Wimmeria pubescens can be differentiated by its smaller leaves, 1–2.2 cm long, with 2–3 secondary veins per side running parallel to the margin and the inconspicuous tertiary veins (vs. leaves 2.5–7 cm long with penninerved venation with 4–6 secondary veins per side and conspicuous tertiary veins in  W. excoriata).</p><p>The peeling bark of this species resembles plants of  Plinia L. (1753: 516) and  Psidium L. (1753: 470). Because of that, at times it has been confused with guava trees. Seedlings of  Wimmeria excoriata have conspicuous and finely linear leaves that change progressively to obovate to oblanceolate, rarely elliptic, as the plant grows, usually when the plant exceeds approximately 30 cm high. This heteroblastic condition has been never documented in the genus before. It could be a diagnostic character for this species alone, or future studies may prove that it also occurs in the seedlings of other species of  Wimmeria .</p><p>The two populations known from Costa Rica are disjunct and both have between 6 to 10 reproductive individuals. Nothing is known about populations from Honduras and Nicaragua.</p><p>The label on A. Gamero 65 (EAP), from Honduras, mentions purple flowers, but the specimen only has fruits and no flowers can be seen. The collector may have confused the structures and treated the red fruits as purple flowers. The specimens J.A. Linares 3510 (EAP) and J.E. Jiménez 848 (CR, MO, USJ) report white flowers (Fig. 2).</p></div>	https://treatment.plazi.org/id/62223747FFF45801FF48FF20B140FD28	Public Domain	No known copyright restrictions apply.
