orow in the greatest profusion in the situation described ; 

 and though at the period of Mr. Skinner's visit they were in 

 a parched and torpid state, he was informed by a resident 

 that during the season of their flowering they scented the 

 air to an extraordinary and almost insupportable degree. 

 To this ' excess of sweets ' E. altissimum contributes a power- 

 ful odour resembling bees-wax ; but in potency it is far 

 surpassed by another unpublished species from the same 

 quarter, for which I am also indebted to the zeal and libe- 

 rality of Mr. Skinner, and which yields a perfume at once 

 delicate and powerful, and so closely resembling that of our 

 wild English primroses, that I have in consequence named 

 it ' E. primulinum.' ' 



I have also received it from Messrs. Rollissons. It is 

 very like Epid. oncidioides, Bot. Beg. t. 1623, from which 

 its long pseudo-bulbs, gigantic stature, and labellum, alone 

 distinguish it. 



62. ACACIA cultriformis. A, Cunningham, 



in Hooker's Ic. plant, ii. t. 1 70. 



This species has flowered in the collection of Messrs. 

 Rollissons, and proves a most charming conservatory plant, 

 with quantities of clusters of yellow flowers, terminating 

 branches covered with glaucous half rhomboidal leaves.

A beautiful stove epiphyte, sent from the neighbourhood 

 of Vera Cruz to the Horticultural Society by their collector, 

 Mr. Hartweg. It has pale straw-coloured flowers, about as 

 large as those of O. flexuosum, with a faint smell of prim- 

 roses. The base of the lower sepals, the lower part of the 

 lip, the column, and a line along the origin of the petals are
