cover (Herb. Willd. fol. 17891), however, has had written upon it 
by Willdenow the published diagnosis of Croton moluccanum 
with the additional note ‘habitat in India’ in substitution of the 
published habitat. The cover contains three specimens of the 
same species of Chrozophora. One of the three was sent by 
Roxburgh to Willdenow as C. asper; the other two were sent by 
Klein to Willdenow as C. plicatum. One of the two sent by Klein 
has smaller and less lobed leaves than the other. The description 
is brief but clear; it alludes to the variability of this species, 
more herbaceous in cultivated ground, more woody and with 
smaller leaves in waste places. The account of the capsules is 
exact. But Willdenow did not observe that this plant so well

ment as regards the specimens of the two different species sent to 
him by Klein under the name C. plicatum was so just. 
In dealing with C. senegalense, Willdenow (l.c. p. 5954) 
adopted Lamarck’s treatment, apparently without suspecting that 
Lamarck had described one plant and quoted another.

evidence, that Geiseler had no opportunity of consulting the speci- 
mens used by Burmann, Lamarck and Willdenow. Again there 
are six species that belong to Chrozophora: —70, senegalensis ; 87, 
Rottlert; 110, tinetorius; 111, viet 112, obliquus; 113,
