Notes on the Trees of the South-west,"— ^r^/- grandidentatum, 



Nutt. — A few trees of this species, hardly large enough to be called 

 trees, were observed in fruit in July, along streams in the Mogollon 

 Mountains. 



Canotia holacanthay Torr,, grows sparingly upon hillsides in the 

 San Francisco Mountains. Its wood appears to be useless ex- 

 cept as fuel. 



Quercus oblongifolia, Torr. — The shrubby form, doubtfully re- 

 ferred on p. 78 to Q. pungens^ Liebm., belongs here, at least in part, 



Populus bahamifera^ L., var. angustifolia^ is occasionally seen 

 along the mountain streams in the higher altitudes. 



Finns eduUs, Engelm. — Common throughout ; seldom growing to 



be mucH^iore than a foot in diameter. Not observed on the highest 

 mountains. I never found one wath perfect seeds, and was informed 

 that few trees ever produced them in the section where I collected. 



Finns ponderosa, Dougl. — This is the species from which most 

 of the lumber used in the South-west is sawed. It contains a large 

 amount of resin, and, for most purposes, is probably inferior to 

 Cupressus Arizonica, E. L. G., but to no other here found. At an 

 altitude of about 8,000 to 9,000 feet it is ^the predominant species, 

 giving place above to Fseudotsuga Donglasii, Carr., and below to

Vincetoxicum nigrum, Moench., I find abundant here, be- 

 tween Highland Falls and the Point ; more sparingly in Eagle Val- 

 ley. I send this note, thinking the plant may not have been recorded.

Botanical Notes.— 77^^ Corona or Cup of the Narcissus.— ' What 

 pages on pages have been written about this," says tfie editor of the 

 Gardeners' Chronicle (Dr. Masters). "The fact is, it is a botanist's 

 business to ask questions. When he sees a plant it is his business to 

 mterrogate it as best he can ; so when he finds a flower presenting 

 anypecuharity of structure like the cup of the Narcissus, \^ is his 

 business, his duty and his pleasure to ask what it is^how it came 

 there, what it means, and what is its use. The answer he gets to his 

 questions depends very much indeed on the way the question is put.
