Abstract

Of the two short-tubed orange-yellow Puccoons of central Iowa, L. canescens is found on every remaining fragment of upland prairie. It is completely destroyed by the first cultivation, and is rapidly depleted near towns by flower-lovers looking for the first spring blossoms. On bluffs of exposed loess soil we find rather rarely L. Gmelini. When the two are side by side they are easily distinguished by the pubescence of the leaves. That of L. canescens is noticeably finer and more copious than that of L. Gmelini. Each hair of the latter also stands on a tiny colorless papilla.
