Ixxviii Proceedings of the Botanical Society of 



Granada, passing during the journey forests of cork oak 

 (Qncrcns Subcr). In Granada the party inspected the ohve 

 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 

 Sarraccnia purpurea, flava, rubra, variolaris, psittacina and 

 possibly Catesbcci, also to several striking hybrids between 

 these. He showed a pan of densely packed Dionjea 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 i6. 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 dift'erent species of water-lily as determined in 

 the University Garden, also to Oenothera biennis and fruti- 

 cosa, the former of which opened during the evening, the 

 latter during day. Victoria rcgia 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 avicennce opened for one day 

 from 9 a. m. to 3 p. m. ; Hibiscus Trionum lasted from 8 

 a. m. to 10 a. m. ; Inipatiens fulva lasted for one or some- 

 times two days ; Tropo?olum majus for five days ; Phaseolns
