254 ERECT FLOWERED RIGIDELLE. 
We do not know whether in its native country it attains or surpasses at 2 Meters in heigth, 
as it is the case with R. flammea, RR to Dr. Lindley; but in a cultivated state, it appears 
much more vigorous with us than its two congeners; its stem much more robust, its bern much 
more ample and firm; its flowers Cie? all are greater and of a much more bright colour.—We cannot 
say at what hour in the night they open; but from five o’clock in the morning, during the Month 
of June, that the shewed themselves (probably for the first time in Europe, in Mr. Vanhoutte’s Gar- 
dens), they where already completely spread out, and did not reclose until after midday.

rigidity, those of certain young Palm Trees. Pay A re Dre elongated, acute, ehr

CULTURE. 
The culture of Bulbous (or rather bulborhizous) Plants presents no difficulty : whence does it 
arise then that it is so neglected or rather so misunderstood? the fault is certainly not in the plants 
it must be attributed to the ignorance of horticulturists. 一 The Tigridia, the Ismene, the Ferraria» 
the Karger the Phalocallis, the Rigidella , ete., etc., are plants of the greatest interest in a 
botanical and ornamental point of view.— With this double title, they ought to become the object 
of constant RR with the aim of ameliorating their culture. The following are the means by 
which I have succeeded up to the present time. — First, I cultivate them in pots, the motive 
will soon be apparent, these pots ought to have much greater depth than width, in consequence 
of the extreme length of the CR ida zen of the greater part amongst them, which takes the 
parsnip — the bot f the pots ought to perfectly drained; »i garnished with 
Potsherds or fragments of Bricks, p ap eae the drainage of the waterings. The soil, a compost 
well mixed, and sufficiently rich in vegetable matter. 
the winter, these bulbs, which must do be left in pots, are placed on a very dry shelf 
in the Green S where t iet remain unwatered until the spring; at which time fresh mould is 
given this state they give very soon signs of vegetation; they are then placed in the 
Hot House, SE en are given; the quantity of water being augmented in proportion as they 
shew their shoots. Towards the end of May, they may - = in their place in the Beds, in the open 
air; leaving them always however as I recommended in ir pots 
In this manner one may obtain from these plants a splendid blooming. Towards the beginning of 
e pots must be taken up, and, during the winter, kept in the Greenhouse at an airy place 
near the lights. The oC 2 there complete the ripening of their seeds, or at least of their 
bulbs, from which in spring, the time of repotting, the youngs may be separated. vH
