A fewareas have been fairly well worked out but new taxa are continually showing upin nearly all parts of the state. The following represent a few new recordsmade during the year, 1950-51.1.) Si syrinchium Brownei Small. A small species reported in Small'sManual of the Southeastern Flora'*¦ ' in "low swampy ground, coastal plain, S. E.Louisiana", was found along the roadside and adjacent meadows in southern Ar-kansas below El Dorado in April 1950.(2) The following year, April 1951, thiswas again located in several other stations in the same county but along withwhich another species 2.) of Sisyrinchium with flowers that appeared at a dis-tance to be pale blue or lavender. Closer inspection showed that the perianthwas really white with lavender lines through the center and around the edges.Up to the present, the identity of this plant has not been satisfactorily deter-mined. (Dr. Clair A. Browne of Louisiana State University thinks it is a hybridbetween 5. Brownei and another blue species.)3.) For several years plants which appeared to be Iris verna L. have beenobserved in the region of Bauxite in south central Arkansas but no floweringmaterial had previously been found, until specimens were taken in Polk County inApril, 1950, by Miss Aileen McWilliam of Mena. On April 1, 1951, floweringspecimens of this species (or its variety Smalliana Fern.) were found in theOuachita Mts. in Polk County and in the Bauxite region of Saline County confirm-ing previous observations. This is a marked westward extension for this speciesbeyond previously reported occurrence.4.) Pogonia ophioglos soides (L.) Ker. was found for the first time in thestate, in Ferguson Lake, northern Saline County, growing on floating logs whichwere well provided with other vegetation. Included with it was the southern5.) Habenaria quinqueseta (Michx.) Sw. which was also a new record for thislocality. Itmight be noted that this latter species shows a strong honey-likefragrance at night but no odor at all during the day. Ithas previously beenreported only from Grassy Lake in Hempstead County.'^'6'. ) At this same place were found some 30 inch- tall specimens of Calopogonpulche llus (Salisb. ) R. Br. This species is quite common in our wet meadows andprairies but seldom grows more than 10 or 12 inches tall. These specimens, twoor three times that size, were quite surprising although reference to the newGray's Manual^) discloses that the species ranges from "0.7 (northw. ) -9.75(southw.) dm. high". Perhaps these will bear further study since shorter oneshave been collected farther south in Arkansas than these tall specimens taken atFerguson Lake.7.) Dianthus prolifer L., a European visitor, was found for the first timein Fulton County in June 1951. The first of these were found in the mixed sandand gravel margin of Myatt Creek about 8 miles south of Mammoth Spring. Latermore of it was found on a limestone glade some 5 miles farther southwest.8.) Parnassia grandifolia DC., which grows commonly in Missouri to thenorth and in other states adjacent to Arkansas, was seen for the first time inStone County, June '51. Itwas not in flower, but remnants of last seasonsflower stalks and bracts helped in the identification. Specimens taken to thewriter's garden bloomed in October.9.) Oenothera Spachiana T. & G. , a southern representative of this genus,was found near White Cliffs in Sevier County, May 4, '51.'Research Paper No. 1032. Journal Series, University of Arkansas.Paper presented before the joint meeting of the Amer. Soc. of Plant Taxonomists and theSystematic Section of the Bot.

Euonymus obovatus Nutt. was also observed in Stone County in June1951.11.) One of the most unusual additions to the flora of Arkansas and proba-bly that of the U. S. was found in southern Fulton County in June '51. Thespecimen found could not be identified by reference to any American manual butreference to Hegi's Flora of Central Europe''*' disclosed its identity as Sideri-tis montana L. This member of the Labiatae has the general appearance of arobust specimen of Hedeoma hispida but each calyx lobe is terminated by a sharpspine about two millimeters long. The whole plant is noticeably hairy and thesmall flowers are yellow, tipped with red brown to deep brown color. Dr. JulianA. Steyermark has confirmed this identification. Inquiry of the other largeherbaria has disclosed no other specimens of this species from out of cultiva-tion in the U. S.12.) For several years we have been observing quantities of a white flow-ered Houstonia in the southern part of the state. From material submitted toDr. Steyermark he reports that this is a previously underscribed variety ofHoustonia minima. However, certain features suggest that itmay be distinct.This will be officially named and published shortly.13. ) Another southern species to show up along the southern border of Ar-kansas is the little composite Facelis apiculata Cass. This had been observedin the vegetative stage for a period of several years but eluded identificationuntil the spring of '51 when flowering material rendered its identificationpossible.14.) Still another very unusual find was Sporobolus pulvinatus Swallen, asmall member of this genus found on a "salt flat" about two miles north ofCharleston, Franklin County. This was picked up by Mr. Marvin A. Lawson, of theSoil Conservation Service while making a special study of the vegetation ofcertain soil types in Arkansas. The most unusual consideration about this spec-imen is that previously it was known only from Texas, New Mexico, and Arizona.As Dr. J. R. Swallen, curator of the National Herbarium says, "This is a verygreat extension of range, as we have not had any specimens from so far east."Literature Cited1.
