78 REPORT ON THE 



DISA. Two well-grown specimens of Disa grandiflora (the 

 " Flower of the Gods ") were shown, neither being in bloom. 

 It is the most showy of all terrestrial Orchids, and comes from 

 the watercourses on Table Mountain, South Africa. 



EPIDENDRUM. Five species and varieties only were repre- 

 sented. E. ibaguense had reedy stems and lilac trusses of 

 flower ; E. Parkinsonianum, with channelled, fleshy, glaucus 

 leaves, and large pure white flowers; E. rhizophorum, another 

 species of reed-like habit ; E. vitellinium, and its variety E. 

 vitellinum majus, having glaucus-leaved pseudo-bulbs and 

 branched spikes of pale orange-vermilion coloured blossoms. 

 All are South American or West Indian. 



ERIA. An Indian genus (allied to Dendrobium), of which 

 only one inconspicuous species, viz., E. excavata, was shown. 

 Flowers whitish, in lateral clusters, issuing from a depression in 

 the fleshy pseudo-bulbs. 



GALEANDRA. S. Devoniana alone was exhibited. It is a 

 plant of grassy or reed-like habit, from the Rio Negro, and was 

 named long ago by Lindley, in compliment to the late Duke of 

 Devonshire, a patron of the Eoyal Horticultural Society, and one 

 of the first of amateur Orchidists. The flowers are borne seven 

 or eight together in terminal nodding spikes, and are whitish, 

 veined with purple on the expanded involute lip. 



GRAMMATOPHYLLUM. The plants of this genus are known 

 popularly as the " Letter Orchids," and are from Malaysia and 

 Madagascar. The plant exhibited appeared to be an undescribed 

 species. 



HOULLETIA. A small genus from Colombia. The species 

 exhibited, H. odoratissima, bears numerous yellowish-purple 

 marked flowers of exquisite fragrance, whence the specific name. 



IONOPSIS. A small genus of Brazilian or West Indian 

 Orchids, extremely difficult of cultivation. One species grows in 

 Jamaica on the twigs of hedges and trees in full sunshine, and 

 the best success is obtained by bare-block culture in our hot- 

 houses. The kind shown was I. utricularioides. 



CATTLEYA. A well-known genus of extremely showy South 

 American plants. Twenty-seven varieties were shown, Mr. Lee's
