    Default Porroglossum echidna

    The genus Porroglossum includes 38 species restricted to Andean South America, where they range from Venezuela to Peru (Luer 1987). Ecuador is the genusís center of
    diversity with 23 species recorded (Dodson 2004). With 8 species, Colombia has the second highest species concentration.

    I find this genus very fascinating. The function of the lip is very interesting.

    The lip is hinged and has a mechanism that snaps shut when stimulated by a pollinator, thus trapping the insect to ensure that the pollinia will be removed and later transferred to the receptive surface. The lip opens after 30 minutes or so to release the insect, but also closes a night and reopens at dawn.

    At present time I have 25 species in my collection but I'm trying to get them all...

    P. echidna occurs in Venezuela and Colombia, 2500-3200m. Flower size (including the tails) 4cm. Plant size 4-5cm. I/C grower.

    The information you add to your post of lovely photos is so wonderful. Thank you for taking the time to share the information with us in addition to the photos. I love the dark, mysterious bloom. It is so interesting how it captures the pollinator like that and then lets him/her go.

    Cheers,
    BD

    A more color member of this genus than any others I have seen. I'll be looking forward to seeing your other Porrs as they come into bloom!
