Henuy and Flood — T'^c IhmkeU llijhrid Larch. 59 



The olilost of the hyluid seedlings wore phanted out at Invev, near 

 JJunkehl, in 1904, and were aliout 25 feet liigli wlien seen in lOKi, heing 

 reputed to be then sixteen years old from seed. They are narrow, witli upturned 

 twigs at ttie ends of the ascending branches ; and are strikingly dillerent 

 in habit from tlie wide-spreading true Japanese larch. Mr. D. Keir, the 

 forester, in June, 1919, accurately measured the Inver hybrid larches as 

 follows : — 



Height. Girth at 5 feet from the ground.

Five hybrids, planted at Ladywell Higli Park, in 1907, and three years 

 younger from seed than the Inver trees, show much more even and better 

 growth, being oO to 33 feet in height and 17 inches in girth at 5 feet 

 from the ground. About 100 acres of hybrid seedlings, all of which are 

 very thriving, have been planted out on the Blair Athol and Dunkeld 

 estates. 



Several of the Dunkeld hybrid larches have borne coues with fertile seed, 

 from which seedlings of the second generation have been raiseti 



At the Ladywell Nursery, Dunkeld, one could see in L916 three beds of 

 seedlings of different origin, all two years old, and under the same conditions 

 of soil and treatment. These compared as follows : — 



1. Hybrids of the first generation, raised from one of the ten 

 Larb: leftoleipis trees, a very uniform crop of seedlings, 12 to 17 inches 

 in height. 



2. Hybrids of the second generation, raised from seed of one of the 

 Inver hybrid trees. These averaged 12 inches high, and were very 

 varied in size and appearance, suggesting Mendelian segregation. 



3. Pure LarU Icplolepis, raised from Japanese seed, a very uniform 

 crop of seedlings, 6 to 8 inches high ; or about half the size of tlie 

 first cross. 



We have obtained most of the material for the study of the Dunkeld 

 hybrid larch from a plot* in the BulTalo Park plantatioi\ at Murthly, Perth- 

 shire, which contains 300 trees of the same origin as those at Inver. Planted 



' This plot is described by John Murray, in Trans. II. Scott. Arbor. Soc. xxix, 152 

 (1915). Plate xv, accompanying this interesting article, shows the habit of the Dunkold 

 hybrid larch.
