No. I. Evidently intended for Sphagnum cymhifoUum Ehrh., a species of 

 the Northern and Eastern States, not collected by any other person in Missouri, 

 and is probably an error of determination or of locality. 



No. 2. Very doubtful, as this is a species of the Northern and Eastern 

 states, although it has been reported from AUenton, Clifif Cave, and Crescent, 

 in the Engelmann Botanical Club List. 



No. 3. Is not identifiable, as it probably was only a herbarium nam.e of 

 Pech's. 



No. 4. Very doubtful, as this is a species of the Northern and Eastern 

 states, and has not since been collected in Missouri. Apparently Pech did not 

 collect Weisia viridula (L-.) Hedw., a very common species on the ground in 

 meadows and pastures, so I presume he must have mistaken this for Rhahdoweisia. 



No. 5. Possibly correct, although the typical form is rare or absent in 

 Missouri, the variety pallidum L. & J. being common on rocky ground in East- 

 ern Missouri. 



No. 6. I am unable to determine whether Pech meant this for Dicranum 

 orthocarpum Austin or for Dicranum orthocarpum Hedw., two species of the 

 Northern and Eastern states not known for Missouri. Apparently Pech did 

 not collect any species of Dicranella, one of which, D. varia (Hedw.) Schimper, 

 is very common on the ground in Missouri, and it may be that this was collected 

 and mistaken for a Dicranum. 



No. 7. Evidently Ceratodon purpureus Brid., a common species on clay 

 banks in woods in the State. 



No. 8. Evidently intended for Leucohryum glaucum (L.) Schimp., a com- 

 mon species on rocky ground in woods in Eastern Missorui. 



No. 9. Very doubtful, as this is a species of the Northern and Eastern 

 states, although reported from AUenton in the Engelmann Botanical Club List. 



No. 10. Probably correct as this is a common species on dry banks in woods 

 in Missouri. Two other species of Fissidens, F. adiantoides and decipiens are 

 common on the ground in woods in the State, but apparently overlooked by Pech. 



No. II. Probably correct, the Ditrichum pallidum (Screb.) Hampe, a 

 fine conspicuous species on rocky ground throughout the State. 



No. 12. Probably correct although not often collected on account of its 

 small size. It is a little curious that Pech collected none of the larger species of 

 Barhtda, particularly B. caespitosa Schwaegr., a conspicuous species so common 

 on rocky ground in Eastern Missouri.
