metres, and the smooth stem has a diameter of 2 metres. The fruit 

 is a spherical stone-fruit, with a thin, fleshy exocarp, and a very thick, 

 woody endocarp. One or two loculi of the quadrilocular fruit are 

 usually sterile. The acotyledonous embryos are very rich in oil. 

 The paper contains excellent figures of the chief characters of this 

 tree, and illustrates the anatomy of the leaf — R. B. 



Poinsettias, New : P. pulcherrima alba and P. x salmonea Adneti. 



By R. Adnet (Rev. Hort. May 16, 1913 ; pp. 227-8 ; coloured 

 plate). — The plate represents two very attractive forms. P. p. 

 alba is hardly correctly named, as the bracts are yellowish, suffused 

 With light pink; those of the other are of a delicate rose-pink 

 throughout. — C. T. D. 



Poisonous Plants. By J. H. Maiden (Agr. Gaz. N.S.W. vol. 

 xxiii. p. 604). — Olearia viscidula and Vanilla must be added to the 

 list of plants which may irritate the skin. — S. E. W. 



Pollenizers for Fruit (Jour. Dep. Agr. Vict. July 1912). — 

 E. E. Pescott writes, p. 453, that ' Sturmer Pippin ' is found to be 

 one of the best pollenizers for ' Jonathan ' apple, and E. Wallis writes 

 (p. 505) that ' Keiffer ' pear is successfully pollenized by 1 Harrington's 

 Victoria,' ' Howell/ and ' Le Conte/ also that ' Bailey's Bergamot ' 

 is well pollenized by ' Williams' Bon Chretien ' ; spur pruning makes 

 ' Winter Nelis ' bear. ' Early Guigne ' cherry is a very light cropper 

 if isolated, but crops well with ' Black Bigarreau ' and ' Early Lyons.' 

 ' Coe's Golden Drop ' plum is prone to barrenness ; no definite results 

 have so far been obtained by crossing, but 1 Pond's Seedling ' is 

 thought to be likely to prove beneficial as a cross. — C. H. H. 



Pomologists, Lives of Great. By E. A. Bunyard (Gard. Chron. 

 June 14, July 26, Aug. 30, 1913, with portraits). These articles 

 deal with J. B. van Mons, A. N. Duchesne, and 0. de Serres. — E. A. B. 



Potato Clubs, Boys'. By J. C. Hogenson, M.S.A. (U.S. A. 

 Exp. Sin., Utah, Circ. 5 ; Feb. 1912). — Potato Clubs appear to be 

 similar to Corn Clubs mentioned in a previous journal. The first 

 part gives full details respecting choice of seed and cultivation. 

 The second part gives particulars of the constitution of the Club, a 

 copy of the membership card and the rules relating to entrants for 

 the competition. A good feature is the scoring card (see p. 13) and 

 an explanation of the same. 



The circular will prove of interest to persons having allotment 

 gardens or school gardens. 



There is much valuable information in small compass. — W. W. 



Potato Disease, Minimizing Loss caused by (Jour. Bd. Agr: 

 vol. xix. No. 6, pp. 441-443). — An article dealing mainly with the 

 precautions which should be taken to minimize the loss from disease 

 when storing potatos in clamps. — A. S.
