 flowering again in August. " Shrub 3 to 20 feet high, with 

 many long stems, 1 to 3 inches thick, branching only at the

1 On the southwestern border of Texas, Mr. Wright has detected a Malpighiace- 

 ous plant, which proves to be a third species of Aspicarpa, namely : — 



Aspicarpa hyssopifolia {sp. nov.) : caulibus e radice lignescente plurimis erectis 

 (6-12-pollic.) ; foliis lineari-lanceolatis basi rolundatis subcordatisve sessilibus ; pedi- 

 cellis axillaribus solitariis ; petalis rotundatis eximie crispato-fimbriatis. — On the Rio 

 Grande and Rio Seco, Texas, Mr. Charles Wright. — Leaves scarcely an inch long, 

 one to two lines wide; the midrib and margins hispid-ciliate. Flowers about one 

 third the size of those of A. Hartwegiana ; the petaliferous ones scattered in the axils 

 (not umbellate at the summit of the stem), and fructiferous, either two or three car- 

 pels ripening. These are much as in A. Hartwegiana, but smaller, more upright and 

 acute, deeply umbilicate at the insertion. Fruit from the abnormal, apetalous flowers 

 not seen.
