160 NOTES AND EXHIBITS. 



Bank (A. A. Hamilton; April, 1914); showing a reversion to 

 juvenile leaves, due to arrested growth. Pinnate leaves are to 

 be noted springing from tlie ends of branches from which twigs 

 have been violently torn off; the surrounding phyllodes are more 

 or less attenuated. — (5) Escholtzia californica Cham. Hort.; Yass 

 (Rev. J. W. Dwyer; May, 1911); showing heterotaxy. Adventi- 

 tious buds arise from the recurved margin of the floral receptacle 

 in company with the flower, and, a short distance below, leaves 

 are produced on the peduncle, whose distended recurved base, 

 which represents the floral receptacle, indicates an abortive 

 attempt at flower-production. — (6) ^05« viridiflora Hort. var.; 

 Bot. Gardens, Sydney (J. L. Boorman; August, 1913); showing 

 phyllody of the corolla, petalody of the stamens, and virescence. 

 The upper portion of the petal is lobed, disclosing its foliaceous 

 character; the barren anthers are seated on the central portion 

 of the particoloured laminse, the lower portion being produced 

 into a claw, representing the staminal filament. — {l)Lomatia 

 silaifolia R.Br.; a series of leaves of this plant, exhibiting an 

 exceptionally large range of leaf-variation. 



Mr. Halcro Wardlaw reported the results of his recent daily 

 observations of the temperatures of a numl)er of Echidnas which 

 were living in captivity at the University. The animals had 

 been living in perfect health for the past few months now, so 

 that their temperatures were presumably normal. These are 

 peculiar, inasmuch as they do not remain at a constant high 

 level, like those of higher mammals; nor do they follow the 

 external temperature at a level a few degrees higher like those 

 of reptiles. The temperature of Echidnas varies from 25-33°C., 

 and shows a diurnal variation of about 3°, the highest tempera- 

 tures being in the afternoon. This variation is independent of 

 alterations in the external temperature. During the last few 

 days several of the animals under observation had commenced 

 hibernation, and their temperatures were now at the level of that 

 of the air, but were following the alterations of this exactly. 



Mr. E. Cheel exhibited a series of specimens of seventy distinct 

 forms of cultivated legumes, chiefly belonging to the genus PAase-
