flowering again in August. ‘“ Shrub 3 to 20 feet high, with 
many long stems, 1 to 3 inches thick, branching only at the 
top. Fruit sweet and pleasant, but emetic.” Lindh. Its pop- 
ular name is Spanish Buckeye. — “ The fertile flowers and the 
fruit, although for several years known to us, have not until 
now been illustrated or described, except by Adolf Scheele,

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 : — 
ASsPICARPA HYSSOPIFOLIA (sp. nov.): caulibus e radice lignescente plurimis erectis 
(6-12-pollic.) ; foliis lineari-lanceolatis basi rotundatis 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.
