blotters, and, on removal, true to its designation, was found to be absolutely-

Caladenia Patersoni is said to be the largest and the most beautiful of 
all the members of the genus. The flowers are white, or almost so, with- 
long dusky tentacles which are covered with glandular hairs. Dr. Rogers 
calls attention to the illustration,. of this plant in Lindley’s Swan River 
Appendix, plate viiia, in which the colour is incorrectly shown as beings 
very distinctly yellow with purple caudae to the segments of the perianth, 
and purple combings and calli on the ktbellum. 
Caladenia dilatata is probably the best known of the “ spiders,” and 
despite its wide range in the Commonwealth, it is subject to extraordinary- 
few variations. Dr. Rogers once collected specimens in Monarto in which* 
the lateral sepals were non-clavate, and on one occasion he received 
specimens in which the combing of the lateral lobes of the labellum was 
absent. Apart from teratological changes, these were the only morpho¬ 
logical variations that came under his notice. Chromatic variations are, 
however, he says, occasionally met with. They seem , to be due to the 
omission of one of the colours from a three-colour scheme, in a flower 
in which the three primary colours—green, yellow and red—are much im 
evidence. The red is most frequently emitted, causing stripes to vanisht 
from the perianth, and conspicuous markings from the labellum. This gives 
to the flower a strangely unfamiliar appearance. 
Bonatea antennifera.—A native of Rhodesia, and sent to Kew, in 
I 9°5» by C. F. H. Monro, Esq,, Buluwayo. It is closely allied to the well- 
known B. speciosa, Willd., but is much taller, being three feet high, with- 
1 onger leaves and a laxer inflorescence of equally large flowers, and the 
lobes of the lip and petals much more slender. These are about two inches 
long, and antenna-like, in allusion to which the name is given. 
Cymbidium erythrostylum, Rolfe. —This striking species was 
introduced by Messrs. Sanders, from Annam, through their collector 
W. Micholitz, and first flowered by Sir Fred. Moore at the Royal Botanic 
Gardens, Glasnevin. It is allied to C. Parishii and C. eburneum, but is 
more slender in habit. The leaves are over a foot long by’half an inch 
broad, and the infloresence produces several flowers about an inch and 
three-quarters long. Their colour is white, with a few rows of purple dots* 
down the centre of the petals below the middle, while the three-lobed lip is 
closely lined with red-purple. The column is remarkable for its bright 
crimson colour, in allusion to which the name is given.
