Under plate 2065 of this wort I have, "when describing Collahiuvi 

 Wrayij suggested the transference of that genus to Vandece, and a 

 comparison of the strncture of its flower with that of Thecostele 

 vsupports this view. The column, with its long arras and tubular base, 

 the insertion on the latter of the lateral sepals, and the small hairy lip 

 with two basal auricles or lateral lobes (see note under the following 

 plate) are identical in the two genera. A better knowledge of the 

 pollinia from living specimens is in botb wanted, before determining 

 whether they should be retained as separate genera^ and whether 

 referred to VandecB or Epidendrece. The figure of the pollinia of 

 Thecostele Zollivgeri (alata, P. et R. f.) given in the * Transactions of 

 the Linnean Society ' (xxx. t. 29) requires confirmation. Maiugay 

 (who regards this as a form of qtiinqiiefida) describes it in his manu- 

 scripts, and figures the pollinia as four, terminating a long narrow 

 strap dilated upwards and with a glandular base : hence truly 

 Vandeous.— J. D. H.
