DBNDROBIUM. 7o 



of the Linnean Society, in the volume above quoted. It was not 

 introduced till 1862, in which year it was sent to Messrs. Low 

 and Co., by the Eev. C. Parish, under the name of Vendrobium 

 albo-viride, in reference to the greenish white tint of the flowers when 

 first expanded; but as the flowers lose the green tint in the course 

 of a few days, the name was changed by Mr. Bateman in the 

 Botanical Magazine to hedyosmum, "sweet-scented/' in reference to 

 their pleasant Wallflower fragrance, overlooking the fact that the 

 species had been previously named seabrilingue, " rough-lipped," by 

 Dr. Lindley. It usually flowers in March and April. 



D. secundum. 



Eudendrobium — Pycnostacliyce. Stems terete, 15 — 21 inches long, 

 somewhat thicker than an ordinary writing pencil. Leaves ovate-oblong, 

 3 — 4 inches long and 2 inches broad, deciduous. Racemes lateral, 

 3 — 4 inches long, produced from the uppermost joints of the leafless 

 stems. Flowers crowded, all turned towards the same side, rosy purple ; 

 sepals ovate, narrow; petals similar, but smaller; lip obovate-spathulate, 

 paler in colour than the other segments, and with an orange blotch 

 at the apex ; spur long, obtuse.

var.— niveum. 



Stems shorter than in the common form. Flowers white except the 

 orange tip of the lip.

 The only claims this Dendrobe has to a notice in this place 

 are its very distinct racemes of rose-coloured flowers, and its being 

 the typical species of an important sub-section of the genus 

 fPycnostachyceJ . It was introduced from Sumatra by Mr. W. Mac- 

 Killigin, and flowered in Mr. Tate's nursery at Sloane Square, 

 London, in 1829, it having been previously discovered by Blume in 

 Java, and by Dr. Wallich in one of the islands in the Straits of 

 Malacca. It has also been reported from North Borneo (abundant), 

 and other islands of the Sundaic group, from Lower Burmah, the 

 Malay peninsula, Cochin China, and other places ; it is thence one of 

 the most widely distributed of Dendrobes. The white-flowered variety 

 was introduced by Messrs. Maule and Sons, of Bristol. Vendrobium 

 secundum flowers in the autumn and winter months. The specific 

 name refers to the one-sided arrangement of the flowers on the rachis, 

 which, in the language of botany, are said to be secund.
