collected in thousands it can only be found in dozens to-day. The fine 
Diacrium bicornutum that was the glory of some of the smaller islands 
belonging to Trinidad, is also fast disappearing through the raids of the 
collector, a remark which also applies to Oncidium Papilio. This note 
points to the possibility of the ultimate extermination of these beautiful 
plants, and we hope the Trinidad Government will follow the precedents 
set elsewhere, and take any steps necessary to prevent such a misfortune,

NOTES ON CERTAIN VARIETIES OF 
DENDROBIUM NOBILE. 
A FEW notes regarding the different named varieties of Dendrobium nobile 
may be of interest now that so many of them are in flower. The following 
are made with the flowers of the different forms collected together side by 
side for comparison, and the varieties are arranged so as to show the 
distinctive grades—from richest purple to purest white. The measurements 
are my own, and are taken from tip to tip of the petals; but, of course, the 
size of flowers will vary slightly in cultivation, in consequence of the 
different ways in which the plants are grown. 
1. D. nobile nobilius. [Flower from original plant from Sir Trevor 
Lawrence, 3} inches.] This flower exactly agrees with the drawing of the 
original plant (Orchid Album, plate 214), the colour being of the richest 
wine purple, the shape of the flower round and excellent, the petals well 
filling in the space between the sepals. Lip with deep maroon disc, 
surrounded by a band of white, with rich apical blotch of deep purple. 
Ditto. [Flowers from other sources, 4 inches.] Exactly the same in 
colour, and of grand size, the extra breadth of the flower caused by the 
petals being more elongated and not so well ue up the space between 
the sepals as in the original plant. ] 
[NotEe.—Although both these are undoubtedly D. nobile nobilius, I 
believe they originate from distinct plants. On repeated flowering I find 
the same differences, Sir Trevor Lawrence’s plant being the most pleasing 
in consequence of its perfect shape. 
2. D.nobile Sandertanum. [Flower from Sander, 2} inches.] This is 
extremely like the original nobile nobilius, but the flowers are smaller and 
the two petals overlap the sepals more than in any other variety, and thus 
give the same a very distinctive character. 
3. D.nobile elegans. {Flower from Sander, 3} inches.] | Symmetrical 
in form, richly coloured as in nobilius, but white at the base of the flower, 
petals broad overlapping the sepals, but not so much as in Sanderianum. A 
rich coloured form. 
4. D. nobile purpureum. (Flower, 3 inches.] This form flowered with
