Rick H. Does your inflorescence branch? A big ecuadorensis can be very difficult to tell from a poorly grown richteri. But spike branching is fairly indicative of richteri (or richteri/pearcei hybrids). My richteri when grown in bright conditions was almost the same size as my larger pearcei, and the spiked never branched. However, after a year in darker conditions the plant grew much larger, and the spikes frequently branch, and are much longer than the pearcei ever get. The flowers are not that different in size, but the coloration and markings are crisper and more distinct in richteri.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
WOW, Maybe once mine gets going I'll get the same. (*PS I posted it today*)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??
