25. GABUNIA, K. Schum. in Engl. Jahrb. xxiii. 224. 



Calyx small to middle-sized, herbaceous, usually eglandular within ; 

 sepals T), free or nearly so, imbricate, oblong to rotandate, obtuse, 

 ciliolate. Corolla salver-shaped ; tube cylindric, slender, more or less 

 widened at the base, often twisted below, with patches of hairs between 

 the filamental ridges, otherwise glabrous or hairy above the stamens ; 

 lobes long, very narrow, oblique, wavy, infiexed and deeply descending 

 into the corolla-tube in bud, overlapping to the left. Stamens inserted 

 near the base ; anthers conniving in a cone, subsessile, free from the 

 stigma, lanceolate-subulate, sagittate ; wings narrow, stout, with 

 rounded edges ; tails rather short, acute ; foot of the connective flat, 

 glabrous ; filaments reduced to a callous swelling ; filamental ridges 

 short, broad, convex. Disc 0. Carpels 2, free. Style filiform, wider 

 above, J-H lin. long; stigma conic- cylindric, 5-grooved, very viscous, 

 with a slightly lobed projecting rim at the base and a short subulate 

 apiculus ; ovules numerous, pluriseriate. Mericarps 2, baccate (?) or 

 subfollicular, divaricate, obliquely ovoid with two lateral ridges or 

 wings joining at the apex into a short fiattened obtuse beak ; pericarp 

 sometimes rather fieshy at first, at length dry, coriaceous, tardily 

 dehiscent. Seeds ellipsoid, embedded in a scanty pulp or coated with 

 a thin aril (?) ; testa crustaceous, finely granular, longitudinally 

 sulcate ; endosperm almost horny, ruminate ; cotyledons flat, shorter 

 than the radicle. — Climbing glabrous shrubs ; stems smooth, fistular. 

 Leaves opposite, papery or chartaceous; nerves usually faint; axillary 

 stipules distinct, very obtuse, joining across the stem into a short 

 tubular sheath, secreting resin when young, without (?) external 

 glands. Flowers rather showy, white, fragrant, in usually paired 

 terminal or pseudolateral few- to more than 10-flowered persistently 

 bracteate racemiform, corymbose or umbelliform inflorescences. 

 Species 7, endemic. 



It was not possible to ascertain from the dried fruits, which I saw, whether the 

 seeds were embedded in a common pulp or each coated with a separate aril. The 

 former seemed to be the case in tlie more baccate fruits of G. eglandulosa, tlie 

 latter in tbose of O. crispifiora.
