PICEA 83 



P. Engelmanni, Engl. 



Is an Alpine species of the mountains of Western North 

 America. Introduced in 1863 and reaching 150 feet in 

 height; it is not unlike P. pungens, but is distinguishable 

 by its softer leaves and downy shoots. 



P. Engelmanni, var. microphylla, Hesse (Beiss., ii. 276). 



A compact, branching dwarf form with leaves much 

 smaller than the type; raised in the nursery of Hesse at 

 Weener, East Friesland. This form does not appear to be 

 in cultivation. 



Picea aurantiaca, Mast., var. Hunnewelliana. 



Among the seedlings raised from seed collected by 

 Wilson in China there appeared, at the WeUesley Pinetum, 

 Mass., one which has retained a dwarf habit. I have 

 only seen a photograph of it. It has made a low, dense 

 cushion. Branches stout and ascending with decurving 

 tips. 



P. excelsa, Link. 



One might readily fill a good-sized garden with the forms 

 of the Norway spruce. This is one of the earhest known 

 conifers, and has been cultivated in Great Britain for 

 some hundreds of years, and in every batch of seedlings 

 variations of habit and colour may usually be found: of 

 dwarf forms there are about sixty in cultivation. 



New forms are constantly appearing in seed beds or are 

 discovered in cultivation. Some of these were distinct 

 enough to secure a name of their own, but many others 

 have strayed into cultivation, masquerading as well- 

 known forms for which there happened to be a demand, 

 and in addition to all the varieties described there are a 

 certain number of indistinct forms in cultivation which 

 cannot be separated from forms to which they are closely 

 akin. 



In the middle of the last century, when the known forms 

 were few, most nurserymen propagated their own stock
