longitudinal tubercles, which, at the very base, rise into 
two erect membranes, embracing the lower part of the 
column. Column about half as long as the petals, semi- 
terete, yellow, with a bright-red mark below the stigma. 
The Anther-cases had all fallen from our plant. Pollen 
Masses obovate, waxy, with a depression at the back, 
fixed to a linear, white footstalk, having a reddish gland at 
the base. Germen linear, clavate, not twisted. 
Communicated from the Dublin College Botanic Garden, 
by J. T. Mackay, Esq. who received it, in 1825, from 
Brazil. It flowered in the month of February (1827), and 
yields so delightful a fragrance (resembling, as it appears to 
us, that of the Cowslip), as to be well worthy of cultivation 
in every stove. The whitish, membranous bractee remain 
after the flowers have fallen, and give a singular appear- 
ance to the-old scapes.
