PLANTAE LINDHEIMERIANAE. 137 
is largely due to Lindheimer’s aid in the work. At the end 
of the season they appear to have exchanged a set of the col- 
lections made by each during the year, and Roemer, on his 
return to Germany, placed Lindheimer’s with his own bo- 
tanical specimens in the hands of Adolph Scheele, Pastor at 
Heersum near Hildesheim, who prepared a list of the species 
for Roemer’s ‘“Texas,’”’ and published the descriptions in 
Linnaea from 1848 to 1852 in his “Beitrige zur Flor von 
Texas.”” Not only did he publish the ‘new species’ of 
Roemer’s collecting, but also those found among Lindheimer’s 
duplicates,* though he knew that Engelmann and Gray had 
already undertaken to describe these collections in their 
Plantae Lindheimerianae, and so industriously did he con- 
tinue his work that he soon completely outdistanced his 
American competitors and left little for them to describe. 
This may have had something to do with the discontinuance 
of the Plantae Lindheimerianae, but not the slightest blame 
can be attached to Lindheimer, for he doubtless had no idea 
that any publication on his own collection was intended at 
the time the exchange was made. Nor was this the chief 
cause of the discontinuance of Engelmann and Gray’s publi- 
cation, for not only was this left unfinished at the end of the 
Compositae, but also all other lists then in course of publica- 
tion by Gray, asthe Plantae Wrightianae, Plantae Fendlerianae 
and Plantae Novae Thurberianae,—all crowded out by the pres- 
sure of more urgent work and publication, and never com- 
pleted. 
In 1846 the tide of German immigration turned northwest- 
ward to the Piedernales (or Padernales) River, where Friede- 
richsburg was founded in what is now Gillespie County, and 
Lindheimer accompanied a train of settlers to this point early 
in 1847 and collected in this vicinity till September, when he 
pushed still farther north into the Indian country along with 
the Darmstaedter Kolonie,t the so-called “‘communistic col- 
ony of Bettina,” which occupied lands between the Llano 

* Of the species from Texas described as new by Scheele, 73 were col- 
lected by Lindheimer and 66 by Roemer.
