- Circular or ring-shaped: as, a circinate eruption: specifically, in botany, applied to that mode of vernation or foliation in which the leaf is rolled up on its axis from the apex toward the base, like a shepherd's crook, as in the fronds of ferns and the leaves of the sundew; but the term is also sometimes used when the coil simply forms a ring.
- To make a circle (upon) with a pair of compasses.

Planchon  figures and describes a flower of _Drosera intermedia_ that had passed into a chloranthic condition, excepting the calyx, which was unchanged; the petals, like the valves of the ovary, were provided with stipules, and were circinate in vernation.
The stamens presented different degrees of development; in some cases they were fully formed, the anther-lobes open, and the pollen exposed; while in other instances the filaments were involute or circinate, just as the ordinary stamens are in the unexpanded flower-bud.
Seborrh [oe] a corporis differs in a measure, in its symptoms, from seborrh [oe] a of the scalp and is usually illustrative of the variety known as eczema seborrhoicum; it occurs as one or several irregular or circinate, slightly hyperæmic or moderately inflammatory patches, covered with dirty or grayish-looking greasy scales or crusts, usually moderate in quantity, and upon removal are found to have projections into the sebaceous ducts.
#When is a patch of eruption said to be circinate?
The _annular syphiloderm_ (_circinate syphiloderm_) is observed usually in association with the large-papular eruption, and consists of several or more variously sized, ring-like lesions, with a distinctly elevated solid ridge or wall peripherally and a more or less flattened centre.
Several closely-lying lesions may coalesce and a large, irregular patch be formed; some of the patches, also, may be more or less circinate, the central portion having, in a measure or completely, disappeared.

Far removed from green fields and leafy woods, they may, for instance, enjoy their leisure mornings in watching one of the most beautiful phenomena of vegetable development -- the evolution of the circinate fronds of the fern; a plant in every respect associated with elegance and beauty.
As in the ferns, the venation of its fronds is circinate, or scroll-like, -- they have in several respects a resembling structure, -- in at least one recent species they have a nearly identical form; and fronds of this fern-like type seem to have been comparatively common during the times of the Oolite.
