130 AMERICAN MIDLAND NATURALIST 



lanceolate herbaceous, having each two linear herbaceous appendages 

 or teeth at the base one on each side. Calyx and sepals enlarging 

 considerably in fruit, and decidedly herbaceous. 



Planta stricte erecta, floribus dense aggregatis, major quam 

 specie; bracteolae ad basim appendice lineari indutae. Folia 

 majora hand vel vix revoluta. 



Although the plant differs most remarkably in habit from the 

 ordinary, and has uniformly appendaged bractlets, together with 

 the other notable characters mentioned, it is scarcely perhaps 

 more than a cultivated variety. The specimen from which the diag- 

 nosis was made, was taken from a plant in cultivation, and at that 

 entirely outside of its natural geographical habitat. The specimen 

 is in the U. S. National Herbarium and is no 2943a "in cultivation 

 at Biltmore, North Carolina," gathered "Aug. 6th, 1897." 



Dasyphora fruticosa (Linn.) Raf. though in our region growing 

 only in bogs, submits readily to cultivation, and usually bears 

 widely different flowers, becomes taller, more bushy, awith crowded 

 flowers and inflorescence. The bracts of American Dasiphorae 

 are not infrequently toothed at the apex, and sometimes an 

 occasional appendage is found at their base. I have not found 

 such basal growths in either cultivated specimens or native grown 

 plants in our region. 



I have advisedly refused to use the older name Pentaphylloides 

 (Morison) Hill (1756), though there can not be any doubt as to 

 the identity of the plant with Rafinesque's Dasiphora, because 

 names ending in oides are objectionable, and many writers have 

 avoided such in spite of priority, — this in spite too of the fact 

 that I first called attention to the synonymy of Dasiphora. 



Limodorum tuberosum var. nanum Nwd., no v. var. 



Plant small 7.5-13 cm. high, from a small ovoid bulb about 



6 mm. long and half as wide; one leaved; leaf 3-6.5 cm. long, 

 (when the plant is in flower) linear lanceolate, acute or acuminate 

 sheathing at the base, scarcely ever 5 mm. wide; base of leaf 

 covered by a single obtuse membranous bract completely sheathing 

 its whole length of about i cm.-i.3 cm. Peduncle often having 

 near the middle a minute ovate clasping bract. The successive 

 years' shoots arise from a bulb at the end of short offsets about 



7 mm. long. Flowers only 2 or 3, racemose, erect, the sessile ovary 

 subtended by a membranous, ovate, somewhat acuminately
