Tentilation. Thorough drainage is necessary for them, 

 and in potting the pots should be half filled with broken 

 crocks on which the plants should be placed in a com- 

 post made of fibrous peat, sphagnum, fine crocks and 

 sand, formed into a mound from one to three inches 

 above the top of the pot. The plant should be held in 

 place, if necessary, by means of small stakes. As the 

 plants grow they should be repotted, using the same com- 

 post with the addition of a little rotten sods and manure, 

 for the flowering sorts in particular. 



Of the more desirable and common, hence lower 

 priced, sorts are AntTiurium Andreanum, with its large, 

 dark red, leathery and corrugated recurved spathe; it is 

 easily grown and a perpetual bloomer. A. Scherzerianum, 

 with long leaves and scarlet spathe on red stems; the 

 spadix is spotted with the salmon flowers. A. B. maximum 

 is a form having much larger spathes; other forms of 

 A. Sr.herzerianum vary in the color of their spathes. 

 A. Ferrieriense (at upper part of Fig. 65), is a strong 

 grower resembling A. Andreanum, except that the 

 spathe is reddish pink with a white spadix. The spathe 

 is not recurved as in that species. There are also many 

 varieties and species of each of the above. Among the 

 foliage anthuriums the better kinds are A. crystallinum, 

 (at right of Fig. 65), with large, cordate, white veined, 

 dark green velvety leaves; A. Waroqueanum {cenier ot 

 Pig. 65), deep green, velvety, lanceolate leaves often 

 thirty inches long and eight or ten wide; and A. regale, 

 having large cordate leaves with white veins. Antliurium 

 ornatum and A. splendens are also valuable. One thing 

 that makes this genus of plants particularly desirable is 

 that, if reasonably well cared for, none of the insect 

 pests of the greenhouse trouble them. 



ALOCASIAS. 



Allied to i.nthurium is this genus of foliage plants, 

 which, when well grown, present a striking appearance,
