THE ALTAMAHA GRIT REGION 245 



It is interesting to note that this list contains all the gymno- 

 sperms known in the Altamaha Grit region except the two rarest 

 ones (Pinus echinata and Juniperus Virginiana), and that the 

 first seven trees are the same that I had previously designated 10 

 as the seven commonest in the region. Also that 12 of what I 

 considered the 14 commonest trees are among the first 15 in the 

 present list, and 13 of them among the first 17. This section 

 through the middle of the Altamaha Grit region is therefore a 

 thoroughly typical one, as might have been expected. 



Although the herbage was practically all dead at the time 

 mentioned, more native herbs were identified from the train 

 than one would be likely to recognize in traveling at the same 

 speed for a similar distance through a hardwood region even in 

 midsummer. 



To bring out certain differences in local distribution the journey 

 may be divided into three approximately equal parts, namely, 

 from Valdosta to the Satilla River, 54 miles; from the Satilla to 

 the Altamaha, 48 miles; and from the Altamaha to Swainsboro, 

 48 miles; and the plants of each listed separately. In doing this 

 the trees, shrubs and herbs seen more than once will be combined 

 and arranged simply in order of frequency numbers in each 

 column, and evergreens will not be distinguished. If the typo- 

 graphical difficulty of it did not forbid, the same names in differ- 

 ent columns could be connected by lines, to make plainer what- 

 ever differences there are between the three lists of table B. 



The frequency numbers in the first column, notwithstanding 

 the greater distance covered by it, average somewhat smaller 

 than in the other two, because between Valdosta and Douglas 

 I happened to sit on the side away from the mile-posts, and con- 

 sequently did not repeat my notes on each species as often as 

 I did on the remainder of the journey. 



Making due allowance for the circumstance just mentioned, 

 it will be noticed that Pinus Elliottii, Taxodium imbricarium, 

 Ilex myrtifolia, Nyssa Ogeche,. Ilex glabra, Serenoa, Sarracenia 

 fiava, and Helianthus Radula are decidedly more abundant in 

 the southern or coastward or flatter parts of the region, while
