32. MITRIOSTIGMA, Hochst.; Benth. et Hook. f. 
Gen. Plant. ii. p. 90. 
Calyx-tube campanulate; limb slightly wider, deeply 5-lobed; 
lobes subulate, persistent. Corolla campanulate-oblong or nearly 
salver-shaped, narrowed above the base, much exceeding the calyx ; 
limb 5-lobed; lobes short, rounded, dextrorsely contorted (as seen from 
inside). Stamens 5, inserted on the corolla-tube, included or nearly 
so; anthers sessile, linear, glabrous, dorsifixed. Disk cushion-like, 
glabrous. Ovary 2-celled (or, by failure of meeting of the 2 placentas 
above, l-celled); style filiform, subclavate, exserted, bifid, scarcely 
mitriform at apex ; ovules several (6-12) in each cell, not immersed in 
the rather fleshy placentas, subpendulous. Berry coriaceous, turbinate 
at the base, ellipsoidal, subglobose or subfusiform, 2—1-celled ; seeds 
rather large, compressed; testa coriaceous, subfibrous.—Glabrous 
unarmed shrubs with opposite membranous shortly petiolate leaves, 
ovate acuminate entire stipules,and rather small or moderate-sized 
flowers arranged in small axillary bracteolate cymes. 
A genus of three species, one endemic in Natal, the other two as follows : — 
Leaves 3-5 in. long, nigro-punctate ; lateral veins 4-5 . . . 1. M? subpunctatum. 
Leaves 4-7 in. long; lateral veins 6-8 . . . . . . . . 2 M. Barieri. 
_ The desirability of maintaining this genus seems to me questionable, as the species 
might be relegated to Oxyanthus and Randia, unless indeed the partite calyx-limb 
and the subfibrous texture of the testa be considered good generic characters. 
1. M.? subpunctatum, Hiern. Branches smooth, terete, at 
the extremities somewhat compressed. Leaves elliptic-oblong, obtusely 
narrowed or subacuminate at the apex, attenuate at the base, sparingly 
nigro-punctate above, rather paler beneath, shortly petiolate, 3-5 by 
—1¥ in.; lateral vejns about 4-5 pairs, slender ; stipules 1} in., per- 
sistent, connate at the base, intrapetiolar, rather shorter than the 
petiole. Bracteoles subulate. Cymes axillary, several-flowered. Fruit 
solitary, about 14 by 4 in., oval, attenuate at the base into a short 
stalk, 2-celled ; cells 4~6-seeded ; seeds 1-4 by 3-4 in., impressed on 
the fleshy placentas; testa somewhat fibrous. Calyx-segments (in 
fruit) apparently 5, lanceolate.

The flowers being unknown, the genus cannot be satisfactorily determined; the 
Species may possibly belong to Oxyanthus. 
2. ME. Barteri, Hook. fil. in Benth. et Hook. Gen. Plant. ii. p. 90. 
A small shrub, 3 ft. high, with subherbaceous branches. Leaves 
narrowly elliptical, acuminate at both ends, 4-7 by 1-12 in., lateral 
Yelns about 7-8 pairs; petiole 4-4 in.; stipules }-} in. long, appressed, 
Subpersistent. Flowers scarcely 4 in. long, shortly pedicellate ; 
racteoles subulate, appressed. Calyx scarcely : in. long, glabrous, 
fen. Corolla campanulate-oblong, glabrous on both sides. Anthers 
er long. Ovary 2-celled. Fruit subfusiform, 1-1} by 4-4 in,, 
pitate at the base, narrowed at the apex. Seeds somewhat angular, 
in. diameter, of irregular shape.
