2. X. Holubii, Scott-Elliot in Joura. Bot. 1890, 305 (exclvdhiy 

 the Angola plant and description of corona). Stem 12-18 in. high, with 

 two pubescent lines in the upper part, glabrous below. Leaves sessile 

 or nearly so, 3^—5 in. long, 1-1. 1 lin. broad, linear, acute, glabrous. 

 Umbels lateral and terminal, the lover pedunculate, the upper ses.<^ile or 

 subsessile, hemispherical or subglobose, more than 20-flowered ; flowers 

 small ; peduncles n-''> lin. long, pubescent or with hairy lines like the 

 stem ; bracts 2 lin. long, attenuate, acute, subglabrous ; pedicels 3-4 lin. 

 long, tapering from the base, puberulous. Sepals reflexed. 1 lin. long, 

 lanceolate acute, concave, glabrous. Corolla closely reflexed; lobes 

 2 lin. long, J lin. broad, oblong, acute, glabrous. Coronal-lobes minute, 

 .V lin. long, resembling a small tongue protruding from the hollow at the 

 base of the anthers and directed downwards, narrowly oblong, obtuse, 

 channelled down the face, adnate to the staminal-column, quite free from 

 each other, with no alternating tooth between them. Staminal-column

The preceding species from Angola was confused with this in the original 

 description, and the corona described from the Angolnn plant instead of from 

 Holub's specimen ; however, it appears best to retain the name for the plant for 

 which it was intended. This species and X. decipiens N. E. Br. are allied to the 

 South African A', involucratirm, Dcrnc.
