— 224 THE AUSTRALIAN NATURALIST. 
“Snake Flower”: C. canaliculatwm on the western slopes is 
“arrowroot” or “wild banana’ (from the appearance of the 
fruit). “Double tail” is an obvious name for Diuris, but per- 
sonally I never heard a Diuris so called. In Tasmania D. longi- 
folia was called “Donkeys,” the prominence of the upper petals 
being regarded rather than that of the lower sepals, but I pro- 
tested against this name for so beautiful a flower. Years ago, 
when I was at school in Geelong, I remember a boy bestowing 
upon Corysanthes the designation, “Sitting down orchid,” and 
the name has stuck in my mind ever since. It may not be ele- 
gant, but it is certainly descriptive. 
Opour or FLOWERS. 
I say without hesitation that the poet’s phrase of scentless 
bright flowers is a libel on our Australian flora. But a good 
many of our flowers are only noticeably fragrant on bright, 
sunny days, and this seems to me to apply particularly to or- 
chids. The following local orchids may be claimed as distinct- 
ly fragrant: All the Dendrobiums on the list: Sarcochilus Hillii, 
S. olivaceus, Cleisostoma, Cymbidium suave, C. Albuciflorum, 
Thelymitra carnea, Microtis oblonga, Lyperanthus swaveolens, 
Caladenia carnea, C. alba, C. testacea. 
Glossodia major has aromatic leaves (especially when attaib), 
and the flower is odorous but hardly fragrant. Liparis reflexa 
and Acianthus caudatus both have objectionable odours. 
I conclude with the complete list of the district orchids 
known to me. (See pages 225-228). 
Placunanomia.—At the October meeting Miss Rose M. 
Winter exhibited the interesting shell P. ione belonging to the 
family Anomiidae which attach themselves to other shells be- 
coming shaped to the contour of the host shell. They attach 
themselves by means of calcareous byssal plug, the product of 
a gland replacing the byssal gland (which is situated in the 
grove towards the base of the foot) and is elastic and adhesive: 
morphologically it is a calcified byssus. The foot, through not 
being used becomes almost useless, as the shell has not to fend 
for itself, so the byssal plug takes its place.
