138 THE CORRESPONDENCE OF SCHWEINITZ AND TORREY 
Gratiola sphaerocarpa—ls this not near our neglecta? 
Lycopus exaltatus. If this is really distinct from L. europaeus 
can it possibly be the plant described in the FI. Graec. [Sibthorp, 
78]? I have only seen the Prod. Fl. Gr. [Sibthorp, 79] & therefore 
cannot decide whether it resembles the plate. L. europaeus, 
with us, looks very much like your plant. 
Carex gynandra we have here, & I could not make it out. I think 
I have several new ones. 
Cyperus uncinatus has a very great range, for I have it from Ver- 
mont, Massach.—Connecticut & N. York—Perhaps it is C. squar- 
rosus of India? You know it is the C. inflexus of Muhl.? C. 
mariscoides—of whom? Our Mariscus cyperiformis (Scirpus! 
cypertformis Muhl.) is now called Cyp. mariscoides by Sprengel, 
but it is not your plant. 
Houstonia longiflora, is H. tenuifolia Nutt. Gen. 
Phacelia parviflora Nuttall thinks is not that plant, though he 
does not name it. . 
Viola eriocarpa.—lIs it distinct from pubescens? V. publescens| B 
Nutt.? 
V, ochroleuca, looks like V. striata Nutt. &c. 
Thaspium actaetfolium. Is it possible this is the real Ligusticum 
actaeifolium of Michaux & which he found on the Banks of the 
St. Lawrence!? 
Sesbania herbacea is Trigonella americana Nutt. 
I find I shall not have room here to make any further remarks 
on your plants, & shall therefore proceed to give the differences 
between your names of my Cryptogamia, & Sprengel’s. I shall 
say more respecting your plants at another time.
