 growth ceases, water must be L^-iven more and more 

 sparingly, always remembering to proportion the length 

 of the resting period to the vigour of the plants and their 

 growth during the pre\-ious season. 



L. giganteus {U'ck,\ and Rclth. /),— This remarkable and 

 beautitul plant is one of the giants of the Orchid family. Travellers 

 state that in its native country its leaves reach a length of Sft., and 

 its flower-spikes a height of lOft. The first plant that flowered 

 in England was in the possession of Sir Trevor Lawrence. The 

 leaves of this plant were plaited, about 4ft. long by 4in. wide, 

 and pointed at the tips. The flower-spike was Sft. Sin. high, 

 and towards the top about fifteen flowers were somewhat loosely 

 arranged. The flow-ers are from 3in. to 4in. across ; the greenish 

 sepals are strap-shaped, and curl back towards the ovary ; the 

 petals, which are broadly oblong, and over i.'.in. in diameter, 

 form a kind of hood over the lip, and are of a pinkish-rose 

 colour. d'he lip is 3iii. long, trowel-shaped in front, narrowing 

 at the base into a pointed spur, which stands out behind the 

 rest of the flower : it is purple, striped with darker lines, and 

 marked on the centre wida three yellow lines. The species was 

 discovered by Dr. \\'elw]tzsch, in 1866, on the banks of the 

 River Congo; it first flowered under cultivation in May, 18S8.

L. Krebsii (Rchb. /.). — On account of the distinct character 

 of its flowers, and the length of time they remain in perfection, 

 this is a useful and desirable garden Orchid. The pseudo-bulbs 

 are green, ^in. to 3in. high, and bear lance-shaped, plaited, 

 bright green leaves, 8in. to i2in. long. The flower-scape is 

 iTjft. to 2ft. high, and from the upper portion it produces from 

 twenty to thirty flowers, each measuring 2in. across ; the sepals 

 are greenish-brown, blotched with dull purple, and the petals, 

 which are three or four times as large, are of a bright golden- 

 yellow ; the lip is three-lobed, the side lobes being erect and 

 similar in colour to the sepals ; the middle lobe is nearly 

 orbicular, notched in front, and of a pale golden-yellow. 

 Introduced from Xatal in 1S67. It flowers from ?\Iay to 

 October. (B. M., t. 5861.) 



L. speciosus (Ji. Br.). — An old and ornamental species, 

 with roundish, underground pseudo-bulbs, and stout, sword- 

 shaped, dark green leaves. The flower-scape is erect, from 2ft. 

 to 4ft. high, the flowers, which are 2in. in diameter, and fragrant, 

 being confined to the upper half; the green sepals are small 

 and reflexed ; the petals are oblong, much larger than the sepals, 

 and of a bright yellow"; the lip is about lin. long, mainly yellow.
