1958. Brierley, C. H. Plant hairs. Ann. Kept, and Trans. Manchester Microsc. Soc. 

 1916:55-61. 1918.^A discussion of the nature and location of hairs, of theories regarding 

 the relation of various stimuli to hair production, and of the functions of hairs and other 

 epidermal outgrowths. — C. E. Allen. 



1959. Campbell, D. H. The genus Botrychium and its relationships. Proc. Nation. 

 Acad. Sci. [U. S.] 6: 502-503. 1920.— The embryo of B. obliquum Muhl is described. Rela- 

 tionship to Ophioglossum and to Helniinthostachys and the Marattiaceae is indicated. This 

 species and the two others, B. lunaria (L.) Sw. and B. virginianum (L.) Sw., whose life his- 

 tories are known, probably differ enough in embryo and sporophyte to be placed in three 

 separate genera. — Howard B. Frost. 



1960. Daniel, Lucien. Reactions antagonistiques et role du bourrelet chez les plantes 

 greffees. [Antagonistic reactions and the role of the fusion layer in vegetable grafts.] Compt. 

 Rend. Acad. Sci. Paris 170:1512-1515. 1920.— The fusion layer, especially in herbaceous 

 plants, contains parenchyma which predominates for a long time. The lignified vessels are 

 few and distorted. The fusion layer modifies conduction and hence the quantitative and 

 qualitative distribution of water and solutes. The scion may send off roots either internally 

 or externally. These may penetrate the cortex or pith but rarely the cambium layer. 

 The regenerated branches of the stock often penetrate the cambium layer and thence the 

 cortex, but they have never been found penetrating the pith or dead tissues of the scion. 

 This throws some light on the nature of graft hybrids. — C. H. Farr. 



1961. Gatin, V. C. Recherches anatomiques sur le pedoncule et la fleur des Liliacees. 

 [An anatomical study of the peduncle and flower of the Liliaceae.] Rev. Gen. Bot. 32 : 369-437. 

 Fig. 1-31. 1920. — An attempt was made to determine whether the histological character of 

 these structures might not be valuable in classification. The plants were studied when in full 

 bloom, but before pollination had taken place. The author finds that the number, structure, 

 and distribution of the vascular bundles in the peduncle, coupled with their distribution to 

 the floral parts, can be used to show the relationship of the tribes, genera, and species in this 

 family. In the first chapter nine tribes of the sub-family Lilioideae are covered. — J. C. 

 Gilman. 



1962. Nobe COURT. Sur la structure anatomique des tubercles des Ophrydees. [On the 

 anatomical structure of the tubercules of orchids.] Compt. Rend. Acad. Sci. Paris 170: 1593- 

 1595. Fig. 1. 1920. — The "pedicule" upon which the tubercle is borne has arisen by the 

 concrescence of a branch with a leaf and with the cortical tissue of the adventitious root, the 

 lower portion of which gives rise to the tubercle itself. The vascular system of the branch 

 is a schizostele which varies from a monostele to a pclystele. The upper part of the tubercle 

 is partly cauline and partly radical. The middle and lower portion is entirely that of the 

 polystelic adventitious root. — C. H. Farr. 



1963. Schwede, R. Nochmals iiber die Lupinenfaser. [More about lupine fibers.] Jah- 

 resber. Ver. Angew. Bot. 16: 14-18. 1918.— A discussion of the relative value of various 

 species of Lupinus as a source of commercial fiber. Author describes results of microchemi- 

 cal tests for cellulose, lignin, etc., and compares his results with those of Hanausek. Of the 

 three species which he finds available in sufficient quantity to be of use in the present crisis, 

 he considers the fibers of Lupinus albus less suitable than those of L. lutens and L. angusti- 

 folius. — P. J. Anderson. 



1964. Schwede, R. ZurKenntniss derHopfenfaser. [Investigation of hop fibers.] Jahres- 

 ber. Ver. Angew. Bot. 16 : 8-13. 1918.— A microscopical and chemical investigation of the bast 

 fibers and adjacent tissues of the hop plant (Humulus Lupulus L.) Author finds that the 

 morphological characters are much the same as for other members of the Urticaceae. He 

 believes that the qualities of the fiber are such that they could be used in the manufacture of 

 textiles, at least under stress of such conditions as existed during the world war. The fiber 

 was successfully used in the manufacture of paper.— P. /. Anderson.
