together with appropriate venation and a thickened petiole, indicate 

 connation of two leaves l>y their inner margins, or that the fusion 

 has been due to the crowding of primordial papillae. Thus tho 

 following species, in which the forenamed conditions were evident, 

 may be listed as having afforded specimens : — 

 Vittosporum tenuifolium. 

 /'. floribundum. 

 < 'ojtrosmu lucida. 

 Schinus molle. 

 Sterculia (hybrida?). 



Raphanus (Sp.). — In the radish there occurred a form witli 

 trilobed seed leaves due to each leaf consisting of a fuse! 

 pair. 

 I have not observed any but lateral cohesion of two members of 

 polymerous whorls. Fusion of opposed members by their bases, 

 thus giving a perfoliate appearance, may have existed among the 

 many seedlings seen. This feature is less conspicuous, however 

 and if present was unnoticed. The Sterculia had an asymmetric 

 whorl composed id' the two fused leaves and an aborted third. 

 Sterculia (liybrida?) : Amongst '2\. one with bifid leaf. 

 Vittosporum tenuifolium; One only with a bifid leaf. 

 P. Buchanianum : One leaf of a trimerous whorl of cotyledons 



slightly bifid. 

 Daucus Carota.- One cotyledon bifid slightly. In another 

 plant one leaf bifid and the other unequally trifid. 

 (Guppy found 2") out of 135 seedlings of Lepidum 

 sativum with tripartite cotyledons.) 

 Other Abnormalities. — The only instance seen where axillary 

 growths occurred in a very young seedling was in the case of 

 Eucalyptus cor nut a, in which buds were present in both cotylar 

 and foliar axils. The cotyledons were verticillate, and the foliar 

 leaves normal. 



Li 7i aria (purpurea?) cultivated at Kew showed a tendency to pro- 

 duce supernumerary shoots of hypocotylous origin (about o per 

 cent.). When the plants had produced less than a fourth of their 

 mature foliage, or earlier, they were found with a shout developing 

 near the ground, or sometimes hypogeal, and producing 3-merous 

 whorls of foliar leaves. (Masters records a similar occurrence in 

 ].. vulgaris, Anagalis arvensis, Euphorbia peplus and some 

 umbel-liferae. ) 



Malposition of cotyledons occurred in Acacia stricta, the pair. 

 instead of retaining an opposite position, being forced round by the 

 vigorously growing, humiphilous shoot until they were to one side
