“1. overlapping as the tiles on a roof; 2. in aestivation, used of a calyx or corolla where one piece must be wholly internal and one wholly external, or overlapping at the edge only = syn. imbricative [imbricativus,-a,-um (adj.A)]” (Jackson); see aestivation.

imbricativus,-a,-um (adj.A): “overlapping at the edge only; a term of aestivation” (Lindley); see aestivation.

- [lichen] thallus fuscescens squamoso-imbricatus, squamis saepius adscendentibus, aggregatis, margine crenatis (Nyl.), the thallus rather brownish-black, squamose-imbricate [i.e. with overlapping scales], with the scales more often ascending, aggregated, crenate on the margin.

NOTE: the moss genus Imbribryum derives from 'imbrex,-icis' ‘tile,’ in reference to the imbricated leaves, not from imber, gen. sg. imbris, 'rain.'

NOTE: in aestivation, q.v.: “When the parts overlap, the aestivation may be simply imbricate (aestivatio imbricata), the parts overlapping parallelly at the margins; quincuncial (quincuncialis; quincuncialiter imbricata) when of five parts two have their margins both inside, two with margins both outside, one with one margin inside and the other outside” (Stearn).

Tinia imbricata [L. ‘appressed and overlapping’] “a dermatomycosis in the South Pacific characterized by scattered, concentrically arranged rings of papulosquamous patches caused by Trichophyton concentricum Blanchard” (S&D); see tinea,-ae (s.f.I).
