| + | Collomia (Greek for glue, alluding to the mucilaginous character of the wetted seeds). Polemoniaceae. In Asa Gray's late treatment, Collomia is included with Gilia, although at first kept distinct by him (Proc. Amer. Acad. Arts. & Sci. XVII, 223), and this disposition is followed here, particularly since none of the species seems to be known in the trade as Collomia. Engler & Prantl keep the genus distinct, however, ascribing to it eighteen species from western North America and Chile. Such as are cultivated will be found in this Cyclopedia under Gilia. The Collomias are annual, biennial and perennial. |
