I got this in spike at the POE, and it's been open for about a week now. The last pic is without flash.
We had this discussion a few weeks ago but I need to ask again. What is your plant's leaf span and how large is the flower? The reason I ask, is that I have a Phrag that was awarded a number of yrs ago as "pearcei" but at the time there were large pearcei's and small ones (growths and flowers). Now, I feel mine is indeed richteri and not pearcei at all. Your pics of ecuadorense looks like my pearcei/richteri flower.
BTW, very nice flowering
I'd say your plant with a 3 foot spike is definitely not a pearcei / ecuadorensis, and when my richteri was at its worst (and still trying to bloom) it had a 12 inch leaf span, but spikes over 18" tall, no branches and lots of bracts with no flowers. Now its closer to 2ft in span. It has 3 or 4 growths in spike, and 2 are branching pretty good. Although the flowers are not really larger than ecuadorenis they have heavier substance and last longer so that a branched spike has had 5 or 6 flowers open at a time on it.
My ecuadorensis has produced dozens of spikes over the years and generally stop at about a foot. It's rare to see 3 good flowers on a spike at a time. This year it just produced 1 branch on a spike.
Maybe richteri is just a 4N pearcei??
