C Portia #1 vs. C Portia #2
 

My "other" Portia (#2) has opened its first flowers, I'll take advantage of the latest Portia #1 flowers (that I previously had shown in the OB) to compare each other. The plant habit is the same, since the size of the flowers (the difference is visible in the photos) and perfume are different, in #1 is more reminiscent of C. labiata and predominates in the morning, in #2 is a little more citric and remains even in the afternoon
Portia #2 would be a pure C bowringiana, not a Portia?

Both are lovely flowers of a Portia, not bowringiana.

I don't know about the name, but both are beautiful! :wtg:

I agree. C. Portia's blooms look and smell like C. labiata's flowers. C. bowringiana seems to dominate for plant structure and size (the large pseudobulbs, especially the distinctive swollen base that produces tons of roots, are very much distinctive of C. bowringiana, and not C. labiata), as well as imparting vigor to C. Portia. Luckily, the C. Portias in my collection did not inherit the scent of C. bowringiana, which is not very pleasant. I have C. bowringiana also, and although the plant grows like a weed and the flowers are quite pretty, their scent, once experienced, doesn't encourage you to stick your nose up close to them a second time. Frederico, I would be quite pleased with the C. Portias you have. The flowers are stunning.

They're both beautiful!

Hi friends, thank you all!

With this information, plus what the friends from a Brazilian forum reported, it is possible to obtain some certainties and also continue with some questions (if not, what fun would it?)

1) I certainly have two hybrids - the "perfume" of “pure” C bowringiana isn’t pleasant, and this is not the case in any of my plants.

2) I certainly have two hybrids with a parent plant being C bowringiana - the appearance of plants, their growth and vigor (they actually "grow like weed” - my mother picked up a single pbulb that fell to the ground, in one of the many divisions and repoting I did, stuck it in a pot with soil - ! - and now she has an adult plant)

3) probably at least one plant is really C Portia, as it scent like C labiata and the flowers do not last long, only seven days as quoted (as C Portia flourish almost continually, one spike after other, I had not heeded this detail)

4) the other can be C Portia also (plants grown from seed can be very different from each other) or can be C Porcia (C Armstrongiae x C bowringiana) with long-lasting flowers - if the flowers will last for three weeks that I'm on it! Or C Fabingiana (C Fabia x C bowringiana), whose most famous clone is "Hibarigaoka." Or C bowringiana x ? – Only God knows!
