larger one, however, corresponds exactly with the species which 
is now growing in many thousands of specimens near Samois on 
the eastern limit of the Forét de Fontainebleau, where I visited 
the different stations with Dr. BLARINGHEM in October 1913. The 
long fruits and the thick flower buds do not leave the least doubt 
concerning the identity of this specimen. 
The most interesting discovery in this field of historical research, 
however, is that of a specimen of O. Lamarckiana Ser. in the col- 
lection of MicHavx, described recently by BLarincHeM.” I had 
the advantage of studying this sheet myself, when I visited Paris 
in October 1913. The printed label says “Herb. Mus. Paris, 
Herbier de l’ Amérique septentrionale d’ANDR& Micuaux.” There 
is no further indication of the locality and no name. The speci- 
men is a main spike, picked in the beginning of the flowering period, 
and without fruits (pl. XIX). It is excellently preserved and 
corresponds in all respects to my cultures of O. Lamarckiana Ser. 
The lobes of the stigma are seen to be widely spread above the 
anthers. The flowers and flower buds are exactly those of the 
present species. : 
_ Awnpré Micwavx died in 1802, after having traveled during 
twelve years through the eastern United States from the Hudson 
River to Carolina. His celebrated collection constitutes one of 
the best sources of our knowledge of the flora of those parts of 
America at the end of the eighteenth century, that is, of the same 
period in which Lamarck published his volumes of the Encyclo- 
pédie. His herbarium is at present at the Muséum d'Histoire 
Naturelle at Paris, and his plants were described after his death 
by his son Francors ANpRé MicHaux in a book entitled 
‘““ANDRAEAS MIcHAUX, Flora boreali-americana, sistens characteres 
plantarum quas in America septentrionali collegit ANDRAPAS 
Micnavx.” Micuavux had the habit of collecting seeds of 3 
many species as possible, besides his herbarium specimens, and of 
sending them to Europe to be sown.
