Greene at Berkeley labeled “ Pinus macrophylla, Engelm, 
collected on the Sierra Madre mountains near Chihuahua,” 
bears an elongated, immature, tuberculated cone not much 
unlike some of ours from the Huachuca Mts., and Prof. Sar- 
gent states that his seeds of latifolia are “imperfect and 
probably not fully grown,” from which we may suspect that 
his cone was immature, in which case the shrinkage in 
drying would aggravate the appearance of “ stout, projecting, 
mammillary umbos.” 
The localities where this pine has been detected—the Sierra 
Madre, Chirricahui, Huachuca, and Santa Rita mountains— 
are quite near each other and similarly environed with gray- 
elly plains, arguing similarity of tree products; and, except- 
ing the aberrant cone characters described, these pines seem 
identical in all respects.

UROPAPPUS, Nuttall. 
WHEN more than seven years since I sought and seemed to 
find a more natural and satisfactory classification of certain 
Californian plants which Asa Gray had confused under the 
generic name Microseris, I erred in taking up for a certain 
genus the Candollean name Calais, instead of Uropaprus of 
Nuttall. The type of Calais was proven to be a genuine 
Microseris; and the species on which I sustained Calais had 
been set apart by De Candolle as a subgenus Calocalais. A 
new name should have been sought, therefore, for a group 
which De Candolle had excluded from his type-section of 
Calais; and such a name, proposed expressly as generic for 
this group, we have in Uropappus. This was published two 
years later than Calais, and the author of it did not know 
that Calais was destined to fall into disuse as being a mere
