 possess arc grown in loo much heat, which causes grierous failures. Another great evil is the giving them 

 too much water at the roots, the consequences of which arc not found out at the time, but appear after- 

 wards. Of course there are some Orchids that require more water Hum others in their growing season:

Jtride* WilUamtii is of compact but very slow growth, sturdy in habit, and furnished with broad, 

 dark-green leaves, more than a foot in length. The spikes are produced from the axils of the two-ranked 

 leaves, on opposite sides of the plant, and are from two to three feet in length. The (lowers arc of B 

 pinkish-white colour, and are produced in May and June, continuing in perfection for three and four weeks. 



This plant resembles in its natural habit and habitat the others of its class, and requires similar treat- 

 ment to that already recommended for JcHdet mbile (Plate XL). It is difficult to propagate, there 

 having been only one young growth on it for ten years. The stems moreover do not produce roots except at 

 the base. From these causes it will always be rare, unless fresh importations arc made. Though the plant 

 has been in the country for so many years, the leafy part is not now more than a foot high, yet we have 

 never known it fail to produce two or three spikes of flowers annually. The plant would have been larger 

 were it not that it loses its lower leaves.
