Richard, autrement il n’ aurais negligé de mettre son nom a la 
Suite du nom specifique, comme il le fait toujours.” 
I had already suspected that this might be the case, and had 
written to Miiller asking him’ whether he intended to make a new 
Species or refer Boll’s specimens to G. turbinatum Michx. He 
returned my letter annotated, and in reply to the above question 
says, “Ad hancce speciem” (to this very species). T. Boll's 
specimens collected in Dallas County, Texas, are represented in 
our herbarium by three packets, one received from M. E. Bescher- 
elle, ex herb. Miiller, and two from the Jaeger herbarium. One 
of these is an autograph specimen from Miiller labeled «‘Physco- 
mutrium pyriforme var. turbinatum,’ and the other was found in a 
package of unnamed mosses collected by Boll, sent by Miiller to 
Dr. Jaeger. The plants all agree, as the Manual says, in being 
“ cespitose” and “ much divided,” some of the stems are 25 mm. 
long, and branch three times.* The leaves are distinctly acumi- 
nate, but the vein is not excurrent, and the margins are distinctly 
serrate above the middle, not “entire at apex.” In my letter to 
C. Miiller I asked about this point, and he says ‘‘apice grosse 
serrata.” In the footnote in the Manual the leaves are said to be 
entire at the apex or nearly so, which seems a strange mistake to 
make, as they had authentic specimens; the capsule, too, is said 
to be without a « collum,” but Miiller says, « Non sed collum apo- 
physatum adest.” Our specimens show the neck,wrinkled and 
contracted below the spore-sac when dry, and stomatose. The — 
Capsules are rather large, nearly 2 mm. long, lid flat and blunt, 
seta 10-15 mm. long, the mouth bordered by twelve rows of 
transversely elongated cells, and quite flaring when dry. The 
longest leaves are 4 mm. long, and the resemblance of the plants — 
to the lax forms distributed by Sull. & Lesq. Musci Bor. Am. Ed.
