Worls on Gardening and Agriculture. 513 



The third of the " fifty good reasons " in favour of the Or- 

 chido-mania is, the genei-ally long duration of the blossoms of 

 this tribe ; for, though the flowers of Stanhopea, Catasetum, and 

 such genera, are of a fleeting nature, yet many of the Epiden- 

 dreas retain their flower-spikes in perfection for weeks, and 

 even for months, together. The remainder of the Introduction 

 is to be continued in future parts. 



The plants figured in Part I. are, 1. Oncidium leucochilum, 

 2. Catasetum maculatum, 3. Oncidium Cavendishm?»<w, 4. O. 

 ornithorhynchum {Hort. Brit., No. 22683.), and, 5. Cycnoches 

 ventricosum, the details of which will be found in oiw Flori cultural 

 Notices, p. 506., appended to the letterpress. Of Oncidium leu- 

 cochilum is a vignette, representing the mountains of Istapa, 

 exquisitely engraved by Mr. Branston, from a spirited sketch 

 by J. U. Skinner, Esq., made while out at sea, in 1834. At 

 the end of Catasetum maculatum is a full-length portrait of the 

 back of iJlatta gigantea (the cockroach), taken from a specimen 

 in the extensive cabinet of natural history belonging to Miss 

 Charlotte Wilbraham of Rode Hall. The insect arrived in this 

 country in a box of Orchidaceae; upon which, judging from the 

 condition of the plants, he must have made many a hearty meal. 

 At the end of Oncidium Cavendish/a?»«« is a front view of the 

 same insect. Appended to the description on Oncidium orni- 

 thorhynchum is the the front of a ruinous old ecclesiastical 

 building, existing in a village about thirty leagues from the 

 capital of Mexico, in which mass is occasionally performed. 



It is a gratifying proof of the taste and spirit of the wealthy 

 amateurs of plants in this country, that nearly 80 copies of this 

 work are already subscribed for : the total number printed is 

 only 120. Of course, this number can never repay the author; 

 but, happily for him, repayment is but a minor consideration. 

 He deserves, and will obtain, the higher meed of fame. The 

 drawings are chiefly by Miss Drake, and they have been 

 lithographed by Gauci.
