THE ORCHID WORLD.

possess a constitution which renders them 

 immune from many of the troubles associated 

 with certain species. Hybrids containing 

 Harryanum in their parentage are notable 

 examples of this free-growing condition, and 

 so strong are they that it matters but little at 

 what season of the year the repotting is done,- 

 although when the growth is a few inches 

 high is undoubtedly the most favourable 

 opportunity. Many growers use the same 

 compost mixture for all sizes of plants, which 

 gives fairly good results, although the best 

 success is obtained by selecting the finer 

 material for the small pots and keeping the 

 coarser kind of fibre for the larger specimens. 

 If a large mass of fine grade fibre is pressed 

 closely together there is little room for the 

 necessary aeration, resulting in a sour and 

 water-logged condition, which quickly upsets 

 the health of the plant. Although almost all 

 Orchids require a fairly large amount of 

 water, especially when in growth, it is 

 absolutely essential to provide efficient means 

 of drainage, both in the compost itself and 

 underneath it. In very large pots, say of 

 eight or more inches m diameter, an excellent 

 plan is to insert a small pot in the bottom, 

 placing it upside down and surrounding it 

 with a few crocks. This method provides 

 ample drainage, and has the advantage of 

 keeping the pot light in weight.

In the production of the multitude of 

 Odontoglossum hybrids that now adorn 

 our collections three species stand out 

 meritoriously ; they are crispum, Pescatorei 

 and Harryanum. How many times and in 

 what varied ways have they been intercrossed 

 is a question no one dares to answer, yet 

 almost each succeeding attempt rewards the 

 hybridist with one or more distinct and 

 praiseworthy results. 



Many beautiful varieties of ardentissimum 

 and eximium now exist, and these, as well 

 as fine forms of Lambeauianum, are to be 

 seen in all up-to-date collections. Their wide 

 range of coloration enables them to hold their 

 own against any other section of cool-house 

 Orchid, while their vigorous nature is such 

 that no amateur need fail to cultivate them 

 satisfactorily. 



Our illustrations show three distinct 

 and beautiful hybrids produced by the 

 intercrossing of crispum,, Pescatorei and 

 Harryanum. By the above plan the precise 

 mode of creating them is facilitated. Amethyst 

 is the result of crossing eximium and 

 Lambeauianum ; illustrissimum is produced 

 by crossing" ardentissimum and Lambeau- 

 ianum ; while Dora has for its parentage 

 Pescatorei and Lambeauianum. 



Mr. Frank Reader. — On Wednesday, 

 August 4th, many of the principal exhibitors 

 at the Royal Horticultural Society presented 

 Mr. Frank Reader with a silver salver and a 

 purse of gold in token of their appreciation 

 of his courtesy and never-failing helpfulness, 

 and to mark the completion of twenty-five 

 years' service with the Society. There were 

 eighty-four subscribers.
