Salvia meera, S. rogersiana, S. santanae and S. concolor var. iltisii (Lamiaceae), three new species and a variety from Jalisco, Mexico

Abstract

We describe and illustrate 4 new taxa of Salvia L. from Jalisco, Mexico. Three of them were tentatively proposed as new species in the book Flora de Manantlan . These taxa are endemic to the state of Jalisco. Salvia concolor subsp. iltisii J. G. Gonzalez differs from typical populations of S. concolor Lamb. ex Benth. in having thinner and deeply cordate leaves, floral bracts 5-6 mm long, yellowish green calyces, up to 15 mm long at fructification, and with the upper lip entire. Salvia meera Ramamoorthy ex J. G. Gonzalez is related to sect. Tubiflorae Epling, its long and narrow leaves and white large corollas make this species unique. Salvia rogersiana Ramamoorthy ex J. G. Gonzalez belongs to sect. Briquetia Epling, it is distinguished by its short and compact racemes, short calyces (less than 10 mm long), 2-flowered verticillasters, and corolla tubes up to 15 mm long. Salvia santanae Ramamoorthy ex J. G. Gonzalez fits well into sect. Angulatae (Epling) Epling and is closely related to Salvia longispicata M. Martens & Galeotti ; it differs from the latter in having persistent floral bracts, 2 or 4 (rarely 10) flowered verticillasters and, larger floral characters.
