278 THE ORCHID REVIEW. 
There is not the same difficulty in distinguishing L. Dayana from L. 
pumila as is experienced in the case of L. prestans, for the present one has 
the disc of the lip always traversed by five to seven narrow keels, highest in 
the centre, which gives it a very distinct appearance. The flowers are also 
usually darker in colour, the margin cf the side lobes and front lobe of 
the lip being deep purple; they also generally appear rather earlier in the 
autumn, Owing to these differences it can easily be retained as a distinct 
species. 
A very fine flowered variety known as L. Dayana superba, which 
appeared with Messrs. James Veitch & Sons, received a First-class 
Certificate from the Royal Horticultural Society on November 18th, 1879; 
while a similar award was given to the type on January 17th, 1877, when 
exhibited by Sir Trevor Lawrence. 
The following are the references to descriptions and figures :—

Lelia pumila Dayana, Burbidge in Fl. Mag., 1877, t. 249; Belg. Hort.,

1890, viii., p. 242; Gartenflora, Xxxix., p. 169, t. 1319, fig. I, 2. 
Respecting the culture of this group Messrs. Veitch, in their Manual of 
Orchidaceous Plants (11., p- 80), remark that they are best cultivated in 
shallow pans that can be suspended near the roof glass, where they can 
receive a maximum of light, and in a position where there is a considerable 
Tange of temperature between the opposite seasons of the year. The small 
quantity of compost sufficient for the plants to root in must at no time be 
allowed to get dry, and during the growing season water must be liberally 
supplied ; the higher temperature should then be maintained, taking care 
not to let it sink below 55° Fahr. This treatment is evidently consonant, 
as far as practicable, with the climatic conditions of the Pp ratively high 
latitude from which they are brought, and the altitude at which they 
occur in their native country.

LALIA JONGHEANA. 
It is very curious how nearly this handsome species has been lost sight of 
So rare is it that, although described nearly a quarter of a century ago 
we have never seen a flower of it in any shape or form, and only one living 
plant. Nor does any one appear to have again imported it, or even to know 
its exact habitat. It is most allied to L. pumila, but has much larger 
flowers, and is very distinct in other Tespects. It was described in 1872 by 
Reichenbach, who remarked :—‘ Here you have a first-rank novelty. Ah!
