Anthurium andicola is endemic to Mexico, at 1,000 to 2,500 m elevation, occurring in both the Sierra Madre Oriental where it ranges from central Vera Cruz to northern Oaxaca and in the Sierra Madre del Sur south of Oaxaca City. One collection by MacDougall supposedly from La Gloria on the Chiapas-Oaxaca border is worthy of mention regarding its range and elevation. The only La Gloria near the border of the states of Oaxaca and Chiapas is near the Pacific Coast at an elevation of near sea level. This locality is out of place for A. andicola both geographically (being ca. 270 km east of the nearest other collecting locality) and altitudinally (all other collections from above 1,000 m). Yet the specimen differs little from collections made in the Sierra Madre del Sur (especially those from Pochutia). A collection from La Gloria (MacDougall s.n., March 5, 1953) was designated the type of A. oaxacamonticolum. A MacDougall s.n. collection from La Gloria was studied that bears the date "Mar./ 53" (MEXU 110308) but it is uncertain whether this is the type because the type description describes a plant with larger leaves and inflorescences.
Anthurium andicola is recognized by its usually ovate, reniform or ovate-triangular leaves with prominently raised tertiary venation (especially on drying), and D-shaped or broadly sulcate petiole with sharp margins and green to dark violet-purple spadix. Both the petiole and the lower leaf blade surface are often covered with a thin waxy bloom. The species is among the most variable in Mexico and even within a single population variation in leaf shape can be great, varying from conspicuously lobed at the base to not at all lobed. Plants from central Vera Cruz in the type locality are uniformly ovate to broadly ovate with rounded lobes and an arcuate to parabolic or horse-shoe shaped sinus. Further south at the type locality of A. macdougallii the posterior lobes are often directed inward with the sinus almost reniform. The same variation occurs in the Sierra Madre del Sur but leaves there are often more diminutive with less pronounced posterior lobes and more frequently an arcuate sinus. Sometimes the anterior lobe is considerably reduced and almost rounded at the apex such as in the case of Reko 6064 from Pochutia (Oaxaca) and MacDougall s.n. from La Gloria (Chiapas), which is the type of A. oaxacamonticolum. It has been placed in section Belolonchium.
The species is not easily confused with any other although some specimens, especially those with poorly developed posterior lobes from the southern cordillera, are similar to those of
A. chamulense.
One specimen collected at an unknown locality in the Sierra de Oaxaca (September, 1961) and assigned a Matuda collecting number (38275) is sterile but probably is also A. andicola. This collection bears the herbarium name A. glaucotitanioides Matuda. The blade is thinner than most and does not have the pronounced venation of typical A. andicola.
The herbarium name A. campii A. D. Hawkes based on Camp 2762 represents a form of A. andicola not much unlike the typical form from Vera Cruz, even though it was collected relatively near the type of A macdougallii.
Matuda 38721, presumably collected near Mitia, SW of Oaxaca, has blades thinner and with less conspicuous venation than most A. andicola
collections. The region was visited recently and turned up no obvious habitat for Anthurium so he live plants could not be investigated further. They are presumably only unusually thin-leaved collections of A. andicola, since that species occurs on both the Atlantic and Pacific slopes, but no other collections have been made in the vicinity of Mitia.
