Plagianthus spicatus, Bth." By Dr. Schomburgk, Adelaide, South Aus- 
tralia. Dr. Schomburgk presented specimens for the museum at the Botanie 
Garden, which had been recently brought to him from Port Lincoln. The 
plant is stated to be very poisonous to sheep and cattle, who die after 
eating it ina few hours. The tops of the flower spikes are considered 
the most poisonous part. After bush-fires the plant springs up in vast 
abundance. The plant belongs to the Malvacew, which contains very

O. Lindberg, Professor of Botany, Helsingfors. Dr. Lindberg said, 
“ This question I propose to all those who have opportunity of examining 
Hydrocharis in flower, in order that the true relation of its orgens of 
female flower is always solitary at the top of an unbranched, robust, and 
darker peduncle. The common peduncle of the male inflorescence issues 
rarely from the same articulation with the fertile one; more commonly, 
so far as I know, from a distinct axis. I have never seen a true male 
plant. In some specimens the male flowers are but little developed, but 
they are easily recognized. It is probable that they are sometimes abor- 
tive. The compound individual of Hydrocharis is so long branched and 
fragile that, even with the greatest care, we can seldom get a plant out of 
the water in a completely unbroken state. Probably it may be from this 
circumstance that the plant has been pronounced dicecious. 1 would suggest
