Utricular
Definition:
(a.) Of or pertaining to a utricle, or utriculus; containing, or furnished with, a utricle or utricles; utriculate; as, a utricular plant.
(a.) Resembling a utricle or bag, whether large or minute; -- said especially with reference to the condition of certain substances, as sulphur, selenium, etc., when condensed from the vaporous state and deposited upon cold bodies, in which case they assume the form of small globules filled with liquid.
