Bifrenaria tyrianthina

[Rosim_in_BR]

Bifrenaria tyrianthina is a rupicolous, or sometimes epiphytic, orchid native of the Brazilian States of Bahia and Minas Gerais where it can be found up until 1800meters above the sea level. It is very similar to Bifrenaria harrisoniae, the difference being the size of the calcar (much longer in tyrianthina).

Bifrenaria tyrianthina, you mean!
Just kidding! I love this soft color! "That" Bifr tyrianthina (dark magenta) is forming spikes now, soon after blooming I'll cut it!
I know you've noticed, but for knowledge of our friends in the Board:
there are other differences, apart from the spur, comparing with Bifr harrisoniae: the longer, rigid and erect spikes; the flowers above/almost above the leaves level; the more rigid and erect leaves; the perfume, not as good as in harrisoniae (for me the tyrianthina perfume is like "old flowers" or something)

Did I see a bifoliate pbulb in your plant? I never saw a bifoliate pbulb in a Bifr harrisoniae, only in tyrianthinas... may be it is another difference!

Ahahah! I was thinking of the Alliance Bifrenaria belongs to and automatically wrote Maxillaria! Thanks for correcting me, Fred, and thanks for the complementary info on the differences too!
Yes, the leading p-bulb is bifoliate!

Do you know if this grows along streams as a lithophyte or if it grows dryer, like the rupicolous Laelias. I've been trying to figure this one out for years. It keeps growing but doesn't want to bloom.

Wow, really really pretty. Love the shape and colour and never seen one like that.

It is a montane plant, K_o_o_g, it grows inland (Minas Gerais) as rupicolous in very bright places, often in full sun, in the areas known as 'campos rupestres' or rupicolous fields, (no trees in these areas, only small vegetation), where two distinct seasons are predominant, one hot and rainy and another dry and cool.

Rosim, Thank you. Does this info generally apply to Laelia lucasiana and fournieri also?
