Cardinal's Hat, Gretchen, and Macrosphila Tulip Bulbs. 
Fig. 1. — Mature bulbs of single early tulip Cardinal's Hat, showing horizontal split across the 
back when dug. This condition is prone to occur in this and some other varieties on new ground. 
Fig. 2. — Variation in the size of flowering bulbs in the same variety as shown in Figure 1. There 
is shown a variation of 6 to 13 centimeters. All of the bulbs flowered the current year. Fig. 
3.— Droppers of Darwin tulip Gretchen. The clumps are shown as dug from 5-centimeter bulbs 
planted 35 to the row and dug at one year. Fig. 4.— Droppers in single late tulip Macrosphila 
left undug until the second year. It will be seen that there are in some cases two droppers to 
the same or different levels. Dropping occurred in both seasons.
