Fannin, 88. Var. y. Tugela River, W. T. Gerrard ! 1058. (Herb. D., Hk., Sd.) 
Very variable in the breadth of the leaves and in the size of the fl. heads. At 
first I had regarded the 3 vars. given above as distinct species, but a comparison of 
numerous specimens shows so many intermediate conditions that I cannot keep 
them separate. Leaves in a. and f. 2-3 in. long, 1-2 1. wide; in f. 2-2 in. long, 
4-5 l. wide, with lateral veins. Heads in a. and y. 1 in. long, 1} in. diam.; in ¥. 
in. long, 4-51. diam. Flowers purple. Pappus white. 
Sect. 5. Prerocoma. (Sp. 8-11.) 
8. D. speciosa (DC.! 1. c. 37); rootstock woody ; stem herbaceous, 
erect, tall, angle-striate, cobwebbed, panicled or corymbose at the sum- 
mit ; leaves linear-lanceolate and lanceolate, elongate, acute or acumi- 
nate, entire, flat, at first thinly cobwebbed, then quite glabrous, netted- 
veined ; heads pedicelled ; inv. scales multiseriate, shining, lanceolate- 
acuminate, concave, pungent, the outer spreading, gradually passing 
below into pungent bracts, continued down the petiole.

Stem 1-24 ft. high, mostly several-headed. Leaves 4-6 in. long, }-1 inch wide, 
tapering much to both ends, with very deciduous cobweb. 
9. D. Zeyheri (Sond.! in Linn, xxiii. p. 71); stem herbaceous, erect, 
cobwebby-canescent, simple or subcorymbose at the summit; leaves 
oblongo-lanceolate or oblong, acute, narrowed at base, soon quite gla- 
brous above and netted-veined, white-woolly beneath, with slightly 
reflexed edges, entire or distantly subdenticled ; heads pedicelled, ovate; 
invol. se. multiseriate, shining, broadly lanceolate-acuminate, concave, 
pungent, the outer spreading or reflexed. Harv. Thes. Cap. t. 68.

Very like D. speciosa, but much more woolly, with broader leaves and iny. scales, 
and no empty bracts on the pedicels. 
10, D. Kirkii (Harv.) ; rootstock woody ; stem herbaceous, erect, 
terete, cobwebbed, corymbose at the summit ; leaves sessile, broad-based, 
lanceolate-acuminate, soon quite glabrous and netted-veined above, 
thinly canescent beneath, with revolute margins, entire; heads pedi- 
celled, ovate ; inv. sc, multiseriate, shining, lanceolate-acuminate, flat- 
tish, pungent, the outer spreading or reflexed. 
Has. Highlands of Bakota Country, Dr. Kirk! (Herb. Hk.) 
Intermediate in appearance between D. speciosa and D. Zeyheri, but differing from 
both in the broad-based, half-clasping leaves, with evidently revolute margins. Inv. 
se. nearly as in D, speciosa, but ne bracts on the pedicel. 
11, D. sessiliflora (Harv.); stem herbaceous, erect, terete, cobweb- 
canescent, several-headed, simple ; leaves oblong or lance-oblong, nat- 
rowed at base, acute, soon quite glabrous and netted above, thinly 
canescent beneath, subserrulate, flat or with subrevolute margins ; 
heads sesst/e in the axils of the upper leaves, ovate; iny. sc. multiseriate, 
lanceolate-acuminate, pungent, spreading.
