Information regarding this plant is scant. A member of the section of Anthurium Semaeophyllum, it is one of only 60 species out of roughly 1000 species in the genus to fall into this group, which is comprised of the lobed-leaved anthuriums, and one of only 23 species with deeply trilobed leaves. These species include leaves that are lobed but entire with no leaflet division. Examples include A. falcatum, A. insigne, A. truncicola, A. tridigitatum and others. A. grex-Avium seems to be most closely related to A. truncicola. (information gleaned from 'The Sectional Groupings of Anthurium', Richard Sheffner and TB Croat, Aroideana Vol 6 #2, 1983 pp. 117-119)

First collected and published by Michael Madison in 1978, A. grex-Avium is endemic to Ecuador. It grows in subtropical and tropical wet montane forest at high elevations of 6200-7200 feet in the Andes as a climber. It is known in very few locales in SE Ecuador in the Province of Morona-Santiago along the western slopes, along trails from Longrono to Yaupi in the Cordillera de Cutucu, which borders the Upano valley and includes the central peaks of the Andes. A single collection was made in Peru, which has significant morphological differences from the Ecuadoran plants. Anthurium grex-Avium is on the red list as a threatened species (due to habitat loss). Madison's data was published in Selbyana, the journal of the Marie Selby Botanical Garden in Sarasota FL, Vol 2 No. 2-3, pp. 239-282 and was the first revision of the genus Anthurium since the 1800's.

A second revision was undertaken by Monica Carlson and Dr. TB Croat and published in 2007 in "Harvard Papers in Botany", Vol 12 #1,June 2007 pp. 173-234, it was further described as a climbing species having long internodes, green spadices and green fruits, cataphylls that decompose but persist into coarse stem fibers, and coriaceous leaves (which are a common characteristic of high elevation plants).

I obtained my plant this week from Ecuagenera USA in Apopka FL. When I saw it sitting there, I knew I had to try and cultivate it. Its threatened status makes it imperative that this and plants like it (for example the now- rare palms of Madagascar and Sarawak and many other plants in many tropical locales being decimated by industry) be given every chance to thrive in private collections and botanical gardens so that the species can be continued in the worst case scenario of total habitat loss.

From the information gleaned in the 3 articles above, I can infer the following when I try to grow this plant:
A/ high elevation = can tolerate cooler temps, but will still need high humidity, so perhaps best to locate near one of the water sources in the greenhouse
B/climber from subtropical and tropical wet montane forest....will need a sturdy support and ample watering of the adventitious roots as well as the ground roots, so probably daily watering in the warm/hot growing period. I will probably leave this plant in a container and locate it next to the support, so that in the event of disaster I can cut the stem and still have a rooted plant to re-grow from.

It does;t look very impressive now, having one mature leaf and another new leaf emergent, but hopefully it will thrive and turn into a beautiful specimen

I have my fingers extra crossed for this little guy's journey. Not that I don't for more common plants, but I really feel for those with habitat loss.
The trilobed leaf is pretty neat too.

I like it a lot...the name, Avium is from the Latin root for bird. It does look like a bird in flight.

I was not expecting it to me maroon-ish! I thought it would be light green! Congrats 🎉

Many anthurium leaves are maroon/red/brown when they emerge

Yes, I guess the goblin dragon leaf is a similar shade.

What people want is for them to STAY red. There are breeding programs trying to make colored anthuriums.

The color change is kind of fun, I think. It's pretty when you have mature leaves and young leaves at the same time.

The little new leaf is growing fast! And the plant is loving having been transferred to the chunky mix from the peat based mix it was in
