692 Mr. Brown on the Organs and Mode of 
the same statement is repeated ; and in this work it also 
appears that he regards the glands to which the pollen masses 
become attached in Ophryde» as derived from the stamen, 
and not belonging to the stigma *, as in 1810 I had described 
them. It would even appear, from a passage in his syste- 
matic workt published in the same year, that he considers the 
analogous glands, existing in most other tribes of Orchidee, 
as equally belonging to the stamen: in his ‘‘ Introduction,” 
however, he refers them to the stigma in all cases except in 
Ophrydee. 
Towards the end of 1830 the first part of Mr. Francis Bauer’ S 
Illustrations of Orchideous Plants, edited by Mr. Lindley, was 
published. 
From this work, of the importance and beauty of which it - 
is impossible to speak too highly, it may be collected that 
Mr. Bauer’s opinion or theory of impregnation in Orchidez 
does not materially differ from that of Batsch, Richard, and 
other more recent writers. From one of the figures it appears 
that this theory had occurred to him as early as 1792; and in 
another figure, bearing the same date, he has accurately repre- 
sented the structure of the grains of pollen in a plant belonging 
to Ophrydez, a structure which I had not ascertained in that 
tribe till 1806. Although Mr. Bauer's theory is essentially the 
same as that of Batsch and Richard, yet there are some points 
in which it may be considered peculiar; and chiefly in his 
supposing impregnation to take effect long before the expan- 
* “The pollen is not less curious. Now we have it in separate grains, as in other 
plants, but cohering to a mesh-work of cellular tissue, which is collected into a sort of 
central elastic strap; now the granules cohere in small angular indefinite masses, and 
the central elastic strap becomes more apparent, has a glandular extremity, which is 
often reclined in a peculiar pouch especially destined for its protection. ”—Introduct.
