The genus Houlletia was founded by Brongniart on a 
Brazilian plant, discovered by M. Guillemin at Rio de Janeiro 
during his mission to Brazil in search of evidence concerning 
the cultivation of tea, and was named after M. Houllet, a 
gardener who accompanied M. Guillemin on his mission, and 
transmitted plants to the Jar din de Plantes. Singularly enough 
M. Brongniart gave no specific name to the plant he described, 
which is in all probability the II. Brochleliurstiana , Lindl. 
Sect. Orchid, t. 41 (tab. nost. 4072), of which we have native 
specimens gathered by Gardner on the Organ Mountains 
(Herb. n. 5871). Prom this, the original species II. picta , 
though coming from so distant a country, appears to differ 
very slightly, and chiefly in the more cinnamon- coloured 
larger flowers, and in the epichyle of the lip not being of a 
uniform dark violet hue but white and barred with innume- 
rable red-purple bands. The sepals and petals too are longer 
in proportion. Reichenbach, indeed, says that the flowers of 
II. picta are the smallest of the two, but this is not the case 
with our specimen. H. picta was discovered by Schlim in 
July 1st, 1877.
