1949 RYERSON LIST NUMBER SEVENTEEN = SEEDLINGS IN FLASKS Page 5 
It's been a long time since I offered any kind of flasks except 250ce 
transplants. When seedlings are shifted to fresh agar at exactly the right 
stage, they literally jump ahead in size and root growth. 
But the following four crosses in 500cce flasks "got away from me". The 300 to 
500 seedlings in each are big enough to shift to community pots = much too big 
to shift to fresh flasks ~ and while they are crowded, all are healthy and 
vigorous looking. So here's your opportunity to have an abundance of fine seed- 
lings for the price usually paid for 250co flasks. ere 
WHILE THEY LAST 
500ee Flasks (300 or more seedlings in each)....eper flask.....0$10.00 
#20=-F LC PRINCESS MARGARET X LC LUDGATE = Both parents exceedlingly large, 
brilliant and showy. Princess Margaret has fostered many outstanding new hybric, 
including Le Geo. Baldwin, Le Oliver Lines, Le Ludgate, Le American Security. 
q#oT-F Den. Phalaenopsis, Dixon strain X Self = Earlier flaskings all sold 
rapidly, at fancy prices. Now, here's your chance to get quantities of these 
darkest, most vividly crimson-purple spray=type dendrobs for practically a 
songe Long lasting blooms for Autumn. Many seedlings bloom in two to three years. 
#572-F C. DECEMBER SNOW X C. ANGELINA ~ Extra fine PURE WHITE blooms for 
Winter through Early Spring. 
#595-F C. TRIMOS "DELICATE" X BLC MALVERN - An excellent, deep, brilliant 
yellow - as this Malvern was = on the delicately tinted Trimos, can be expected 
to turn out a good percentage of perfect YELLOWS with showy crimson lips. These 
seedlings very vigorous. Should be largely Winter blooming. 

WHILE THEY LAST per flask 
250ce "Transplants" (50 or more husky seedlings in each)..eceeeoe+ $10.00 
#23-F C. BOWRINGIANA X DEN. PHALAENOPSIS, DIXON = This bi-generic cross which 
(to my knowledge ) has never been made before, is offered as a novelty. The 
eventual result is anybody's guess. The grower who likes to experiment with 
oddities, should enjoy watching the development of these Catti-Dendrobs ! 
#24=F VANDA DENISONIANA VAR HEBRIACUM X V. SANDERIANA = Another Vanda 
Sanderiana cross for those who cannot resist this most spectacular of vandas. 
(See Page 19). Denisoniana was 2s-inch sulphur yellow, marked bright orange. 
#e25-F VANDA TATSERI (V. Sanderiana X V. Tricolor) - Vigorously growing 
hybrid. Tricolor was creamy white, splashed with crimson-purple. An intensely 
fragrant and showy species. 
(Qne of each of the above three 250cc flasks = ALL THREE - $25.00) 
NOTE: My Special Potting Mixture will be included on request with all orders 
of flasks, as usual. RYERSON'S ORCHID FOOD = regularly $2.00 per pint, will be 
included for $1.00 per pint with an order of two or more flasks.
