Robinia margaretta sp. nov. 



yA. shrub sometimes propagating by root suckers as well as by seed, 

 1-1.4 m. in height or in cultivation becoming 3 m. high and with a 

 single tree-like stem. Leaves, with linear acuminate herbaceous stip- 

 ules, rarely wdth slender thorns, formed of 15 to 19 (to 23 in cul- 

 tivation), elliptical rather thick firm leaflets, rounded or subcordate at 

 base and rounded or refuse at the mucronate apex, green and some- 

 times appressed canescent as they unfold, becoming essentially glab- 

 rous with age, rachis sparingly hispidulose, petiolule 2-3 mm. long, 

 canescent. Twigs slender glabrous or hispidulose, tan or light chest- 

 nut. Racemes spreading 7-13 flowered ; flowers faintly fragrant, pale 

 lilac or with the vexellum slightly pinkish, and with a yellowish spot 

 in the center, often with nearly white edges, 16-20 mm. long, the 

 short broad calyx 7-10 mm. long, minutely glandular puberulent, the 

 lobes abruptly acute about two-thirds the length of the tube ; pedicels 

 8-10 mm. long, puberulent and sparingly glandular hispidulose as 

 well as the peduncles. The fruit in spreading clusters of 3-7, is linear 

 7-10 cm. long and about 1 cm. wide, tipped by the slender curved style, 

 very thin and sparingly hispid with short spreading bristles. Common 

 on sand hills around Augusta, Ga., growing with longleaf pine and 

 Carya pallida var. arenicola Ashe and near Greenwood, S. C., on red 

 clay uplands with rosemary pine, southern red oak, and white hickory. 

 A specimen from the latter place was cultivated at Washington for five 

 years, fruiting freely, and stock from it distributed. In its small 

 pale fragrant flowers, long racemes, flat pods, and numerous leaflets, 

 this plant is allied to R. pseudo-acacia. It is possible that Tab. 19, 

 Abbott's Insects of Georgia, is intended to represent this species. 



Robinia grandiflora sp. nov. 



B. Hispida var. rosea Pursh, Fl. Am. Sept, (1814). Not R. rosea 

 Loisel in Duham. Arb. Ed. nov. t 17. 



A slender shrub 1-3 mih. in height or in cultivation reaching 5 

 m., propagating extensively by root suckers as well as by seeds. Shoots 

 and twigs mostly soft appressed silky pubescent or also sparingly 

 setulose with weak spreading pale colored bristles ; or vigorous shoots 

 densely hispid near the tips. Leaves 15-30 cm. long, the rachis 

 mostly appressed pubescent, at least when young; leaflets 9-13 (to 17 

 in cultivation), broadly elliptic or broadlj' ovate 4-6 cm. long, mostly 

 rounded at both ends and tipped with a very short mucro, bronze on
