BULBS AND BULBILS OF ORNITHOGALUM CAUDATUM AIT

The assumption of Troll (1939), that the bulbils attached to the abaxial side of the bulb-scales of Ornithogalum caudatum are stalked axillary buds grown congenitally with the next-higher situated leaf, has been confirmed by the present morphological and anatomical investigations.

The bulbils originate at the base of the abaxial side of bulb-scales. Analysis of the vascularization showed, however, that they are connected with the enveloping bulb-scales which are therefore to be considered the actual subtending leaves.
