which contained upwards of thirteen hundred carefully 
engraved plates of plants, which he had collected in France^ 
Spain, and Italy. The work was edited by Antonio de 
Jussieu, and published in Paris in 1714. 
Mr. Hurst also exhibited some dried plants, recently 
collected by Mr. Wanklyn in the Southern States of 
America. 
Mr. Coward exhibited the following species of Podos- 
temacem, collected by Gardner, in India and Ceylon.—

The Podostemaceae, a little known order of Tropical Aqua- 
tics, closely resemble the Liverworts in habit and general 
appearance, but possess phanerogamous flowers and 
dicotyledonous seeds. The order was placed by Yon 
Martins amongst Endogens, in the near neighbourhood of 
the Naidacese, and by Lindley in his Rutal Alliance of 
Exogens. Gardner considers it to be nearly allied to the 
pitcher plants — Nepenthacese. The difficulties attending 
the position of the order were well illustrated in the 
specimens exhibited, which presented a singular resemblance 
in foliation to Jungermannia and Riccia, and in the first 
view of the pedicillated ribbed capsule to the fructification 
of a moss, but in essential characters the true place appeared 
to be amongst the aquatic Endogens, with the anomaly of 
possessing a dicotyledonous seed.
