Though generally leafy, a Stem may be partially naked, or even entirely so in plants destitute of leaves altogether, as the Creeping Cereus, Cactus flagelliformis, Curt. Mag. t. 17, various exotic species of Euphorbia or Spurge, and the whole genus of Stapelia. In Orobanche, it is scaly, squamosus.

With respect to mode of growth, the Stem is

Erectus, upright, as in Yellow Loosestrife, Lysimachia vulgaris. ''Engl. Bot. t.'' 761.

Procumbens, procumbent, Wood Loosestrife, L. nemorum, t. 527.

Repens, creeping, Creeping Loosestrife, L. Nummularia, t. 528, and Creeping Crowfoot, Ranunculus repens, t. 516.

Adscendens, ascending obliquely without support, as Panicum sanguinale, t. 849.

Prostratus, prostrate, or Depressus, depressed, when it lies remarkably flat,
