are the Harveyas, Gerardias, Strigas, Buttonias and Cyc- 

 niums, which, together with Graderia, belong to the tribe 

 Gerardiea?, the members of which are, as a rule, more or 

 less parasitical on the roots of other plants. We have tried 

 most of the plants here mentioned at Kew, and still possess 

 plants of Buttonia and Gycnium ; but, although we man- 

 age to keep them alive, they do no good, and probably 

 never will, until we get the host-plant to grow them on. 

 Perhaps Mr. Nelson can supply the information which will 

 enable us to grow the Graderia with success. 



Porana paniculata. — English gardening papers are rec- 

 ommending " Porona paniculata'' on the strength of a 

 paragraph which appeared recently in an American paper. 



of dazzling white patches resembling snow patches in the 

 jungle." 



Neuwiedia Lindleyi. — This is an Orchid with flowers of 

 very exceptional structure. The most marked peculiarity 

 of Orchidaceae is the consolidation of the stamens and pis- 

 til into one mass, called the column, and the suppression 

 of two or one of the three anthers. But in Neuwiedia the 

 stamens are perfect, quite separate, and they surround the 

 stigma, which is as simple as that of a Lily. There is a 

 plant of the above species in flower in the tropical Orchid- 

 house at Kew. It was imported from Penang five years 

 ago and is now a tuft of Curculigo-like leaves a foot long, 

 with a central erect spike two feet high, half of it clothed

I,suspect Porana is meant, there being no such genus as 

 Porona. P. paniculata is one of nine species of a genus of 

 Convolvulacea?. They are all natives of the tropics of 

 Asia, P. paniculata being common in the jungles of India. 

 It is cultivated in botanical collections in England, where 

 it grows freely in a moist stove and produces, somewhat 

 sparingly, large-branched panicles of small, dull white 

 flowers. It would be attractive in the mass and probably 

 is a useful garden-plant in countries where it can be grown 

 out-of-doors. There is, however, a better species for the 

 garden in P. racemosa, which is grown at Kew, and which 

 is known as the Snow Creeper in India, where, according 

 to Mr. C. B. Clarke, it is " a most beautiful plant, the masses 



with yellow flowers, each an inch long and subtended by 

 a narrow green bract. The sepals and petals are as un- 

 like the ordinary Orchid as are the other parts of the flower, 

 being equal and similar, free, with the merest suggestion of 

 a lip in one of the petals. Imagine a flower of Lachenalia 

 perched on the top of a three-sided ovary, and with three 

 instead of six stamens, and one has a good idea of the 

 flower of this extraordinary Orchid. 



Hardy Ornamental Flowering Trees and Shrubs. — This 

 is the title of a little book prepared by Mr. A. D. Webster, 

 a forester, and author of several other little gardening 

 works. It is intended chiefly as a guide to horticulturists 

 in the United Kingdom, the term hardy being applied to
