5. ADENOPORCES Small, gen. nov. 



Climbing, somewhat twining shrubs, with much-branched stems. Leaves opposite, 

 with minute, deciduous stipules ; blades leathery, entire, with numerous lateral veinlets 

 between the lateral veins, short-petioled or nearly sessile. Calyx with 8 glands ; sepals 

 broad, persistent, the glands roundish, laterally attached at the base of the sepal-bod)', 

 stalked. Corolla yellow; petals 5, the blades as broad as long or broader, finely toothed. 

 Stamens 10, all anther-bearing ; filaments slender ; anthers globular. Ovary 3-lobed, each 

 carpel with double crest on the back. Styles 3, distinct, unequal. Samaras 3 together, each 

 4-winged, X-shaped, the two upper wings somewhat larger than the two lower ones. 



Type species, Tetraptcris buxifolia Cav.

Leaf-blades ovate, oval, oblong, or elliptic, 1-3 cm. long, obtuse or acutish, glabrous, 

 except the midrib when young, dull on both sides, slightly paler beneath than above, 

 somewhat striate-veined, sessile or nearly so ; inflorescence-branches glabrous or with 

 scattered hairs near the nodes; sepals ovate, 2.5-3 mm. long, glabrous, the glands about 

 one half the length of the sepal-body ; petals yellow, the larger ones 8-10 mm. long, the 

 blades suborbicular or reniform, crenulate ; free portions of the filaments longer than the 

 tube ; samaras red, 1.5-2 cm. long, the body sparingly pubescent, with an incised crest, the 

 wings glabrous, the upper ones oblong to spatulate, the lower ones somewhat smaller than 

 the upper.

6. CALLAEUM Small, gen. nov. 



Climbing shrubs with much-branched stems. Leaves opposite ; blades broad, entire 

 but sometimes with few tooth-like glands near the base, petioled. Calyx with 10 glands 

 adnate to the backs of the sepals near the base, those of adjacent sepals partially confluent; 

 sepals 5, very broad, persistent. Corolla yellow ; petals 5, the blades very broad, erose- 

 denticulate. Stamens 10, all anther-bearing; filaments short; anthers ovoid. Ovary 3- 

 celled ; styles 3, distinct. Samaras 3 together, each with wide distinct lateral wings and a 

 narrow dorsal wing, and intervening thick cockscomb-like appendages. 



Type species, Jubelina nuaraguensis Griseb. 



1. Callaeum nicaraguense (Griseb.) Small. 



Jubelma nicaraguensis Griseb. Vidensk. Meddel. 1853 : 48. 1853. 



Leaf-blades oval or orbicular-oval, 4-10 cm. long, obtuse or abruptly pointed, glabrous 

 or with scattered hairs, especially beneath, often undulate and sometimes with marginal 

 glands near the base, obtuse or acute at the base, relatively short-petioled ; pedicels puberu- 

 lent ; sepals orbicular-ovate, 3.5-4.5 mm. long, the glands about one half the length of the 

 sepal-body ; petals about 12 mm. long, the blades suborbicular, erose-denticulate ; free por- 

 tions of the filaments as long as the tube or shorter ; samaras about 5 cm. wide, the lateral 

 wings reniform, the dorsal wing less than one half as large as the lateral ones, the inter- 

 vening crests longer than the nut. 



Type locality : Segovia, Nicaragua. 

 Distribution : Guatemala and Nicaragua. 



7. GAUDICHAUDIA H.B.K. Nov. Gen. & Sp. 5 : 156. 1822. 

 Trailing or climbing shrubs, with widely branched stems. Leaves opposite ; blades 

 relatively thin, entire, commonly auricled at the base, or sometimes merely cordate or nar- 

 rowed into the petiole, usually pubescent. Calyx with 8 or 10 glands ; sepals 5, relatively 

 broad, persistent, the glands attached to the sepals by their backs. Corolla yellow ; petals
