 Canada. Sargent, t. (iOo. 



A stately, tall tree, the largi-st of the genus. North California is its most 

 soutluM-n limit, so that seeds would i'e(iuire to be collected from as warm a 

 locality as possible in order to ensure success in New South \\ ales. 



(2.) T. Br lino ni (1)1(1, V;\vy\'vvv. "Ilimalayau Ilemlock Spruce." 



A beautiful tree of medium si/e, for the most part tender in England. It 

 should therefore be (|uite liard\- in sheltered situations in oui- coast range.

Tt is, therefore, more likely to succeed in New South Wales than T. ilicer- 



sifolia, the other Japanese sjiecies, which forms a great forest, covering the 



Nikko ^Tountains at an elexation of more than 5,000 feet. 



20. Pseudotsuga.* 



An anomalous genus jjreseiiting utlinities to AOies and Tsikju and less 

 closely to Picea. Kent, in Veitch's Manual, ])roposes to provisionally place 

 Keteleeria with it. 



" Kent, in Veitch's Manual (2nd edition, p. 474), proiidscs to reject the above name 

 (substituting Ahidia) for tlie foUowing i-eason : — An un(!ontli, l)arbarous name, half 

 Greek, half Japanese, "utterly bad in construction," and mislcaditig in sucii meaning as 

 it has, and which I have refused to adopt as a protest against the admission of sucii names 

 into scientific uomcndature. Also, in compliance witli Art. (iO, sect. 4, of the Laws of 

 Botanical Nomenclature, ado))ted at the International Botanical Cf)ngress, held at Paris, 

 in 1SI)7, winch enacts that — Everyone is l)onnd tn reject a name wiiich is formed by a 

 combination ot {\vo languages. 



The Vienna Congress does not make this a valid reason, and the su])ercession of names 

 for such reasons is dangerous.
