Sebea. | GENTIANE# (Hill and Prain). 1087 
There appears to be no character to enable the two species S. leivstyla and 
S. transvaalensis both to be maintained, S. leiostyla has therefore a somewhat 
extended range from Nyassaland to Natal, but Buchanan, 270, which is the type of 
Gilg’s species, appears to agree in all essentials with the other specimens quoted. 
The plant collected by Schlechter in the Houtbosch Berg, 4720, which forms the type 
of Schinz’s S. transvaalensis, differs from the other examples in its more bushy 
habit and numerous lateral inflorescences, but in floral character there are no 
essential points of difference from the other specimens included under this 
species, 
59. 8. Macowanii (Gilg ex Schinz in Mitteil. Geogr. Ges. Liibeck, 
xvii. 1903, 47); annual or biennial, erect, simple below, branching 
above, about 5 in. high; leaves few, broadly ovate, acute, 5 lin. 
long, 43 lin. broad, herbaceous ; cymes lax, few-flowered ; calyx- 
segments 54 lin. long, 14 lin. broad, ovate-lanceolate, acute, with a 
keel-wing commencing about the middle and extending to the base 
of each segment; corolla-tube 44-5 lin. long; lobes 5 lin. long, 
24 lin. broad, obovate-elliptic ; filaments } lin. long ; anthers about 
25 lin. long, with apical glands; style 3$-3? lin. long, with 
swelling below the middle ; stigma bilobed, ?—3 lin. long, thick and 
fleshy. : 
Coast Reeion: King Williamstown Div. ; low hills around King Williamstown, 
1500 ft., Tyson, 2203 ! 
A small single specimen with four flowers, conspicuous by the large calyx- 
segments, with the wing prominent only on the lower portion. 
60. S. imbricata (A. W. Hill in Kew Bulletin, 1908, 331); 
perennial or biennial, simple or branched, erect, 7-10 in. high, 
stout ; internodes short, 3-6 lin. long ; leaves numerous, orbicular- 
ovate or cordate, apiculate, 4-44 lin. long, 5}—4} lin. broad, some- 
what coriaceous; inflorescences many-flowered, much-branched, 
forming a dense cymose corymb ; branches 3-4 lin. long ; pedicels 
about 1 lin. long; calyx-segments 4}—5 lin, long, about 15-2 lin. 
broad, ovate-lanceolate, acuminate, overlapping widely at the base, 
with wing § lin. broad, broadest at the base ; corolla-tube 3-3} lin. 
long ; lobes 34—4 lin. long, 14 lin. broad, elliptic-obovate, apiculate ; 
filaments 1—} lin. long; anthers 1} lin. long, with small apical 
gland ; style 34-4 lin. long, with swelling near the base ; stigma 
capitate-clavate. 
: Eastern Recion: Natal; summit of Amajuba Hill, 8000 ft., Burtt Davy, 
747c! 
This species is distinct, owing particularly to the dense corymbose inflorescence 
and the long calyx-segments, which overlap widely at the base ; it shows some 
resemblance to S. Rehmannii and S. polyantha in floral structure. 
61. S. polyantha (Gilg in Engl. Jahrb. xxvi. 95); annual or 
_ biennial, erect, richly branched above, 10-12 in. high ; leaves ovate- 
orbicular or cordate, subacute, somewhat coriaceous, 3—5 lin. long, 
4-5 lin. broad ; inflorescences elongated, composed of 1—5-flowered 
- axillary cymes; branches 1-2 lin. long ; pedicels about 1 lin. long ;
