3. ANTHRACNOSE. (c VLINDROSPORIUM CHRYSAN- 

 THEMl) 



In this disease large, brownish black blotches ap- 

 pear on the leaves, variable in size — one-fourth to 

 two inches in diameter — shape, and position. The 

 spots embrace both sides of the leaves, sapping them 

 and causing them to turn yellow. 



Treatment. Spray with Bordeaux, or ammoniacal 

 solution of Copper CarVjonate. Pick and burn all 

 blighted leaves. 



Take cuttings from healthy stock. 



4. LEAF SPOTS 



In Septoria Chrysanthemi the disease appears as 

 small brown spots which rapidly increase in size until 

 the leaf tissue dies and the foliage drops oflf. In 

 badly diseased plants nearly all the leaves wither and 

 fall away. 



A new leaf-spot (phyllosticta) is reported which 

 causes circular spots with a purplish border. 



Trcaliuciii. Same as for Anthracnose. 



Choice Aralias 



In Great Britain these fine table and decorative 

 plants are much favored and largely grown. They 

 suggest themselves as having an equally good future 

 on this continent. For daintiness, modest grace, and 

 general adaptability to any scheme of table work, 

 the small-leaved varieties are hard to beat, while the 

 medium or larger specimens of all varieties are in- 

 valuable as outstanding plants in mixed groupings, 

 or as single subjects for conservatory or entrance 

 hall. J3ut in all cases the plants must be symmetri- 

 cal; to secure this they require delicate handling, and 

 a few varieties need special individual treatment both 

 in regard to cultivation and propagation. 



A. filicifolia is a beautiful fresh green variety, and 

 from small cuttings makes a neat plant. Its ten- 

 dency to rankness of growth quickly spoils it for 

 table, but as it roots freely, a good supply may always 

 be had in readiness. It has a preference for a cold 

 bottom stage in a warm house. A. Chabrierii is not 

 of much service for table, but as a medium specimen 

 is a distinct looking plant and wears well. Tops 

 only of this variety should be taken as cuttings; 

 side slips never make perfect plants. A. elegantis- 

 sima is a general favorite; its deep colored serrated 

 foliage shows up finely on a light setting. As dainty 

 dot plants, A. Veitchii gracillima, and the new Hands- 

 worthensis are ideal in small pots. These three do 

 best grafted on A. reticulata either as tops or if great 

 quantities are in demand as single eyes, which make 

 nice plants in aliotit eighteen months. When healed 

 off the to])s of reticulata may be stryck again for 

 stock. 



A. leptophylla, A. Kerchoviana, and A. regina, as 

 distinct from the others mentioned, will stand cooler 

 treatment. They root fairly well, but are best 

 grafted, using A. Guilfoylci as stock for which these 

 varieties have a special affinity. A. pulchra is a 

 large foliage variety often seen in a neglected condi- 

 tion in cool conservatories or botanic gardens, but is 

 really a grand plant when grown freely and kept 

 straight. As a change or combined with tlio usual 



palms for decorative work on a large scale, it has a 

 fine effect, its fresli, glossy leaves show up splendidly 

 under electric light. 



Old long-stemmed plants, stripjjed and laid down 

 in a moist corner, produce quantities of nice cuttings 

 which root freely. Aralias should constantly be 

 turned round and though they like a light position, 

 a rather heavy shade (not permanent) is necessary 

 on hot days; this is especially true of elegantissima. 

 They should never suffer check either of sudden 

 changes in temperature or ruthless disturbance of 

 the roots in potting. A careful watering also should 

 be the rule especially in winter. Good turfy loam 

 with one-third leaf mold suits most varieties, but 

 the elegantissima section favor a lighter soil; leaf 

 mould and peat in equal proportions with loam one- 

 third. Where cjuantities are grown separate houses 

 are an advantage. They usually command a ready 

 sale at a paying price. In any case it is very handy 

 to keep a few of tliese most graceful subjects for 

 choice tal)le, decorative, or exhibition effects.
