XLVII. TAVARESIA, Welw. 
Calyx 5-partite. Corolla large, tubular-funnel-shaped, 5-lobed ; 
lobes valvate in bud, the sinuses between them forming acute pro- 
jecting angles. Corona double, arising from the staminal column ; 
outer corona shortly tubular at the base, then divided into 10 long 
filiform segments, each terminated by a knob, and usually with a 
minute tooth between the pairs of segments that alternate with the 
anthers ; inner corona of 5 narrow lobes incumbent upon the backs 
of the anthers and dorsally connected with the basal part of the 
outer corona by short partitions. Staminal column arising from the 
base of the corolla; anthers ovate-oblong, without appendages, 
incumbent upon the top of the style. Pollen-masses solitary in each 
anther-cell, horizontal, rather large, compressed, pellucid-margined 
along one side, attached in pairs by short caudicles to subulate 
lateral processes from the pollen-carriers. Style not exceeding the 
anthers, flat and pentagonal at the apex. ollicles not seen, but 
produced in pairs (Mrs. Barber), somewhat diverging, narrowly 
lanceolate-fusiform, smooth. Seeds rather small, crowned with a 
tuft of hairs. 
Leafless succulent perennials, branching at the base ; stems erect or ascending, 
6-12-angled ; angles tuberculate-toothed, each tubercle furnished with 3 bristles ; 
flowers 1-4 together at the base of the young stems, successively developed. 
Distris, Species 2, both occurring in Tropical Africa, one confined to it. 
1. T. Barklyi (N. E. Br. in Dyer, Fl. Trop. Afr. iv. i. 494) ; 
stems 3-4 in. high, 3—} in. thick, cylindric, 10—12-angled, deep 
green or tinged with purplish ; angles with very short closely set 
tubercles, each terminated by 3 white bristles; central bristle 
horizontal, the two lateral rather shorter, deflexed and diverging 
from each other at nearly a right angle; pédicels 3} in. long, 
glabrous ; sepals 3-34 lin. long, lanceolate, acuminate, glabrous ; 
corolla outside smooth, pale greenish or greenish-white, spotted with 
purple-red ; inside densely papillate, pale yellowish, covered with 
small (mostly linear in the tube) purple-red spots, except at the 
base, which is entirely purple-red ; tube 14-2 in. long, about 1 in. 
in diam. at the mouth ; lobes spreading, }-} in. long and about as 
broad, deltoid, acuminate; outer corona 4}—5 lin. long, shortly 
tubular at the base, divided into 10 filiform segments terminating 
in pendulous globose knobs, the filiform parts and knobs purple- 
brown, the lower part white, with the margins, some broad stripes 
alternating with each pair of filaments and a few linear spots all 
dark purple-brown ; inner corona-lobes } lin. long, linear, incumbent 
upon the backs of the anthers, which they slightly exceed, dorsally 
connected to the outer corona by short partitions, purple-brown.
