II. On THONNINGIA MALAGASICA. 
In 1884 the Herbarium of the British Museum received specimens, preserved in 
. Spirit, of a Balanophoraceous plant sent from Madagascar by the Rev. W. Deans Cowan. 
These specimens, consisting of female capitula in flower, appeared to be a new species 
of Thonningia. The MSS. in which I described it were submitted to Sir J. D. Hooker, 
who had at the time just completed a paper on a male plant and fruiting capitula sent 
by Messrs. Humblot and Parker respectively from Madagascar. Suspecting that our 
plants were the same, he at once, with rare generosity, offered me his MSS. and drawings 
to add to my paper, and Гата thus enabled to lay before the Society a full description of 
this interesting plant. Passages taken direct from Sir J. D. Hooker’s MSS. I have 
placed between inverted commas. 
“Тһе discovery of a Balanophoraceous plant in Madagascar extends our knowledge 
of the geographical range of that curious family, and adds something to that of its 
morphology, and hence of the ‘affinities of its genera. Hitherto only one Tropical- 
African species had been known, the monotypic Thonningia of Vahl, a native of Guinea, 
the original specimens of which, gathered in 1804, and preserved in the Royal Herbarium 
of Copenhagen, were sent to me for examination, and are figured in the Society’s
