ABSTRACT
Vandeae, which includes many of the most magnificent productions of our hothouses, but like the Epidendreae has no British representative. The pollen consists of waxy masses, as in the two last tribes, and each ball of pollen is furnished with a caudicle, which becomes, at an early period of growth, united to the rostellum. The caudicle is seldom attached directly to the viscid disc, as in most of the Ophreae, but to the upper and posterior surface of the rostellum; and this part is removed by insects, together with the disc and pollen-masses. In Phalaenopsis grandiflora and amabilis the stigma is shallow and the pedicel of the rostellum long. Some compensating action is therefore requisite, which, differently from that in Maxillaria ornithorhyncha is effected by elasticity. In the structure of the column in the Vandeae contains the filament, the upper pistil and the two lower confluent pistils.
