In sending specimens of plants for investigation it is desirable 
to include the entire plant; if it is too large, portions sliowing 
leaves, flowers, and fruit are sntficient. It is best to prepare the 
speeimens by drying them under pressure between folds of absorb- 
ent paper, otherwise the parts may shrink and break so as to be 
hardly roeogtuKabie. When drietl plants arc sent they should he 
protected fWmi hveakuge In the maJlby being iiiclosedin sheets of 
paper between piei-cs of stiff pasteboard. If specimens arc to be sent 
ftesli, moistcu them slightly and i)nck them tightly in a box or in a 
bundle, wrapping them in heavy pajicr. Write the name of the 
sender on the outside. In the letter accompanying the speciimns 
state whew each plants was collected, the date, the name of the 
collector, and add any other notes in regard to the economic value 
of the plant.

My dear Mr. Wat son, 
I am sending you what seems to me a jjeculiar and 
yet good new species of Coursetia^ from Tewas. It has the habit 
and legumes of the Arizona species, S.glandulosaimicrophylla) . 
It differs from Coursetia as you will see in its inflorescence* 
Yours ti'uly.
