those raised from the kernels, of either of the species. For the 

 methods of budding, and general observations on that subject, see 

 page 433, Sec. 



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 influ- 

 ence 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 

 Abroach, or Inarching, in page 249. 



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 *Floiver. 



The Ferraria Tigridia, of CURTIS, or F. ha-voniaj of LIN. and 

 WILLDENOW, is of such exquite beauty, as to merit particular at- 

 tention. It is of the Gynandria class* and order Triandria. Its Roof 

 is a tunicated bulb, producing from one to four stems, from eigh- 

 teen 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 intcrnode, 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 beweeen it and the pedicel 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-
