Heterephaptom'enon [€.<j}a.TrTop.ai, 



grasped), Gams's life-form of more or 

 less parasitic plants ; heterop'loid, 

 used of chromosomes varying in 

 number, as of 21, 5 short, 6 medium, 

 10 long (De Mol) ; Het'erism, normal 

 diversity; Heterocaryo'sis {Kapvoy, 

 a nut), when mycelium is formed 

 from + and — elements containing 

 two kinds of nuclei (BurgefE) ; adj. 

 hetefocaryot'ic ; cf. Homocaryosis ; 

 Heteroca'ry is used for a strain of 

 pure line from a single spore 

 (Brierley); Heterocatarysis (-f 

 Catalysis), chemical change with- 

 out the agent itself suffering loss ; cf. 

 AuTocATALYsis ; Heterochro'mo- 

 somes pi. (+ Chromosomes), aber- 

 rant chromosomes, or allosomes ; 



Heterochro'my, colour differences 

 between individuals of the same 

 species (Lindman) ; heterocle'ma 

 (KXijixa, a shoot), heterophyllous; 

 Heterodist'yly, with short stamens 

 and long styles in the same plant 

 (Errera) ; Heterogame'tism ( + 

 Gamete), having gametes of 

 different functions, as male or 

 female ; Heteroge'ophytes, sapro- 

 phytic or parasitic cryptogams 

 (Gams) : Heterolyt'ic En'zymes, the 

 power of chemical change not 

 restricted to one way (Armstrong) ; 

 heteromas'tigote {p-dori^, a whip), 

 with one or more anterior flagella, 

 and a trailing one behind (Minchin) ; 

 heteromerist'ic (p-^pos, part), where 

 floral formulas differ, as in the same 

 group of Rubiaceae, where corolla- 

 lobes vary from four to ten (Riley) ; 

 Heterom'ery is the condition ; 

 heteromorph'ous {p.op(f>-q, shape), 

 differing in shape as sterile and 

 fertile whorls in Charads may be 

 unlike. 



Heterophylle'tum, an association of 



Potamogeton heterophyllus Schreb. 

 . Heteroplas'ia (TrAaard?, moulded), 

 abnormal tissues differing from 

 normal, and cells also abnormal 

 (Harshberger) ; adj. heteroplas'tic ; 

 Het'eroplasm, in single spore or 

 pure-line strains, which may occur 

 (Brierley); adj. heteroplas'mic ; 

 het'eroploid, other than diploid ; 

 Heteroplo'idy is the condition (De 

 Mol) ; Hetero'sis, a shortened form 

 of Heterozygo'sis, the diverse effects 

 following a cross between hetero- 

 zygous elements ; Heterostyrism, 

 acM, (2) used by Darwin to replace 

 Heteromorphism ; Heterosty'ly is 

 a synonym ; Heterothal'lism 

 {daXXos, young twig), dioecism ;
