Houlletia 



perhaps, if all be well ; but more water is nut 

 needed on that account until spring. 



E. vitellinum pure and simple flowers in autumn. 

 Its colour is not so brilliant. 



The harsh leaves warn us that both like sunshine, 

 but shading is necessary at midsummer. May and 

 June, or autumn. Mexico. 1840. Vitellinum , 

 3s. 6d. ; majus, 7s. 6d. 



Wallisi (a collector). Small, but very pretty, 

 and unlike others. Sepals and petals yellow, 

 speckled with maroon ; lips white, with dotted 

 lines of purple. Flowers at all seasons. Colombia. 

 10*. 6d. 



HoULLETIA. 



(M. Houllet, Curator of the Jardin des Plantes.) 



This small genus has only one cool representa- 

 tive. The spike rises from the base of the pseudo- 

 bulb. 



Odoratissima should be treated like an Odonto- 

 glossum, but kept somewhat drier in winter, for it 

 rests. It is curious and striking, agreeably scented ; 

 flowers large, dull red, mottled closely with lines of 

 darker hue. The lip is very singular, white, ending 

 in a broad barbed blade, of shape exactly like a 

 " Neolithic " arrow-head, attached by a slender neck.
