Simocheilus. | ERICACEZ (Brown). 365 
This plant varies in a similar manner to S, glabellus and may be only a form 
of that species with a constantly pubescent calyx-tube. 
9. §. hirsutus (Benth. in DC. Prodr. vii. 704); branchlets 
glabrous or pubescent ; leaves 4-nate, erectly imbrieate, 1-2} lin. 
long, linear, subacute, minutely scabrid-tuberculate, more or less 
pubescent or subpilose when young; flowers in small terminal 
clusters, shortly pedicellate or subsessile ; bract 1, leaf-like, + as long 
to as long as the calyx-tube, ciliate ; calyx * to nearly 1 lin. long, 
rigidly and thickly coriaceous or subfleshy, oblong; tube obtusely 
4-angled with 4 ribs alternating with the angles, glabrous; teeth 
alternating with the angles, erectly connivent, deltoid, acute, ciliate ; 
corolla 12 lin, long, tubular, very slender, 4 lin. square at the apex 
and of nearly equal diameter throughout, slightly curved, glabrous ; 
lobes very small, erect, deltoid-ovate, obtuse; anthers exserted, 
basifixed, linear-oblong, spurless ; ovary glabrous; stigma simple.

This chiefly differs from 8. glabellus in its very slender corolla, which is 
scarcely enlarged in its upper part and only half as much in diameter there as it 
is in 8. glabellus. 
10. S. submuticus (Benth. in DC. Prodr., vii. 704); branchlets 
minutely tomentose to somewhat thinly pilose-pubescent; leaves 
4-nate, erect or ascending and more or less imbricate, 1—2 lin. long, 
linear or linear-lanceolate, subobtuse, glabrous, sometimes with a few 
sessile glands on the margins, rarely with a very few hairs; flowers 
subsessile, 3 to many in terminal heads on the lateral branchlets ; 
heads usually 3-4 lin. in diam.; bract solitary or accompanied by 2 
very small lateral bracts at its base, leaf-like, half as long as to as 
long as the calyx-tube, glabrous, sometimes ciliate with minute hairs 
or sessile glands ; calyx 2—% lin. long, tubular-oblong or ovoid-oblong, 
thickly coriaceous or subfleshy; tube 4-angled, glabrous; angles 
obtuse, alternating with 4 small ribs; teeth alternating with the 
angles, deltoid, acute, about half as long as the tube, erect or sub- 
connivent, not ciliate ; corolla 1}-14 lin. long, tubular, }—} lin. in 
diam. at the apex, slightly narrowing from ap2x to base, curved, 
glabrous, the exserted part about twice as long as the calyx; lobes 
about as long as broad, rounded, subtruneate or emarginate, erect ; 
anthers exserted, basifixed, 1 lin. long, linear-oblong, spurless and 
broadly cuneate or subtruneate and minutely angular at the base, often 
in the same flower, rarely with short spurs; ovary glabrous; stigma 
simple. Thoracosperma submutica, O. Kuntze, Rev. Gen. Pl. ii. 390. 
Coast Recion: Caledon Div.; Onrust River, 20 ft., Schlechter, 10397! 
near Swellendam, 500-800 ft., Mund! Fry in Herb. Galpin, 5008 ! 
This differs from S. hirsutus by its glabrous leaves, smaller calyx and stouter 
corolla. The Onrust River plant has its branchlets thinly pubescent instead of 
tomentose and its calyx rather smaller than in the type, but I believe it to be 
this species.
