manes, StenochUcna, and Stenosemia. 



Propagation. By spores, and division of the 

 rhizomes in some cases. 



Soil. Peat two-thirds, loam one-third, with 

 sand, sphagnum, and charcoal. 



Other Cultural Points. Plenty of water at all 

 times. Stove temperature, except in a few cases.
