Ruellia saccata, a new species of Acanthaceae from Bolivia


Schmidt-Lebuhn, A N; Tripp, E A (2009). Ruellia saccata, a new species of Acanthaceae from Bolivia. Novon, 19(4):515-519.

Abstract

Ruellia saccata Schmidt-Lebuhn & E. Tripp, a new species of Acanthaceae from Beni, Bolivia, with a highly distinctive corolla morphology, is described as new to science. The novelty resembles and is related to R. brevifolia (Pohl) C. Ezcurra, but differs in the presence of a pronounced corolla pouch, a longer corolla with a narrower orifice, and a spreading to procumbent habit. Its differences from and similarities to other species in the genus are also discussed, and an updated key to the red-flowered Bolivian species of Ruellia L. is presented.

Resumen
Ruellia saccata Schmidt-Lebuhn & E. Tripp, una nueva especie de Acanthaceae de Beni, Bolivia, que tiene una corola morfológicamente muy distintiva, es descrita como nueva para la ciencia. La nueva especie se asemeja y está relacionada a R. brevifolia (Pohl) C. Ezcurra, pero se distingue por tener una corola más larga con un orificio más estrecho y una bolsa pronunciada en la misma, así como por presentar un hábito extendido y procumbente. Las diferencias y semejanzas de la nueva especie a otras en el género también son discutidas, y una clave actualizada para las especies bolivianas de Ruellia L. de flores rojas es presentada.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
