Cypripedium irapeanum, known as Irapeao's cypripedium or pelican orchid, is a species of orchid found in Mexico and Central America in section irapeana. It has a widespread distribution from the central Mexico states of Sinaloa and Durango south to Guatemala and Honduras.Cribb. 1993. The genus Cypripedium in Central America. Orquídea (Mexico City) 13(1–3): 205–214.Breedlove, D.E. 1986. Flora de Chiapas. Listados Florísticos de México 4: i–v, 1–246. They are found in mixed pine and oak forests on well-drained limestone slopes and in areas with volcanic and clay soil which are rich in metals. They can be found in some areas in groups of hundreds. They bloom from early June to late July. The plant is tall, 1 to 1.5 m, and is pubescent with clasping elliptic to lanceolate cauline leaves in a single stem. The showy yellow flowers are 12 cm and open from bottom to top in a raceme of one to eight flowers.The Internet Orchid Species Photo Encyclopedia The balloon-shaped lip has a fine net pattern and an open bowl with an enrolled margin. There are purple-brown spots toward the rear of the bowl. They propagate both by rhizomes and from many minute seeds that are propelled from a capsule which erupts from the inferior ovary.Ames, O. & D. S. Correll. 1952. Orchids of Guatemala. Fieldiana, Botany 26(1): i–xiii, 1–395 Some people have reported a contact dermatitis after handling these plants, and they are extremely difficult to cultivate as they rely on a symbiotic fungus for nutrients.

A DNA barcode is a short, standardised stretch of genes that works like a fingerprint — enough to tell one species from another. Below is the molecular trace Cypripedium irapeanum has left across the world's sequence archives.

07Deep time~5.05 Ma lineage
How far back this lineage goes — and how we know. Everything here is measured in Ma, short for “mega-annum”: millions of years ago. The chart reads left to right like a calendar of the Earth, from the deep past on the left to today at the right edgetop to bottom like a core drilled through the Earth, from the deep past at the top down to today at the bottom.

When this lineage existed
How to read this: the coloured strip along the bottomdown the left is the geological calendar — the standard epochs (Pliocene, Pleistocene…) every museum uses, shown so you can see which chapter of Earth's history this lineage lived in. This lineage is a young one, so the strip is zoomed in to epochs — the finer subdivisions inside a period. The orange marker is the DNA clock: DNA accumulates mutations at a roughly steady rate, so comparing this species' DNA with its relatives estimates when the lineage split off — independently of any fossil.

09Environmental DNA4 detections
Where the DNA of Cypripedium irapeanum was picked up in samples of water, soil or air — nobody saw the organism, only its DNA left behind. A trace is a clue that the species was near, not a confirmed sighting.

How to read this: each dot is one detection of this species' DNA in an environmental sample. The confidence meter weighs how many independent studies and places back up the signal — one detection in one study is a hint; many across several studies is solid. Records dated before 2008 (when eDNA methods began) are treated as likely mislabeled and left off the map.
