144. THE CORRESPONDENCE OF SCHWEINITZ AND TORREY 
India of which I have a fine specimen—the heads of the latter 
& spikes are not 1/10 the size—besides other remarkable differ- 
ences. C. mariscoides—sent you—lI now find is altogether mis- 
named—since I have found the true one which is your Mariscus 
cypertformis—I do not know what to make of it, unless it be a 
Mariscus? 
Houst|onia] longiflora—I am very glad to learn that this is the 
tenuifol. of Nuttall—it is one of our common plants which I neve 
paid any close attention to & called it by the name our old botany 
had given—I should be glad to get the true longiflora. 
Phacelia parviflora. Muhlenberg always called this’ Polemon. 
dubium—& I think it suits Pursh’s description well enough—but 
nevertheless it may be a new species. It grows exclusively on the 
sandy banks of our rivers—but there very common & in gardens 
becomes very large & an inexterminable weed. 
Viola] eriocarpa. I think is not dist[inct] from publescens| 8 
Nuttall—but certainly from the pubescens of Pursh. It is com- 
mon here—but the pubescens I never found here. 
V. ochroleuca is certainly the V. striata of Nuttall—but extremely 
different from what I call V. striata Leconte, a species which is 
common here, but Mr Leconte tells me, that he has never seen it 
any where else. In my next remittance I hope to send you spec. of 
all mine. : 
Thasp|ium] actaeifoljium|—I have very doubtingly named this 
plant so—but if not right—it is undoubtedly a new species—our 
most disting[uished| Umbellate. It frequently grows—1o feet 
high & spreads 3 or four wide. It is very common in May. 
Sesblania] herbacea. I am extremely glad that you point out the 
true name Trigonella amlericana] which it is beyond a doubt—I 
neglected that Genus in examining it—but it suits exactly. 
Pray continue your remarks as soon as possible. Now concerning 
the Cryptog. plants which I named. 
Hyp|num| lutescens Schw.—I believe ought to be populewm on re- 
examinat(ion]. 
cupressiforme—The cupressif. is extremely various, it is very 
possible that this may be incurvat[um]. : 
hians Sw.—This certainly is not the same with plumos{um| 
Hedw. & agrees with hians of Muhlenberg, unknown to me.
