H. violacea. — A curious species from Guiana. It produces 

 its solitary violet-coloured flowers at different times of the 

 year, and keeps in bloom four or five weeks. It has been 

 called Zygopetalum and Pescatoria. 



H. Wailesiana. — This is a very elegant little species, with 

 dark evergreen leaves. The flowers are of moderate size ; 

 sepals and petals white ; lip white, stained along the centre 

 with violet ; it blooms during the autumn months, lasting long 

 in perfection. Native of Brazil. It is sometimes included in 

 Zygopetalum, and has also been referred to Warrea. 



H. Wallisii. — In general appearance this superb species 

 resembles H. cerina, but the flowers are much larger ; the 

 gi'ound colour is a rich cream, and the sepals and petals are 

 tipped with bluish violet, the base of the column being dark 

 violet. It is a fine addition to this beautiful genus, requiring 

 somewhat cool treatment. It is also known by the names of 

 Zygopetalum Wallisii and Pescatoria Wallisii. Native of 

 Ecuador. 



lONOPSIS. 



I. paniculatus. — A charming small free-flowering Orchid, 

 and one that ought to be in every collection. The leaves are 

 six inches high, and proceed from very small pseudobulbs. 

 The flower spikes, which are branching, proceed from the 

 axils of the leaves, and are about ten inches long, the blossoms 

 being of a pretty blush white, pencilled with light rose, and 

 produced twice a year. The plant succeeds best on a 

 block, with a Httle live sphagnum moss round the roots, 

 which require to be kept moist nearly all the year round. I 

 have found it do well in the coolest house suspended near the 

 glass, where it continues in bloom for several weeks at a time. 

 This is a difficult plant to grow, for we seldom see it doing 

 well. I often find it flower itself to death.
