INFRUCTESCENCE pendent; berries red, obovoid, 6-7 mm long, 4 mm wide. Figs. 179, 181, and 184.

Anthurium seleri is known primarily from a relatively small geographic area ranging from eastern Mexico (central Chiapas) to adjacent areas of west central Guatemala in the Department of Huehuetenango at elevations from 700 to 1,900 m. The species has also rarely been collected in southern Oaxaca in the Sierra Madre del Sur, and while these appear to be outlying populations, both regions probably consist of vegetation that is "bosque pino-encino" on the Mexican vegetation maps, which arc generally quite arid. Plants are usually found growing on rocks or on steep cliffs in shaded canyons but have also been found in open almost deforested areas.
The species is a member of section Belolonchium and is recognized by its coriaceous blades, which are either oblong or narrowly triangular with usually little or no development of posterior lobes or with the posterior lobes directed outward almost at a 90° angle from the midrib. An extreme development of the posterior lobes is found in some collections from the northern and western part of the range of the species and a few collections such as Car/son 1523, Reko 6203, and MacDougall 686 have posterior lobes of the blade almost as long as the anterior lobe. An interesting feature exhibited by A. seleri is that while most collections dry matte and greenish, some collections, such as Croat 46505, dried brown with the surfaces glossy. Since no other differences were apparent it is assumed that these differences were a matter of differences in drying. Anthurium seleri collections with well developed posterior lobes can be confused with collections of A. berriozabalense. See the discussion following that species for ways of distinguishing the two species. The designated type of A. andresloviense (MacDougall 384) represents a mixed collection. Specimens from MEXU, numbers 59608 and 59838 correspond to the type description and to the photograph, respectively, presented by Matuda. Another MacDougall collection of 384 has been assigned the number 384A. It is actually A. ovandense. As mentioned in the introductory paragraph, MacDougall had often recollected what he believed to be the same plants again; when he did, he had the unusual practice of assigning them the same number as he did the first time he collected the plant. In this case the plants he re-coDccted were in fact of some other species, even though they both have similar leaves and were both collected at San Andres Lovene.
