Schrankia uncinata Willd. Miss Meeker reports that Professor Carleton had 

 told her he had seen a white-flowering form of the sensitive brier in Okla- 

 homa. 



Platanus occidentalis L. Professor Smyth has seen trees of this species bearing 

 leaves varying from the normal so as to resemble in shape those of the sweet 

 gum, to which he has given the designation "forma styracifluifolia." 



Amorpha canescens N. This shrub usually grows with several ascending stems 

 from one root, but Professor Smyth has seen plants of this species in the south- 

 western part of the state that had a distinct diminutive trunk, graced with 

 a perfect crown. 



Astragalus caryocarpus Ker. The writer has seen two plants of this species with 

 creamy-white flowers. 



Desmodium dillenii Darlington. It was the writer's good fortune several years 

 ago to find a plant of this species with creamy-white flowers. 



Petalostemon (Kuhnistera) gracilis N. W. K. Professor Smyth has found this 

 species in Pratt county with a decumbent stem and bearing fruiting heads 

 that resembled blackberries. 



Psoralea tenuiflora (floribunda) Psh. Professor Smyth has recorded a white- 

 flowering form of this blue-flowering plant. 



Rosa arkansana Best. This pretty flowering plant presents us with blossoms of 

 all shades of color, from a pale rosy white to a deep crimson, and a pure white 

 form is reported to have been seen in Franklin county by Miss Meeker. 



Opuntia rafinesquii Eng. Professor Smyth has found specimens of this plant 

 with cylindrical joints instead of the usually flattened ones. 



Liatris pictostachya Mx., L. scariosa Willd., L. squarrosa Willd. Professor 

 Smyth records white-flowering forms of these three species of purple-flowering 

 plants. 



Achillea millefolia L. Professor Smyth records plants with rose-colored and 

 others with red-colored flowers, instead of the white, the form usually seen. 



Actinomeris squarrosa N. The writer last summer found a plant of this species 

 that bore on the lower part of the stem leaves beautifully variegated with pale 

 yellow. 



Helianthus annuus L. It is a fairly common sight to see flowers of this common 

 weed that are partly or fully double. These flowers usually bloom some time 

 before the others on the same plant, or before any are seen anywhere else. 

 The change from a single flower to a double is supposed to be caused by some 

 insect working in the flower-head. The paet summer the writer saw a plant 

 that bore pale sulfur-yellow flowers, and also found two plants with variega- 

 ted leaves, the variegation consisting of a portion of the leaf being a pale yel- 

 low while the remainder was of the normal green. 



Helianthus maximiliani Schrader, H. tracheliifolius Willd. These near rela- 

 tives to the common sunflower also often bear partly to fully double flowers. 



Helianthus tuberosus L. Professor Smyth records plants of this species as bear- 

 ing double flowers, like' its cousins above. 



Lepachys tagates L. Professor Smyth records a yellow-rayed form of this plant. 



Polypteris hookeriana Gr. Professor Smyth has found plants of this species in 

 the soutwestern part of the state bearing ray less flowers. 



Silphium integrifolium Mx. Professor Smyth has seen plants of this species 

 which, instead of bearing opposite leaves — the normal form — bore leaves in 

 whorls of three, the leaves of the whorl above being directly above the spaces 

 between the leaves of the next whorl below. The stem of the plant in this 

 case was six-angled.
