DESCRIPTIVE LIST OF NEW PLANTS. 
“ From what I observed of the nature and habits of this most 
interesting plant, I conclude that it cannot and does not exist in 
any of the rivers, where the immense rise and fall of twenty feet 
would leave it dry during many months of the year, especially 
in the season when there is no rain. The lagoons being subject 
to little variation in the height of their waters, are the places 
where it grows in all its beauty and grandeur. The Victoria ap¬ 
pears to delight in parts of the lake fully exposed to the sun, and 
I observed that it did not exist where the trees overshadowed the 
margins.” 
The high interest attached to the species has led us into this 
rather lengthy extract, and we are obliged to pass much other 
scientific matter, which, together with four excellent plates, illus¬ 
trate the subject, forming a complete monograph of the genus. 
There are now two living specimens at the Royal Botanical 
Gardens at Kew, resulting from Mr. Bridge’s seed, which we trust 
may reward the management by the production of flowers in the 
ensuing season. 
Orchidaceje. —Gynandria Monandria . 
Dendrobium ( Onychium ) triadenium (Bindley). A lovely plant, 
with the habit of I), crumenatum , but with a very close racemose 
panicle of flowers, transparent, about as large as in I). aduncum , 
nearly white, with a tinge of rose, a violet spot on the end of the 
petals and lips, and a three-lobed yellow tubercle in the middle 
of the latter. From what part of the East Indies it has been 
procured is uncertain, but, as the focus of the Dendrobiums with 
a thickened base to their stems is the Indian Archipelago, it is 
probable that this has been derived from that quarter. The three 
yellow knobs of the lip, the close inflorescence, and the deeply- 
lobed, almost quadrangular petals, distinctly mark the species.—
