woods. This type comprises stout, erect plants with lanceolate leaves 
of intermediate width. They are tough but considerably thinner than 
the leaves of the preceding types and have only two, at the most three, 
layers of palisades. The inflorescences are generally umbelloid and 
contracted. The fruiting stage is reached in September. 
Additional forms will probably become added when the complete 
collection of Scandinavian H. umbellatum material has been tried in 
cultures. As to the systematic and nomenclative side of the question 
no efforts have been made to ascertain whether or not forms similar 
to those discussed above have been distinguished and named by syste- 
matists. To judge from the characteristics of the forms described in 
Scandinavian manuals, viz. f. coronopijolium (Gmel) Fr., f. dunense 
Reyn, /. filifolium Fr. and 7. humile Schum., no difficulty would pro- 
bably be encountered in finding all these forms growing together on 
the same spot.
