Agrostis juncea Michx. 
“In aridis Carolinae.”? The specimen is Sporobolus junceus (Michx.) Kunth, as 
usually understood, 
Since Michaux’s name is untenable on account of Agrostis juncea Lam. 1783, this 
species should be called Sporobolus gracilis (Trin.) Merrill, Rhodora 4: 48. 1902 
(Vilfa gracilis Trin.). T have examined the type in the Trinius herbarium at St. 
Petersburg, labeled ** Zimmermann imisit Carolina [836.’’ 
Agrostis dispar Michx. 
“Tn Carolina inferiore. 
a) 
The specimen is -lyrostis alba 1. 
Agrostis aspera Michx. 
“THinois.”” The specimen is Sporobolus longifolius (Torr.) Wood, and not the 
species to which the name Sporobolus asper (Michx.) Kunth has been applied in 
recent manuals. The latter grass has an acuminate lemma and long-acuminate palea, 
while Michaux’s description states that the flowers are muticous. 
Apparently the earliest name for the plant which has been going under the name of 
Sporobolus asper is Agrostis clandestina Spreng. Mant. Prim. Fl. Hal. 32. 1807, which 
becomes Sporobolus clandestinus (Spreng.). Sprengel’s type has not been ex- 
amined, but the description leaves scarcely room for doubt. The plant is described 
as erect, and, what is particularly to the point, as having long-acuminate ‘corolla 
glumes.”’ The plant was received from Muhlenberg, who also describes it in his 
Descriptio Graminum. Both Muhlenberg and Torrey distinguished between this 
and Agrostis involuta Muhl. (A. aspera Michx.; A. longifolia Torr.) using among 
other characters the shape of the lemma and. palea, acuminate or awned in the first 
and obtuse in the second. 
Agrostis lateriflora Michx. 
“In praecipitibus saxosis fluminis Misissipi ripariis Hlinoensibus [sign for peren- 
nialj.”’ The specimen is Muhlenbergia mevicana (1..) Trin. The panicles are rather 
dense, somewhat branched, and more or less included in the sheaths at base. 
Agrostis racemosa Michx. 
“In ripis sabulosis inundatis fluminis Misissipi [sign for perennial], Affinis A. 
lateriflora.”” The specimen is Muhlenbergia racemosa (Michx.) B.S. P. Glumes 
awned, longer than the acuminate lemma; panicle dense, more or less interrupted or 
lobed. 
Stipa barbata Michx. 
“In sylvis Virginiae Carolinae [sign for perennial].’’ The specimen is Stipa avenacea 
L. On this sheet is also a label which doubtless goes with the next, “Stipa sericea. 
Hab. in Carolina, Georgia maritima.” 
Stipa sericea Michx. 
The specimen is Mihlenbergia capillaris (Lam.) Trin., as described in Small’s Flora. 
Many of thesheets in Michaux’sherbarium bear two labels, one with name and locality, 
the other with a diagnosis, and usually also the name written upon it somewhere as if 
added later. The sheet of Stipa sericea bears a label with diagnosis and name, but the 
other label seems to have been transferred to the sheet of 8. barbata, mentioned above. 
Stipa juncea Michx. 
There is no specimen with this label, but among the Avenas is a sheet marked 
“Montagnes steril. a la hauteurs du Terres,’ which without doubtisthetype. It bears 
the name Avena uniflora with the word jincea written above, and in the manuscript 
diagnosis it is compared with Avena siberica L.,as is the case in the published description 
of Stipa juncea, ThespecimenisStipamacountiSeribn. The description merely states 
that the flower is aristate, but the diagnosis upon the sheet states that the awn is three 
times as long as flower. Michaux’s name can not be used on account of the earlier
