fcibe24. SpEBMACOCBiE. — Elowers hermaphrodite, rarely 1-sexual. 

 Corolla-lobes valvate. Ovary 2 (very rarely 3-4) celled ; style entire, 

 stigmas capitella^te or bifid, rarely 2 or 3^4 elongate style branches ; 

 ovules solitary in each cell, attached to the septa, amphitropous. 

 Truit dry, indehiscert or dehiscent, 2-cocci or capsular, sometimes 

 cireumscissile. Seeds oblong or linear, the hilum ventral, often 

 elongate, very often longitudinally exsculptured on the ventral face, 

 albumen horny or fleshy ; embryo various, radicle inferior. Herbs, 

 rarely iinderahrubs ; stipules setose, very rarely entire. The flowers 

 small and inconspicuous. Examples: Spermdcoce, Bichardsonia ; 

 generally weedy plants; 



Tribe 25. Galieje, — Plowers usually hermaphrodite. Corolla 

 valvate. Ovary 2-celled ; style very often short, branches 2, apex 

 stigmatose or capitellate ; ovules solitary in the cells, amphitropous, 

 anatropous, or semi-anatropous, f unicle attached to the base of septa. 

 Pruit coriaceous or fleshy, very often didymous, indehiscent. Seeds 

 peltate, the ventral face often concave ; hilum broad, albumen horny, 

 embryo curved, radicle inferior. Herbs, rarely undershrubs, the 

 branches 4-angular. Leaves verticillate ; stipules similar to the 

 leaves, then said to be exstipulate, rarely opposite. Examples : Huhia, 

 ■Galmm, Asperula ; often rough weedy plants. Prom the first genus 

 the well-known dye, Madder, is obtained. 



Teibe XVIII. IXOEE^. 

 COFFEA, Linn. 



The Arabic name of the plant is Qahoueh ; and of this word, the 

 Persian Cahwa, the Turkish Cahvey, the Prench Cafe, and our Coffee, 

 are evidently corruptions. Others, "however, give the following as its 

 derivation : — Caffee, a province of Narea in Africa, where the commoa 

 coffee grew in abundance. 



Calyx-tube short, campanulate, turbinate or urceolate ; limb 

 small or obsolete, cleft or obscurely toothed, persistent, not accrescent. 

 Corolla salver or somewhat funnel-shaped, membranous or slightlv 

 coriaceous ; tube short or elongated ; throat glabrous ; limb spreading, 

 5 to 7-partite, rarely 4 or 8-partite ; lobes contorted dextrorsely (as 

 seen from inside) in sestivation. Stamens 5 to 7, rarely 4 or 8, inserted 

 at the mouth of the corolla, exserted or partly included, glabrous ; 

 filaments short or obsolete, or even two-thirds of the length of the 

 anthers ; anthers linear, fixed at the back above the base. Disk 

 fleshy, glabrous. Ovary 2-celled ; style filiform, glabrous, usually 

 shortly exserted, bifid ; lobes linear, spathulate or tapering ; ovules 

 solitary, subpeltately attached about the middle of the ovary or rather 

 lower, amphitropous. Berry ellipsoidal, oblong, or subglobose, more 

 or less fleshy ; pyrenes 2 (one sometimes abortive), papery or 

 coriaceous, convex on the back, flat with a narrow usually deep 

 longitudinal furrow on the face. Seeds plano-convex; umbilicus 

 ventral ; testa membranous, intruded within the furrow of the face ; 

 embryo somewhat curved; cotyledons f oliaceous ; radicle subt.erete, 

 inferior, longer than the cotyledons; albumen horny. Shrubs or 

 small trees with opposite branches and leaves. Leaves ovate or 

 lanceolate, apicTilate intrapetiolar stipules, axillary or terminal solitary 

 or clustered white fragrant hermaphrodite flowers, and bracteoles 

 usually connate into a single or double cup at the base of the calyx or 

 on the short pedicel or peduncle.
