nised ; and he gives again the same divisons under the names of 

 these as shorter and more precise : 

 " Ascending branches. 



" A. Pin de Riga, 'pyramide-elance, elongated tapering pyramidal. 



" B. Pin de Riga, pyramide-elarge. 



" C. Pin d'Haguenau ; Pin d'Allemagne, irregular expanded 

 pyramidal. 

 ** Horizontal branches. 



" D. Pin de Geneve elanc4-etale, tapering, but straggling. 



" E, Pin de Geneve ramass6. Pin des Haictes Alpes, oil, de Brianc^on, 

 thick-set and compact." 



Of the first of these types, the Pin de Riga pyramide elance, 

 elongated tapering and pyramidal, he gives the following characters : 



" The trunk is very vertical, sustaining well its great size, often 

 almost cylindrical through upwards of half its height. The branches, 

 of moderate strength, manifestly of equal growth amongst themselves, 

 form a series of regular and symmetrical crowns the tout ensemble^ 

 of which, by its pyramidal form, recals the habit of the Italian poplar. 

 The bark is of a decided reddish yellow, from 1 or 2 metres above 

 the base." 



Under this type he places in his pinetum, pines raised from two 

 different parcels of seed of the Riga pine, received by him from 

 Russia, and a Witepsk pine, raised by him also from seed received 

 from Riga. 



Of this he writes : 



" Of the different lots which I have received directly from Russia, 

 the Riga pine, raised from seed furnished by M. Zigra, is that which 

 offers the most complete type of the elongated tapering pyramidal 

 variety. The mass presents the following characters : The trunk is 

 in almost all perfectly vertical, sustaining well its great bulk, and it 

 is often almost cylindrical throughout half its height or more, the 

 crown is regular and symmetrical, composed of bi'auches somewhat 

 strong, and of manifestly equal growth ; the general form recalling 

 the habit of the Italian poplar. The bark is of a decided reddish 

 yellow from about 1 or 2 metres from the ground, and scaling off; 

 that of the base is not so good, and it is not so rent with cracks as 

 is the case in the greater part of the other lots. 



"The shoots are more forward in spring than those of the Haguenau, 

 and much more, to the extent even often of fifteen days, than those of 

 the Geneva pine, the pine of Ard^che, and their analogies. It is of a 

 pale green and in no way of a reddish hue, the leaf is not so glaucous,
