This interesting and distinct Oak has only 

 recently been made kno«n to science, through 

 the keen observation of its discoverer whose 

 name it bears. 11 is an Oak of medium size 

 attaining the height of 00 or 70 ft., with 

 short trunk 2 or 3 ft. in tliickness vested in 

 sniootliisli or chj-ely ril'licd bark siniihir to 

 tliat of the Pin dak. Similar to tlic I'iii Uak. 

 t.)u, is its liabit of deMdiipiiiu an obliiiig toi- 

 of many upriglit and linii/imtal upper branches 

 and droiipiiig hiwcr braurlics, sending out many 

 small brandies near tin' iirnund. As [lie-e 

 lnwermost ilie in rnnseipKau-L' nf loo mmli -iiaiU' 

 from tJKise aliM\e, they break olf and their 

 liases persist for some lime as stubs i>v pins 

 about the trunk ami. as .Mr. Hill su,i;gests. it 

 IS doul)tless dm. to tlii'se that this and the 

 siintlieru >,). piilusl ris are eouniionly called the 

 Pin t)aks. 



I'rdike the southern species, which i]diabits 

 mainly moist lowdands, this dee is rather an 

 inhabitant of widl-draineil uplamls, tlnaigh 

 sometimes found on the borders of ponds and 

 in low woods. As its habitat is north (d' that 

 of the other tree, the two rangi's o\-erlaii]>ing in 

 the latitude id' nnrtheiu Indiana ami Illinois. 

 and this is already kiH>wn as the I'iu Oak. I 

 suggest tiie name Xortbern Pin Oak as appro- 

 priate to distinguish it from the more sotithern 

 tree.
