The Weekly Rorists' Review* 



23 



Cattleya Skinneri in Mr. Harvey's Mexican Collection. 



(Two plants Rrowlng outdoors and carrying 312 flowers.) 



carefully guarded against. A brisk 

 heat should be given the bulbs at the 

 start; 70 degrees at night is not too 

 much. 



Laelia Anceps. 



The flowering period for Leelia an- 

 ceps having passed, any rebasketing 

 or potting should be done at once. It 

 should not be necessary to overhaul 

 these more than once in two or three 

 years, but a little surfacing will be of 

 advantage to many. Plants which have 

 to be pulled to pieces will not establish 

 themselves sufficiently to flower freely 

 the succeeding winter, and it is not 

 good policy, therefore, to repot too 

 many. The various white forms of this 

 charming Mexican orchid possess 

 greater vigor than the colored ones. 

 Their flowers are larger, possess more 

 substance and keep better in water 

 than the ordinary types, and also have 

 a much greater commercial value. Such 

 forms as L. anceps Stella, Sanderiana, 

 Schroederiana and others will carry 

 four to six flowers per stem, and these 

 are worth as much money as the blooms 

 of Cattleya Triana;. This laelia wants 

 a cool, light house in the growing sea- 

 son. The cattleya house is too warm 

 for it. A carnation house, with just 

 sufficient shade to prevent scorching of 

 the foliage, is what they like, and the 

 pans, pots or baskets shouid be hung 

 well up to the glass. 



Laelia Jongheana. 



Laelia Jongheana, which was quite 

 scarce until a decade ago, is now fairly 

 abundant. It is a native of Brazil, 

 and enjoys a little more heat than L. 

 anceps. The cool end of the cattleya 

 house suits it to a nicety, the plants 

 being hung quite near the glass. This 

 variety carries quite large flowers for 

 so small a plant; they are occasionally 

 six and seven inches across and average 

 five inches. The flowers are quite flat 

 and have less character than, for in- 

 stance, L. anceps or L. elegans. The 

 color is generally soft, rosy purple 

 in the sepals and petals, the crisped lip 

 being of a darker shade. Two to five 

 flowers are carried on a sheath. L. 

 Jongheana comes into flower with Cat- 

 tleya Schroederiana, at a period when 



orchid flowers are not overabundant. 

 It grows best in rather small, shallow 

 pans, similar in size to those used for 

 Oncidium Eogersii.

Odontoglossums. 



The old idea about wintering odonto- 

 glossums was to give them a northern 

 exposure, practically sunless, for sev- 

 eral months. In such a house the plants 

 would keep green and make a little 

 growth, rapidly deteriorating when the 

 hot summer waves arrived. A far bet- 

 ter plan, and one now more generally 

 adopted, is to give them a light, sunny 

 house and a temperature of 50 to 52 

 degrees at night. The sun will bronze 

 the foliage, making it tougher and bet- 

 ter fitted to stand the summer heat 

 when it arrives. These odontoglossums 

 can not be grown here as they are in 

 Europe. They are surely the finest of 

 all orchids when well grown, and cat- 

 tleyas have to take a back seat. Their 

 culture in America is, however, always 

 likely to be attended with more or less 

 uncertainty. Some day we may be able 

 to cool houses for them, as we heat 

 them today. If we are ever to grow 

 them well we must gradually accustom 

 them to a higher winter temperature, 

 for the warmer we grow them, the bet- 

 ter are they likely to withstand our 

 trying summers. 



Quite a* few flower spikes are now 

 pushing on the odontoglots and, to 

 protect these from the attacks of 

 snails, a piece of cotton-wool should be 

 wrapped around the base of each spike. 

 The danger of damage from snails is 

 materially lessened if sphagnum moss 

 is not used when potting them. O. 

 citrosmum is now making its new 

 growths, from which it will flower. It 

 is better to keep the plants quite dry 

 at the root for a little longer yet. The 

 plants will flower all the better for it. 



ORCHIDS OUTDOOBS IN MESIICO. 



The photographs reproduced herewith 

 are interesting as showing how orchids 

 thrive outdoors in Mexico. As will be 

 noted, they are not all Mexican species, 

 several dendrobiums being included in 

 the group by the side of which the native 

 gardener is standing. The photograph 

 of Cattleya Skinneri shows how well 

 this does under the somewhat unusual 

 conditions, a total of 312 flowers on the 

 two plants having been counted by Ed. 

 Howard, of Los Angeles, who made the 

 photographs during one of his Mexican 

 trips collecting plants for the Doheney 

 conservatories.
