true Lelia. Messrs. Veitch, in their Orchid Manual, rightly include it under 
this genus and describe it as Lelia lobata, thus maintaining the earliest 
specific name. They add a note to the effect that it is known to occur in 
only one station, and that on the coast of Rio de Janeiro, where it grows 
high up on a bare rock that is washed by the ocean below, and where it is 
fully exposed to the sun from morning till night, a fact of which cultivators 
should take note, the more especially as the species, although growing 
vigorously under the usual cultural treatment of Cattleyas and Lzelias, often 
fails to flower. This species is rarely seen in cultivation, and the flowers are 
still rarer. Mr. B. S. Williams records a fine plant of Leelia lobata superba 
which carried seven spikes of bloom when exhibited by him at the great 
International Exhibition of 1866. 
DestRUCTION oF Wooptice.—An ingenious method of catching 
woodlice is given by J. Henshall in his treatise on “‘ The Cultivation of 
Orchidaceous Plants,” published in 1845. ‘ Procure some bark from a tree, 
about six to nine inches in circumference, and nine inches long; previous 
to the removal divide it in the middle, lengthwise ; when taken off place 
the pieces together, compressing the edges of the one to admit of its passing 
a little way within the other, that the upper may form a roof to the lower 
part to prevent any water from getting in the inside of the cavity ; between 
should be placed a slice of cucumber or potato, the former being preferable 
when procurable. The bark should be tied together at each end, and placed 
on or amongst the pots, with the roof part uppermost, so that the inside 
may always be dry; the woodlice will soon find out this hiding place, 
both for feeding and protection, they may then be destroyed with 
convenience.” 
Disa GRAMINIFOLIA.—This elegant South African Orchid has sepals of 
an intensely bright and beautiful blue, the petals usually purple below, with 
a bright green upper limb, and the lip pale blueor white, edged with dark 
blue or purple. It is quite a common species, and has rather a long 
flowering period. Lindley, in describing this plant under the name 
Herschelia ccelestis, dedicated it to the great astronomer Herschel, who was 
also a keen Orchid lover and cultivator. Unfortunately this species 1s rarely 
seen under cultivation in England. ‘It may be expected,” remarks Dr. H.- 
Bolus (Orch. S. Africa), ‘ that this difficulty will eventually be conquered, 
and if so the species will soon become deservedly popular amongst Orchid 
cultivators. Horticulturists will do well to remember that during its 
flowering period in its native home the plant receives little or no water at 
its roots, being dependent for moisture on what is stored up in its large 
tuber, and upon the occasional mists which envelop the mountain sides.”
