  Supervolute vernation vs. convolute
From: Don Bittel <donbit121 at hotmail.com> on 2010.01.20 at 21:03:53(20506)
Steve, etc.,

     I think these drawings do make sense of this. Philodendrons would be convolute, with a newly forming leaf inside of the opening leaf. Anthuriums would be supervolute, since they don't have that leaf inside the opening leaf. Antway, it is a fine distinction, and not that important for the average grower.

    But I have always watched out the involute anthuriums, the pachyneuriums, since they are not all birdnest types, and they usually breed with each other. I've made many crosses with heart shaped leaves crossed with linear leaved rosette types. I have had watermaliense cross with convolute/supervolute types like pedato-radiatum and dressleri. The leaves come out with a mix of involute and convolute. But I have never had a birdnest type cross outside of the pachynerium section, with a convolute type.

    So, I would guess that 99.999 percent of the anthurium 'hookeri' plants sold anywhere are definitely not hybrids of the true hookeri, since I doubt it could ever cross with pachyneriums. I hope to try some of these anyway, when my hookeri starts to flower.
    Thanks for starting this confusing topic, Steve. It's been fun!

Dear Don and All,

Aloha.

According to recent posts and the literature about Anthurium section Pachyneurium, all(?) of the birdnest forms, except Anthurium hookeri, are Pachyneurium with involute vernation. I have this birdnest form Anthurium...photo files attached, that has supervolute vernation. It has very spicy, fragrant inflorescences. There is a long, naked stipe. Note the peduncle, old spathe attachment area, naked stipe, and inflorescence. Does anyone else grow this thing and does anyone have a name or data?

Aloha,

Leland
