138 BOTANICAL GAZETTE 



plcte list of Jefl'erson count}- jilaiits, trusting to Mr. Young's botannit-il acutcness, I in- 

 chuled this species attbesame time foljinvinghnn in llie mistake, which was merely an 

 oversight on his part, of putting tlie timcot tlowering in Maj' and June. Xow it has been 

 discovered again in reasonable abuntlance, specimens have l)een made, and our title to it is 

 withoutatiaw. It is barel>' in full tlower this 6th day of August, thus confirming the date 

 given in Gray's Manual. It is possible thai it has been pas-sed repeatedly for Lyc(ipus,\v\i\c\\ 

 it sometimes resembles at the first l)lush, but the much larger whorls and flowers, and 

 the entire leaves soon separate it from that, and a glance at the devek)ped corolla at once 

 carries us far away from the LabiaUe. — J. M. C. 



Notes on the Flora of Clint(Jn County, Mo. — It was the privilege of the writer 

 to spend a few weeks of the past summer on the prairies of Noi th-western Missouri, 

 and the list of his collection, together with some brief notes are presented to the read- 

 ers of the Gazette. 



The countiy is now uearl}' all under cultivation, so that tracts of unbroken prairie 

 occur only here and there, in areas of 80 or KiO" acres. The water courses, from Clinton 

 countv south to the Missouri river, are heavily wooded. An old resident informed me 

 that when she came to the county fort\'-seven }'ears ago, not a stick of timber was to be 

 seen where now oaks and elms from si. \ inches to two feet in diameter, stand so thick on 

 the ground that it is impossible to drive throngli the forest without clearing. Certainly 

 tree-oTowth in that county must have been very rapid! 



Three-fourths of the timber trees belong to the genus Quercati. Q. iiuhricuria, JIx., 

 forms about one-half of the Oaks and Q. ruhra, L.,nearl3' a fourth ; whiles'/ alha, L., Q 

 olifi(xil»hi(, Mx., Q. i)iifcriiriirpii,Mx., and Q. I'l-i/oix, h. yni\ nrm/u'/nitit, M\., makeup 

 the remainder. The fiora of the woods is strikingly similar to that of .Southern Indi- 

 ana, consisting as it does of such species as Geum strictii/ii, MiniuliDi (ilutas, Gerarditi 

 ■fliiva, Demnodiuni acuminatum. Phryimi /.eptoatachi/d, etc. 



The collection during July and apart of August embraced the following species: 



P(il)/ffiili( i)iri(rniit((, L.,HccA\\s lo hi' vcvy scarce. Only one specimen was secured. 



Trifolvuiii pnitenae, L. Two heads were obtained having the fiowers perfectly white 

 — not even a rosy tinge about them. 



Psordleafloribumla, Nutt., scarce. Half a dozen specimens were found, growing in 

 a clump of Post Oaks. 



Pcfa^oxfenio/i rv>lacfius,^l\. and Pefdlosfcmon run'Iiihix, Mx., vvvy abundant on ojieu 



prairie. The later comes into bloom al>out a week earlier than the former and lias a 



shorter season. 



Aiaorp/ui cnnescenn, Nutt. Plentiful. Certainly the supposition that this plant 



indicates lead ore becomes false here. 



Bapilsid leucaidlui, T. & G. So common that it becomes a troublesome weed in 

 cornfields and pastures. Kacemes often 3 feel long. 



BiiptUid leiicopJai'd, Nutt. Common in rich pastures. 



PotentilUt iirgntu, Pursli . Gray says "common westward," but only one plant was 

 seen. 



/ji/thruinaliitum, Pursh. Common in pastures and by roadside. 



E r 11 lujium yuccmf (ilium, Mx. Abundant. 



Lidtris pycnostacliyn, Mx. Low grounds ; very common. 



S'lli'ddf/o M/s.sinn'ien!<ifi, Nutt. The earliest Solidago. 



Sil])hiuj)i. lacinidtum, L. Not scarce. 



Silphiiim intrgrifoliuiii. Mx. More almndanl llian the last. There seem to be two 

 forms of this species. One is typical except that the stem is not "4-angular" but per- 

 fectly rouml. The other is much more slender, the stem "4-angular and grooved." the
