Preliminary palynological study on Adesmia species (Fabaceae) from northwestern Argentina
The pollen morphology of seven species of the genus Adesmia (Fabaceae, Papilionoideae) that inhabit the mountainous region of northwest argentine was analyzed: A. cordobensis var cordobensis Burkart, A. incana Voguel var. incana , A. muricata var. dentata (Lag.) Benth, A. cytisoides Griseb . , A. inflexa Griseb., A. trijuga Gillies ex Hook. & Arn, A. schickendanzii Griseb. Samples were taken from fresh material and were processed according to conventional techniques for acetolyzed and non-acetolyzed pollen. Pictures were taken with an optical microscope and a scanning electron microscope. These grains are isopolar, radi - ally symmetric, tricolporate, microreticulate and heterobrochate. In acetolyzed material they are of medium size, prolate to prolate-spheroidal. In non-acetolyzed material they are small, oblate spheroidal with wide colpi in the equatorial plane, and sharp ends. Only in the case of A. schickendanzii the non-acetolyzed grain is medium size, prolate, with narrow colpi (4-5 ?m) in relation to other species, and the endoapertures are lolongate, but not as prominent as in the others. With scanning electron microscope the presence of smooth margin or with few microperforations in A. cordobensis, var. cordobensis, A. muricata var . dentata , A. cyti - soides y A. incana var . incana , A. cytisoides and A. incana is confirmed. In A. trijuga margin is densely microperforated, while A. inflexa lacks of margin and the irregular border of the colpi is observed. On the basis of the observations made, a key was developed to identify the species studied. The statistical analysis allowed to establish the differences that support their taxonomic classification.

The pollen morphology of seven species of the genus Adesmia (Fabaceae, Papilionoideae) that inhabit the mountainous region of northwest argentine was analyzed: A. cordobensis var cordobensis Burkart, A. incana Voguel var. incana , A. muricata var. dentata (Lag.)

Se analizó la morfología polínica de siete especies del género Adesmia (Faba - ceae, Papilionoideae) que habitan la región montañosa del noroeste argentino: A. cordobensis var. cordobensis Burkart, A. incana Vogel var. incana , A. muricata var. dentata (Lag.) Benth, A. cytisoides Griseb., A. inflexa Griseb., A. trijuga Gillies ex Hook. & Arn, A. schickendanzii Griseb . Las muestras provienen de material fresco y fueron procesadas según las técnicas convencionales para polen acetolizado y no acetolizado. Se tomaron fotos con microscopio óptico y microscopio electrónico de barrido. Los granos son isopolares, radiosimétricos, tricol - porados, microrreticulados, heterobrocados. En material acetolizado son de tamaño mediano, prolatos a prolato-esferoidales. En material no acetolizado son pequeños, oblatos esferoidales, colpos anchos a nivel del ecuador, con extremos agudos. Solo en A. schickendanzii el grano no acetolizado es mediano, prolato, los colpos son angostos (4-5 ?m) en relación con las otras especies y las endoaperturas son lolongadas y no se ven prominentes como en las demás. Con microscopio electrónico de barrido se corrobora la presencia de margen liso o con es - casas microperforaciones en A. cordobensis var . cordobensis , A. muricata var . dentata , A. cytisoides y A. incana var . incana , densamente microperforado en A. trijuga , mientras que A. inflexa carece de margen y se observa el borde irregular del colpo. En base a las obser - vaciones realizadas se elaboró una clave para diferenciar las especies estudiadas. El análisis estadístico permitió establecer las diferencias que apoyan la clasificación taxónómica de las mismas.
