29. Teucrium L.

Kinostemon Kudô, Melosmon Raf.

Por B.B. Klitgaard.

Arbustos,subarbustos, o hierbas perennes (rara vez anuales o bienales), frecuentementearomáticos o hediondos, glabros o pelosos, los tricomas simples. Hojasopuestas, simples o lobadas, los márgenes enteros, diversamente dentados opinnatilobados, pecioladas o sésiles. Inflorescencias cimas axilares o tirsospaniculiformes a espiciformes, las cimas frecuentemente reducidas a floressolitarias localizadas en las axilas de las hojas o en racimos o cabezuelasbracteadas. Flores bisexuales, zigomorfas, pediceladas o sésiles. Cáliz5-lobado, actinomorfo a 2-labiado; tubo frecuentemente más o menos giboso;lobos todos similares o el lobo superiordiferente a los otros 4, o los lobos superior, lateral e inferiordiferenciados como tipos distintos; cáliz fructíferoacrescente o no acrescente. Corola 5-lobada, generalmente 1-labiada conlabio inferior presente, rara vez 2-labiado, el lobo inferior mucho más grandeque los otros, generalmente cóncavo, bastante variable en color. Estambres 4,didínamos, exertos; filamentos arqueados o rectos, las tecas divaricadas,generalmente confluentes en la dehiscencia. Disco ausente (Mesoamérica) a biendesarrollado. Ovario levemente 4-lobado; lobos del estigma iguales(Mesoamérica) o desiguales. Frutos en nuececillas obovoides a oblatas osubglobosas, por lo general reticuladamente estriadas a alveoladas, pelosas oglabras, la cicatriz de abscisión 0.3-0.8 veces la longitud de la nuececilla,lateral, generalmente albuminosas. 2n = 10-104 (más frecuentemente 26 o 32). Aprox. 250spp. Subcosmopolita pero principalmente extra-tropical, con el centro dediversidad en la región mediterránea.

Las especies delNuevo Mundo pertenecen a las secciones Stachyobotrys y Teucris.Debido a que las hojas varían mucho en tamaño entre los individuos, las medidasen las descripciones de las especies fueron hechas en hojas del 1/2 del tallo.
