NOTES. 
AN ATTRACTION TO FERTILISATION BY INSECTS.—A recent issue of the 
Botanical Magazine includes a coloured plate of Maxillaria Fletcheriana 
(t. 8949), and calls attention to the fact that the papillae of the lip are 
unicellular and globose in this species, giving the surface a “ pruinose ” 
appearance, whereas in M. grandiflora and other species, especially in M. 
Lehmannii and M. molitor they are many-celled and forma yellow fur, 
which, by the breaking up of the papille into cells, is converted into a 
powdery mass resembling an accumulation of pollen. The information is 
also given that Janse has studied this phenomenon in M. Lehmannii and 
Porsch in other species of Maxillaria, and they have found that the papille 
contain abundant starch and act evidently as a bait for insects, who, visiting 
the flowers to feed on the papillz, incidently effect pollination. This 
function is apparently in abeyance in M. Fletcheriana, as the papillz are 
reduced to a single cell and destitute of starch. 
DENDROBIUM CAPILLIPES AND D. CARINIFERUM.—Two very interesting 
Dendrobiums have recently flowered in the collection of Lieut.-General 
Sir A. G. F. Browne, K.C.B., Woodside, Lower Bourne, Farnham. The 
first is D. capillipes, a dwarf tufted species discovered by the Rev. C. 
Parish in the Moulmein district of Burmah, and put into commerce by 
Messrs. Low & Co. in 1866. It belongs to the section Fasciculata, in 
which the flowers are produced in lateral fascicles of twos and threes, as in 
D. aureum and D. nobile. The stems are fusiform, 2 to 3 inches long, 
yellowish. Leaves, one or two on each stem, lanceolate, acute. Flowers 
sometimes solitary, but generally in pairs and more, on thread-like stalks, 
in colour golden-yellow, with a deeper blotch on the lip. The specific 
mame refers to the hair-like foot-stalks of the flowers. The variety elegans 
has taller bulbs and the base of the lip dark orange. D. cariniferum 
belongs to the section Formose, also known as the nigro-hirsute, on 
account of the young shoots of many of the included species being clothed 
with short black hairs, sich as D. formosum and D. infundibulum. It is
