Comments For such a long established species, and one supposedly in cultivation, this seems a remarkably little known species.  I assume the drawing below (from Li Guangzhao) to be reproduced from Baillon's paper in Bull. Soc. Linn. Paris, 2. 1129. (1894). It appears to show a stalked ovary with the stigma sessile upon it.  This unusual arrangement has not been noted by FoC or Tillich.

There is a fine plate ostensibly of A. typica in Curtis's botanical magazine t. 7484 with a description by J. D. Hooker, available at http://www.botanicus.org/page/453959 et seq. Tillich 2005 obviously takes his information on the colouring of the perigone tubes from this plate.  Curtis's plate shows the stigma to be 6-lobed but does not clearly show the rest of the pistil.  In Curtis's plate there appear to be 2 stamens per perigone lobe although the number of stamens is given as 6.
