Cattleya tigrina Alba

Pretty. Those are sturdy looking flowers.

The sheen on those olive green tepals is very nice. And great contrast between the green and white.

I could be wrong but isn't this C. tigrina?

Quote:

Long known as Cattleya leopoldii Verschaff. ex Lem. and before that, Cattleya guttata var. leopoldii (Verschaff. ex Lem.) Linden & Rchb.f., this orchid is still confused by many with Cattleya guttata. It is true that both have spotted flowers and a bright fuchia midlobe of the lip, but there are more differences than similarities between the two. Identifying the two will be the topic of another essay, but for now, the easiest way to tell C. tigrina and C. guttata apart is by blooming season. C. tigrina flowers in early summer from a green sheath, whereas C. guttata flowers in late summer (or early autumn) from a dried sheath.

the sheath looks green to me but my eyes could be deceiving me.

Either way, absolutely beautiful alba form!

yes i think it's tigrina

From this link here, somebody's guttata (or at least they say it is one) - appears to have flowered from both a dried sheath and a green sheath.

But - on the other hand, it's possible that their very last photo on the page is of a different plant, and is not a guttata.

I think the best bet is to go with the AOS article - as in tigrina flowers from a green sheath, and guttata flowers from a dried sheath. Although - I wouldn't be surprised if there happen to be exceptions heheh.
