﻿THE ORCHID REVIEW. [September, r 9 o 4 . 



recently received from the same collection shows a well-established 

 specimen, bearing nine flowers and a single capsule, and forms a charming 

 little picture. The scapes seem to be mostly twin-flowered. Like its 

 allies, Laslia pumila and L. Dayana, it is very easily grown under 

 moderately cool treatment, and is very effective owing to the large light 

 purple flowers and orange-yellow throat and keels to the lip. It is a 

 spring-flowering species, and varies somewhat in colour, the most richly- 

 coloured form which we have seen being the variety Kromeri, which 

 received a First-class Certificate from the R.H.S. in March, 1901, when 

 exhibited b^Mr. Edward K-romer, Bandon Hill, Croydon. It had bright 

 rose-purple flowers, and a darker band of the same colour on the lip, and 

 thus approached the form figured in the Botanical Magazine (t. 6038). At 

 the .other end of the scale comes the variety Ashworthiae, from the collec- 

 tion of E. Ashworth, Esq., Harefield Hall, Wilmslow, which also received 

 a First-class Certificate from the R.H.S. in the following April. It had 

 silvery white flowers, with the usual orange-coloured keels on the disc. 

 The history of the species was given at page 278 of our fourth volume, 

 and its re-introduction dates from 1898, when an importation was sold 

 by ^Messrs. Sander as Laelia species. Its identity was first recognised 

 when one of the plants flowered with Mr. A. J. Keeling, in the spring 

 of the following year (O.R., vii., p. 173). The plant here figured is out 

 of the same importation, and was only semi-established when the 

 photograph was taken. 



CALENDAR OF OPERATIONS FOR SEPTEMBER. 



By John MaCKAY, The Gardens, Highbury, Birmingham. 

 In the cool Orchid house no warmth from the hot water pipes should be 

 required during this month. Ventilate freely both night and day, and keep 

 the temperature as low as possible ; at the same time keep sufficient 

 moisture in the atmosphere, by damping down when necessary during the 

 day. The cool night air is a great invigorator, and the plants enjoy it. If 

 healthy, robust growth is desired, fresh air, and plenty of it must be given. 

 As the month advances, no doubt an increased amount of artificial heat will 

 be necessary for the warmer houses, but this must be given with care and 

 discretion, or much harm may be the result from too much fire heat. So 

 long as the weather remains favourable, summer temperatures should pre- 

 vail in all the warm divisions, though a slight decrease in those given for 

 the night, should occur as the month draws to a close. Operations of daily 

 occurrence that have been carried out during the summer should now be 

 modified to suit the conditions of the season, each day having a less amount 

 of light and direct sunshine, shading will consequently not be required on
