G. pectinata was especially studied, whose rhizome BooDLE3’ had discovered to be 
solenostelic. This has now been confirmed, solenostely with leaf gaps being 
found. It is concluded that Eugleichenia represents a series of reduction forms 
from the Mertensia type (represented by G. flabellata), and that Mertensia includes 
the most primitive species as well as the most advanced (G. fore in which a 
solenostelic structure has been derived from a protostelic.—J. M. C. 
. Ovule of Julianiaceae.—Miss KrrsHaw?* sees in the integumental vascular 
strands and free nucleus of this recently established Mexican family a suggestion 
of relationship between Juliania and Juglans, and especially in the association of 
this structure in both genera with the outgrowth at the base of the ovule known 
as the obturator. The suggested connection with Anacardiaceae is confirmed by 
the integumental vascular strands of Mangifera, but in that genus there is no 
indication of an obturator.—J. M. C 
Chlorophyll in evergreens.—Miss CAcitie STEIN reports%® that crude chloro- 
phyll (i.e., all the pigments) increases in amount with the season, and from 
February to March far more than from March to May; from that time on it seems 
about constant. The chlorophyll proper increases likewise and decidedly more 
than the xanthophyll. This, she suggests, may be due to the conversion of the 
xanthophyll into oa ee but Kout’s experiments strongly antagonize such 
an explanation.—C. R. B 
Stock and scion.—At a meeting of the Botanical Society of France last March 
GRIFFON discussed the results of his numerous experiments in grafting during 
1908,4° and declared that, whatever the plants employed (Solanaceae, Legu- 
minosae, Compositae), and whether the graft was simple or mixed, there was 10 
trace of asexual hybridization, but further confirmation of the specific independence 
of the stock and scion.—C. R. B 
An abnormal Funaria.—Drxon*™ describes a plant of Funaria hygrometrica 
from Tonduff having the perigonial leaves fringed by a double row of protuberant 
and more or less flask-shaped cells which are supposed to function as reservoirs 
of water oC to the paraphyses for keeping the antheridia well supplied.
