Germination and G-roicth of Sjjccies of Salvia. 357 



germinated (as far as the attacks of slugs at an early period 

 would allow us to determine with exactitude), whilst in the 

 two forms of S. interrupta there was close agreement in the 

 totals, in >S'. pratensis the form S. variegata only produced 

 20 per cent., whilst S. Tcnorii produced 55 per cent. 



So great differences within the limits of what are single 

 species (again with the proviso that the seeds as supplied to 

 us are correctly named in these cases) does not warrant the 

 forming of many inferences. 



The following tables show dates of germination, total per- 

 centages successfully germinated, dates upon which maximimi 

 number of individuals was first observed in each species : — 



I. The following germinated before ten days had elapsed 

 after the date upon which the seeds were sown : —
