tion is given of tlie occurrence and development of glandular liairs in Dodonaea viscosa Linn., 

 Acacia rupicola F. v. M., A. armata R. Br., A. pycnantha Benth., A. verniciflua Cunn., Ixodea 

 achilleoides R. Br., Helichrysum semipapposum De Cand., Humea cassiniacea F. v. M., Myo- 

 porum serratum var. insulare R. Br., Myoporum serratum var. viscosum R. Br., and Eremophila 

 latifolia F. v. M. The facts observed throw light upon the structure of the mature gland and 

 are of systematic value. — Eloise Gerry. 



1488. Fletcher, J. J. Presidential address. Froc. Linn. Soc. New South Wales 45: 

 1^7. PL 1-8. 1920. — On pages 24-47 the author discusses The Correct Interpretation of the 

 So-called Phyllodes of the Australian Phyllodineous Acacias. It is suggested that the Austral- 

 ian phyllodineous Acacias should be distinguished from ordinary "phyllodes," (phynodium = 

 "a petiole usurping the form and function of a leaf -blade," Gray), although this definition 

 was originally intended to apply to the flattened leaf-substitutes of these plants. In the 

 Acacias these structures are neither cladodes nor phylloclades as these terms are currently 

 defined. The author, having determined this, proposes the name Euphyllodineae since the 

 so-called euphyllodes of the Australian Acacias are more than simply flattened petioles. 

 Rather they are considered vertically flattened primary leaf axes or common petioles, with 

 pinnae suppressed, which have usurped the form and function of leaves. The leaf development 

 is traced through the seedling stages, species are compared and illustrated, and analogies with 

 other existing bipinnate species discussed. The incorrectness of current ideas about phyllodes 

 is due to : (1 ) Neglect to determine the mode of succession of the pairs of pinnae in the develop- 

 ment of the bipinnate leaves; (2) non-recognition or disregard of the meaning and significance 

 of the presence of Bentham's "seta terminalis" or "recurved or excurrent point" of the common 

 petiole or of its distal component, the rhachis, due recognition of which, especially in seed- 

 lings with only 1 pair of pinnae, is the key to the understanding of the euphyllodia; (3) failure 

 to take into account the fact that the petioles or apparent petioles of known Australian bipin- 

 nate Acacias are short relative to the length of the entire primary leaf-axes or common 

 petioles whereas the so-called phyllodes are longer than the petioles. Reversion-foliage, its 

 characteristics and its absence in several species, is discussed and figured. — Eloise Gerry. 



1489. HocHREUTiNER, B. P. G. Le carpocratere, un nouvel organe du fruit des Malvacees. 

 [The carpocrater, a new organ of the fruit of Malvaceae.] Compt. Rend. Soc. Phys.et Hist. Nat. 

 Geneve 36: 80-81. 1919. — The author found in all species of Cristaria a cup-like structure at 

 the base of the fruit, the function of which seems to be first protective, and then to facilitate 

 the dissemination of the seed. This structure, which has not been mentioned before, is des- 

 ignated as a Carpocrater. — Charles Drechsler. 



1490. Holmes, M. G. A contribution to the study of water-conductivity in sycamore wood. 

 Ann. Botany 35: 251-268. 13 fig. 1921. — This paper is a continuation of studies [see Bot. 

 Absts. 3, Entry 1109] on the constitution of the wood of shoots of various species in relation to 

 their efficiency in the conduction of water and deals with the sycamore {Acer pseudoplatanus). 

 The wood of the 1st year shows a general similarity to those previously studied. The area of 

 the wood in transverse section, the water conducting area in this wood, and the total number 

 of water conducting elements all show, as in previous cases, a simple decline from base to apex. 

 The specific conductivity rises and then falls, and its value is in general near that of hazel and 

 higher than that of ash. The author made observations also on 2nd and later annual rings 

 finding less variation in specific conductivity than in 1st year wood; also the specific conduc- 

 tivity is somewhat lower in value because the vessels are less abundant though wider. — W. P. 

 Thompson. 



1491. Jeffrey, Edward Charles, and Ray Ethan Torrey. Transitional herbaceous 

 dicotyledons. Ann. Botany 35: 227-250. PI. 11-13, 5 fig. 1921.— Bailey and Sixxott have 

 criticized the theory that the herbaceous type in dicotyledons has been evolved from the ar- 

 boreal type by the formation of large rays in relation to the entering leaf-traces, maintaining 

 that it was in large part merely the result of the progressive thinning of the vascular cylinder. 

 The present article is in reply to their criticisms, contradicting many of their statements of
