White: An Australian Citrus Relative 



121 



It comes up freely as a second growth 

 after the forest has been cleared, and 

 many trees are found along the edges of 

 clearings, in such situations they seem 

 to fruit very heavily, although the 

 trees themselves do not seem to be as 

 healthy as those growing in the shade of 

 the heavy rain forest. 



The description of J\Iicrocitrns ino- 

 dora given by Bailey (in Botany, 

 Bellenden Ker Exped. p. 34, 1889 and 

 Queensland Flora 1. p. 215, Plate 10, 

 1899 — under Citrus) might be ampli- 

 fied by a few details. 



Alicrocitrtis inodora forms a shrub or 

 small tree of rather straggling habit, 

 about 8-12 feet high with a trunk 

 diameter of 13^-2 inches (4-5 cm). 

 The leaves vary considerably in size 

 and trees growing in the open or on the 

 edges of clearings are always similar to 

 those described by Bailey (I.e.) but when 

 growing in the shade of the heavy 

 tropical forest they vary considerably, 

 attaining a greater size, particularly 

 in breadth; leaves up to 7 in. (18 cm) 

 in length and up to 4 in (10 cm) in 

 width being met with. The trees 

 were not in flower at the time of my 

 visit but bore numerous fruits. The 

 fruit is bright lemon yellow when ripe, 

 oblong or obovate in shape, and may 

 be either quite smooth or somewhat 



ribbed, with ribs corresponding to the 

 cells or loculi, although this latter 

 character, stressed by Bailey and 

 again by Swingle, (I.e. p. 577) is a 

 rather unusual, almost an abnormal 

 feature. The larger fruit attain to a 

 length of 23^2 in. (6.5 cm) and are 

 IM in. (3 cm) in diameter, but the 

 average is rather smaller. They are 8 

 celled and possess the characteristic 

 rather loose stalked pulp-vesicles of 

 other species of Microcitrus. 



It is interesting to note in passing 

 that all the Australian species of 

 Microcitrus occur in Queensland. The 

 Queensland flora has very close affini- 

 ties with that of Papua, particularly 

 with the Southern coast of Papua, from 

 which two endemic species of Citrus 

 have been described, viz Citrus papu- 

 ana Bail, and C. Warhurgiana Bail.^ 

 The flowers of both these species are 

 unknown and it would be interesting 

 to note into which genus — Citrus or 

 Microcritus — at least one of them 

 should be placed. C. papuana pos- 

 sesses a large orange-like fruit and a 

 leaf with a winged petiole; it is no 

 doubt a true Citrus. C. Warburgiana, 

 on the other hand, bears a small fruit 

 and short stalked leaves: it may when 

 better known, have to be classed under 

 Microcitrus. 



The Psychopathic Child 



Juvenile Delinquency, by Herbert 

 Henry Goddard, director, Ohio 

 Bureau of Juvenile Research. 

 Pp. 120. New York, Dodd, Mead & 

 Co., 1921. 



American courts are picking up many 

 thousands of delinquent boys and girls 

 every year. "A very small percentage 

 of them are ever restored so as to con- 

 tribute their share to the general wel- 

 fare. The most of them are always a 

 burden and many of them become our 

 most dangerous criminals." To rem- 

 edy this state of affairs, the first thing 

 necessary is a careful study of these 

 juvenile delinquents, and Dr.Goddard's 



little book is in large part devoted to a 

 description of the work of the Bureau 

 which he heads. He undertakes to offer 

 no ready-made program of remedies, 

 but he does stress the importance of 

 congenital syphilis in the causation of 

 what he considers one of the most 

 serious problems — that of the psycho- 

 pathic child. The feebleminded child 

 is mentally defective, or undeveloped; 

 but the psychopathic child is mentally 

 diseased — it is a case of incipient insan- 

 ity. The author sees great hope for pro- 

 gress in the study of this type, and the 

 study of its relation to syphilis in the 

 parents. — P.P.
