q] Naked, nudum. Flowers attached immediately upon

Plantago, Orobanche, Verbascum decurrens, Heliotropium 
Indicum, Hyoscyamus niger, Phyteuma spicata. 
Branched, compound, composita, ramosa. The axis is 
divided into branches, and these branches entirely covered 
with sessile or nearly sessile flowers. Chenopodium spina- 
cifolium, Heliotropium Europzeum, Sempervivum tectorum. 
Spikeletted, spzculata. Composed of several small spikes, 
sessile or nearly so, and pressed close to the axis. Carex

Paniculated, paniculata. ‘The branches of the axis dis- 
posed like a panicle. Verbena officinalis, V. triphylla, 
Mentha rotundifolia, M. viridis. 
Fingerlike, digitata. Axis divided to the bottom: into 
several branches, not afterwards divided. Trasus digitatus,

amphibia, Bistorta major, Lavandula Tragi, Verbascum

a little beyond the spike. Acorus aromaticus.
