    Default Catasetum (Cstm) Jumbo Pearl

    First, I must thank Ian (CatasetumIan) for his tip on how to get male flowers from this Catasetum. For the last 3 years it has been producing only female flowers ( ugh...ugh...ugly things) until I followed Ian's advice and placed the plant under the verandah roof when I noticed a spike forming. The verandah is just next to the orchid house and completely shaded from the sun.... and hey presto, male flowers, all 13 of them on a 2-foot long spike.

    Don't know why it's named Jumbo Pearl - it's obviously not pearly white, maybe a black pearl perhaps, but I'm not complaining. The colour is more like dark chocolate.

    You are welcome Yew Sung. nice flowers you got there,
    part of the name Jumbo is because this crosses is made by Jumbo Orchids from Taiwan, similar to other many "Jumbo crosses" registered. My guess here is that the name "Pearl" is used because many of the Jumbo Pearl inherited the prominent calluses from the tenebrosum, producing a marked raised structure at the center of the labellum, resembling a pearl structure. these calluses are often bright yellow in color (many thanks to the tenebrosum gene).
    However, the flower you posted lack of this particular trait and also jumbo pearl has a laterally spread lateral sepals at an acute angle. i believe it might be a cross with Jumbo Pearl and i did manage to find one very similar photo to yours in the flickr.

    Thanks Ian for your comments and observation. I believe you could be right re the ID. I went out this morning to check on the flowers with regards to the points raised by you, and comparing the pictures and the one in your link. I did find the raised callus and it is white in colour. I'm posting a picture in which the callus can be seen, a bit indistinct due to my laziness to take a proper close-up picture.

    actually i can see the callus from your first post. just that jumbo pearl usually have a more pronounce callus, sometimes a double calluses (like the tenebrosum), on the upper and lower of the depression of the labellum during a primary cross with it.

    but again when it comes to hybrid, anything is possible because of the vast possibility of genetic combination. these are my tow cents thoughts.......=D
