Of five seedlings at Broadford, two 

 were 8- and four were 4-merous. 

 As the seed came from the native 

 habitat in Croajingolong the ab- 

 normal growth could not be cred- 

 ited to repeated cultivation.

3-merotis, a small percentage. 



With few exceptions the whorls were characterised by radial sym- 

 metry, and this, taken with other characters such as venation, points to 

 the numerical increase originating in corresponding superfluity of 

 leaf primordia in the young seed rather than to early fission of the 

 growing cotyledon. 



Polyphylly. — Occasionally the whorl of cotyledons was found to 

 be accompanied by a similarly increased whorl of foliar leaves, and 

 in a few instances increase was repeated at successive nodes. 

 Amongst 40 normal Linaria plants several had four whorls, includ- 

 ing that of the cotyledons. The undermentioned species yielded 

 forms with increase of foliar leaves supervening on tricotyly.

 Bifurcation of Axis. — This occurrence, known to some nursery- 

 men as " double-heading." has an economic value at times in that 

 a shrub or tree ordinarily too tall for some situations produces two 

 equal branches near the ground, each being stronger than a lateral 

 branch. 



1. Epicotylous forking of the stem was observed in Cytisus 

 proliferus. This may have been caused by early arrest of the normal 

 shool and consequent production of what might be termed cotylaxil- 

 lary shoots, referred to later in connection with Eucalyptus cornuta. 



2. Supercotylous forking of the stem axis was seen in a specimen 

 of Tilia Americana, the division being about three cm. above the 

 level of the cotyledons. 



dilution of Cotyledons. — It is assumed that the presence of a 

 "midrib" in each half of an over-broad cotyledonary member,
