. Carnegie Institution of Washington publication. 614 STARCHES OF LILIACE^. A feature worthy of note is the marked differences shown by different genera in the relative reac- tion-intensities. Upon this basis the several genera of Liliacece examined may be grouped in three or four classes having from high to low reaction intensities, or, in other words, having low to high resistances to chemical reagents. Thus, Lilium, Fritillaria, Calochortus, Tulipa, Erylhronium, Scilla, Chionodoxa, Ornithogalum, Puschkinia, and Galtonia have, on the whole, high reaction-inten- sities; in Hyacinthus and Lach

The differences in the resistance of the starches of Brodicea to chemical reagents compared with those of Tulipece, for instance, is striking. Chart No. 186.
