SEPTEMBER, 1914-] THE ORCHID REVIEW. 263 
The hybrids cannot be so sharply separated, for some are hybrids 
between the two groups or between parents which behave differently with 
respect to their period of growth and flowering. For example Lelia 
purpurata and L. crispa begin to grow in the autumn months, completing 
their growths early and then flowering almost without resting. When 
these are hybridised with Cattleyas that behave differently the resulting 
hybrids are either intermediate or tend to behave like one or the other 
parent. But it is a safe guide to treat them in the same way as the parent 
they most resemble. 
With regard to resting generally it should be borne in mind that when 
the roots are not active very little moisture is being drawn from the 
compost, except by evaporation, and this again depends upon the time of 
year and the amount of fire heat necessary. Too much water at this- 
period is both injurious to the roots and destructive to the compost, and a 
judicious use of the sprayer between the pots helps to preserve the necessary 
amount of moisture, and renders less direct watering necessary. A pretty 
safe guide when the plants are absolutely at rest is to give only enough water 
to keep the bulbs plump and prevent shrivelling, and it is remarkable how 
little water is required if a proper amount of atmospheric moisture 1S 
maintained. : 
Another way in which the well-being of the plants may be secured is to 
move the plants about, placing those in active growth in the warmest and 
lightest positions in the house, and shifting them to cooler positions when 
resting. 
ERIA sonKaRIs.—A distinct and striking Eria of the Eriura group, 
received from the Singapore Botanic Garden, and which is said to have 
been collected in Borneo, has just flowered at Kew, and apparently belongs 
to E. sonkaris, Rchb. f., a species which was described by Reichenbach in 
1857 (Bomplandia, v. p. 55), from materials collected by Zollinger on Mt. 
Sonkar in the Malayan island of Sumbawa, east of Lombok. The Lindley 
Herbarium contains a single leaf, a small piece of the inflorescence, and a 
sketch of the lip, these having been sent by Reichenbach. It was said to 
be allied to E. abbreviata, Lindl., an imperfectly known Javan species. 
There is also a dried specimen of E. sonkaris at Kew, sent by Mr. J. J. 
Smith as having been cultivated in the Bogor Garden. A dried specimen 
from Mr. H. N. Ridley, collected at Pontianak, Borneo, also appears to be 
identical. The Kew plant has erect stems, over 4 foot high, with six or 
seven lanceolate-oblong coriaceous leaves, about six inches long by ul 
broad, and dense erect spikes six or seven inches long. The pedicels an 
back of the segments are woolly. The flowers are light yellow, and the 
five-lobed lip has a few light reddish streaks on the side lobes. —R.A-R.
