This very curious plant was received by Messrs. Locldiges 

 from Mr. Schomburgk. It has the erect raceme of Houlletia 

 Brocklehurstiana, but the flowers are much smaller, form a 

 pyramidal mass, and are yellow, streaked with so much 

 deep chocolate-colour that the former is hardly seen except 

 on the lip. From the similarity in habit between these plants 

 and Maxillaria Warreana one would have thought they must 

 have belonged to the same genus, but an examination of the 

 fructification does not confirm that opinion. 



The opinion of Mr. Adolphe Brongniart concerning the 

 affinity of this genus has already been given at no. 47 of the 

 miscellaneous matter of the present volume. It is not ad- 



* So named after Mr. Houllet, a gardener, who accompanied Mr. Guil- 

 lemin upon his mission to Brazil in search of evidence concerning the culti- 

 vation of Tea.
