IXxvili Proceedings of the Botanical Society of 
Granada, passing during the journey forests of cork oak 
(Quercus Suber). In Granada the party inspected the olive 
groves and oil presses, also round the city thickets of wild 
oleander showing white, pink, crimson and _ rose-purple 
varieties. 
Mr. Greensmith exhibited a rich set of Heleniums from 
the Dreer collection. He stated that he had raised a set of 
hybrids in which the characters of several species were 
apparently strikingly blended. Some of these he showed 
and left for further examination. 
Dr. Macfarlane drew attention to luxuriant specimens of 
Sarracenia purpurea, flava, rubra, variolaris, psittacina and 
possibly Catesbai, also to several striking hybrids between 
these. He showed a pan of densely packed Dionza seed- 
lings raised in the greenhouses from seed gathered by Mr. 
Goucher and sown by him in July from plants that had 
flowered in the plant houses. 
October 16. Dr. Miller, President, in the chair. Dr. 
Conard spoke on “The Flowering of Some Common 
Plants.” He first referred to the varying blooming period 
each day of different species of water-lily as determined in 
the University Garden, also to Oenothera biennis and frutt- 
cosa, the former of which opened during the evening, the 
latter during day. Vuctoria regia only opened each bloom 
on two successive nights. Some flowers only lasted a few 
hours, others for days or even weeks. Thus Agrimonia 
Eupatoria has each bloom open for three days, Sanguinaria 
for four, Eschscholtzia for five, Digitalis for six, the cran- 
berry for eighteen and Cattleya labiata for about thirty days. 
Some of the Cypripediums may last from forty to seventy 
days. He then compared such results with observations 
made by him during the past summer at Bradford Hills, Pa. 
Thus he found that Abutilon avicenne opened for one day 
from 9 a. m. to 3 p. m.; Hibiscus Trionum lasted from 8 
a.m. to 10 a. m.; Impatiens fulva lasted for one or some- 
times two days; Tropozolum majus for five days; Phaseolus
