Pete,
I think that Brs longissima is now properly known as Brs arcuigera. And
I am pretty sure that it is the larger of the two. -- Mark

Which Brassia species produces the largest spidery flowers? Longissima or
gireoudiana?

Some say it's gireoudiana and some say longissima? I have a gireoudiana
that
is spiking for me for the first time and this plant gets really HUGE fast.
It was a small seedling two years ago and now is a big specimen size
plant.

I have a longissma hybrid which is actually 75% longissima and 25%
gireoudiana and the blooms were quite long (about 12 inches from top to
bottom, if I remember correctly) but the plant is much smaller in size.
The
bulbs are much much smaller and flat with only one leaf or two to each
bulb
which I guess is from longissima because gireoudiana has big bulbous bulbs
and 4 large leaves to each bulb.

Thanks in advance!

Pete
