 122 from Port Jackson, and the plant was illustrated by the excellent drawings of Bauer. But here, too, the time was not yet ripe for a morphological understanding of the structure. The megasporangium was thought to be the male flower, the microsporangia being interpreted as capsules containing several seeds (the glochidia). The explanation of the supposed male flower presented difficulties, but he states that the lower cell (i.e. the megaspore) was once found filled with a powder replacing the turbid fluid ordinarily occurring there, and the powder was supposed in some way to be ejected and thence to be conveyed to the female organ.

Ferns also claimed his attention, and among his other contributions he founded the genus Woodsia, calling attention to the character of the involucrum (indusium), which separated it from the other polypodia with which the species had previously been associated.

Brown had always taken a keen interest in fossil plants, although, so far as I am aware, he only wrote one paper on the subject. This one, however, was of considerable importance, for its subject was the Brownian cone of Lepidodendron, called by him Triplosporite, though its true affinities were correctly gauged.

Although, as I have said, Brown was less successful when grappling with cryptogams, he is always worth reading on any subject, and in his own special province, that of the flowering plants, I know of no one amongst the older writers from whom one may learn so much. This is due not only to the genius and erudition which he brought to bear on every problem he attacked, but also to the example he affords of scientific method in handling his subject. In his respect for accuracy, in his cautious attitude, as well as in the single-minded honesty of purpose he everywhere exhibits, he has set an example not only for his own but for all future time.

His personal character made a deep impression on his contemporaries. To his friends he was very faithful, and the unanimous tribute of affectionate (though respectful) admiration affords full proof of this. Like many other strong characters, however, he seems also to have been able at times to shew a
