No, You only get the ones that say " orchid" before the genera name. Then it starts showing daylilys. If you use the alphabetical search you will find Cattleya, Dendrobium, Phaleonopsis, etc. That's fine if you know what type of orchid you're looking for. If you don't know , you would have to search the entire data base from A to Z to see them all.
Of the ones found alphabetized, only a few show "orchid" in the description, but I suppose if you see Cattleya orchid you would assume that all Cattleyas are orchids.
