是 Cattleya Peckhavensis (aclandiae X schilleriana)
我的华文不太好, 用英文来解释。。。
The key distinguishing feature between aclandiae and its primary hybrid as well as schilleriana is with regards to the structural differences around the area of the side lopes as well as the part of the lip conjoining it.
The side lopes of aclandiae is much narrower and very much wide opened comapred to schilleriana and Peckhavensis.
The lip of aclandiae is often much flatter and also shorter than the other two, but the key point is the part joining the lip to the side lopes - it's much broader and shorter too.
我知道到处有很多骗子把Cattleya Peckhavensis 卖出当 Cattleya aclandiae 或则Cattleya aclandiae var nigrescens ( USD$3000 per cutting!!!-petal 颜色比较黑). 最近还有人把Cattleya Black Jack 卖为‘迷你Cattleya aclandiae'....
