those raised from the kernels, of either of the species. For the 
methods of budding, and general observations on that subject, see 
page 441, &c. 
It will be very proper on budding those, or any other kinds of 
plants in pots, to place them in the shade for three or four weeks, 
after the operation is performed; or at least to turn the budded 
side of each plant to the north, in order to avoid the drying influence 
of the sun. 
Cut off oranges, lemons, jasmins and other exotics, which were 
inarched in April or May, provided that you find them sufficiently 
united. For the method of doing this, see. the article Grafting by 
Approach] or Inarching, in page 257. 
Watering. 
Carefully attend to the watering of all the plants, giving it to 
each as often as necessary, and in proportion to its consumption; 
observing always to administer it sparingly to the succulent kinds. 
The pouring of water, occasionally, through the rose of a wa- 
tering pot, over the branches of the shrubby kinds, would greatly 
refresh them, and wash off the dust collected on the leaves; which 
would give them a clean and pleasing appearance: but this should 
be done late in the evening when the sun has lost its power for the 
day. 
Such pots as are plunged, must be turned full round in their 
seats, at least once a week, to prevent the roots penetrating into 
the surrounding earth, through the holes in the bottoms of the 
pots. 
The Mexican Ferraria, or Tiger-flower. 
The Ferraria Tigridia, of Curtis, or Tigridia pavonia, of Lin. and 
Willdenow, is of such exquisite beauty, as to merit particular at- 
tention. It is of the Gynandria class, and order Triandria, Its Root 
is a tunicated bulb, producing from one to four stems, from eighteen 
inches to two feet in height, composed of various joints, and 
bearing at each, a plicated oblong lanceolate leaf, from a sheathing 
petiole the length of the internode,' and at the summit an in- 
volucrum, apparently consisting of two lanceolate, ancipital, con- 
duplicate, nearly equal valves, of which the exterior is in fact 
the common spathe or involucre, and embraces the interior with 
its contents; the interior valve, which is exactly opposed to the 
outer one, is the proper spathe of the first flower and embraces it, 
together with the spathes and flowers that are to come in succes- 
sion; the spathe of the second flower is opposed to that of the first, 
and placed between it and the pedicle of the first flower; and so of 
the rest, every spathe being opposed to the one of the preceding 
flower and embraced by it. These spathes are similar in shape, 
but diminish progressively and become more membranaceous. The 
Corolla, or flower, is large and divided into six segments, of which 
the three outer are urceolate at the base, expanded above, and re-
