Note on the number of the Somatie chromosomes in Funkia. 527 
ConcLusion. It appears certain the number of chromosomes 
in the somatie nuclei of Funkia ovata and Funkia sieboldiana is 
sometbing over forty, and it is probable that it is forty-eigbt. This 
number is double the reduced number of chromosomes, as is normally 
the case in plants.

Illnstrating Miss Sykes note in Funkia. 
All the nuclei figured were drawn from preparations stained with Heiden- 
hajxs haematoxylin. Tliey were all examined with a Zeiss 2 mm objective of 
1. 4. N. A. and Zeiss Oculars 6, 8 and 18 and the figures were drawn with the 
aid of a camera lucida. 
Fig. 1. Prophase of archesporial nucleus of F. ovata. The number of chro- 
mosomes counted is 46. X 1150.’ 
Fig. 2. A section of a similar nucleus. 40 chromosomes are here present 
and at least 6 — 8 are found in the next section. (X 1150.) 
Fig. Sa, b, c. Three consecutive sections of a similar nucleus in a slightly 
earlier stage , the long chromosomes being as yet little contracted. Not less 
than 30 whole chromosomes are present, and in all 44—48 were estimated. 
(X 3500.) 
Fig. 4. Four pairs of chromosomes drawn out from a nucleus, in order 
to show the exact resemblance in size and shape of the members of a pair 
(X 3500.) 
Fig. 5. Obliqne view of telophase seen from inner side of a spindle; 
46 — 48 chromosomes. Obtained from ovary wall, F. sieboldiana. (X 3500.) 
Fig. 6. Section of a metaphase, showing the much contracted chromo- 
somes. (X 1150.) 
Fig. 7 a, b. Two consecutive sections of an archesporial nucleus of F. 
ovata. A third section was lost. In the two figured , thirty-seven chromo- 
somes are estimated on the upper side of the spindle, thirty-five on the lower. 
(X 3500.) 
Fig. 8. Polar view of telophase of a nucleus from the wall of the ovary 
in F. sieboldiana. About 44 chromosomes were counted. (X 3500.' 
Fig. 9a, b. Two successive sections of a nucleus from the ovary wall in 
F. ovata. In Fig. 9a thirty-nine and twenty-seven chromosomes were counted, 
and in Fig. 96, five and twenty-two chromosomes. In all, then, forty-four 
chromosomes were estimated at one pole of the spindle and forty-nme at the 
other. (X 1500.' 
Fig. 10. Polar view of telophase of a nucleus from the ovary wall of 
F. ovata ; about 46 chromosomes. X 1500.) 
Fig. 11a, b. The two ends of a spindle of a nucleus from the ovary wall 
of F. sieboldiana , from two successive sections. Fig. 11a = 45 chromosomes; 
Fig. 115 = 46—47 chromosomes. X 3500.)
