| description | The terminal shape of the leaf was found to be correlated with other morphological features and with flower colour in the group of Lepanthes with black sheaths from Mexico and northern Central America. Plants with rounded-acute leaf tips, and the appendix inconspicuous and either with a solid portion less than 0.1 mm long or reduced to a tuft of hairs include Lepanthes nigriscapa R. E. Schult. & G. W. Dillon, L. quetzalensis Luer & Béhar and L. scopula Schltr.; L. inaequiloba Ames & C. Schweinf. has similar leaves but lacks entirely an appendix. Lepanthes nigriscapa is known only from the type material and is distinguished by a total absence of a solid appendix as well as by its divergent lateral sepals. Plants with acuminate leaves and prominent hairy appendix were first described by A. Richard and Galeotti as Pleurothallis disticha and later tranferred to Lepanthes by Garay and R. E. Schultes. Lepanthes oestlundiana R. E. Schult. & G. W. Dillon and L. pristidis Rchb. f. are best treated as synonyms of L. disticha. Material reported as Lepanthes inaequiloba Ames & C. Schweinf. from Belize and as L. turialvae Rchb.f. from Guatemala is all referable to L. disticha. Another species with acuminate leaves and black sheaths, Lepanthes hondurensis Ames, apparently endemic to Honduras, is closely related to L. disticha, but differs in having the lobes of the petals subequal, broadly elliptic or rounded, and a glabrous appendix. Typification, synonymy and a key to the species are included. |

En este trabajo se encontró que en las especies de Lepanthes con vainas negras de México y el norte de Centroamérica la forma del ápice de la hoja está correlacionada con otras características morfológicas y con el color de las flores. Lepanthes nigriscapa R. E. Schult. & G. W. Dillon, L. quetzalensis Luer & Béhar y L. scopula Schltr. presentan el ápice de la hoja redondeado-agudo y el apéndice del labelo poco evidente, ya sea con una porción sólida de menos de 0.1 mm de largo o reducido a un mechón de pelos, mientras que L. inaequiloba Ames & C. Schweinf. tiene hojas similares pero carece completamente del apéndice. Lepanthes nigriscapa es conocido solamente del tipo y se distingue por la total ausencia de un apéndice sólido y los sépalos laterales muy divergentes. Plantas con hojas acuminadas y un apéndice prominente y piloso fueron descritas por A. Richard y Galeotti como Pleurothallis disticha, concepto posteriormente transferido a Lepanthes por Garay y R. E. Schultes. Lepanthes oestlundiana R. E. Schult. & G. W. Dillon y Lepanthes pristidis Rchb. f. se consideran aquí como sinónimos de L. disticha. Material de Belice citado como Lepanthes inaequiloba Ames & C. Schweinf. y de Guatemala como L. turialvae Rchb. f., es referido a L. disticha. Otra especie con hojas acuminadas y vainas negras, Lepanthes hondurensis Ames, aparentemente endémica de Honduras, está cercanamente relacionada con L. disticha pero difiere en los lóbulos de los pétalos subiguales, ampliamente elípticos o redondeados y el apéndice glabro. Se presenta la tipificación y la sinonimia de las especies y se incluye una clave para su identificación.
