 G. parviflora, V. sec. Schlecht. .- the proportions of the corolla and calyx does not agree. — A 

 diffuse shrub; leaves shortly petioled, 12"'-4"' long; corolla white; drupe 2'" diam. : calyx- 

 limb tardily deciduous.— Hab. Antigua!, Nichols., Wullschl., Montserrat, Dominica?,

81. G. crispiflora, V. Leaves large, ovate or elliptical, glabrescent or pubescent on 

 the curved primary veins beneath : stipules large, ovate, menbranaceous, strigose within ; 

 peduncles deeply 2-fid : flowers numerous, distant : bracts minute, much shorter than the 

 oblong calyx-tube ; corolla tomentose : tube clavate (6'" long), 5-6 times as long as the 

 calyx: lobes 5, lacerate-undulate, glabrous within; drupe shortly oblong, acute-angled, 4- 

 seeded. — Vahl, Eclog. t. 6. — G. membranacea, Sieb. Mart. 57 ! (non Sw.). — A slender 

 shrub, 10' high; leaves 5"-12", petioles l"-3", stipules 1", drupe 3"' long- Hab. Jamaica !, 

 Dancer; Montserrat, Dominica!, Imr., S. Vincent!, Guild.; [French islands !]. 



32. STENOSTOMUM, G, 

 (Laugeria, V., Sw., G., non Jacq.) 



Calyx-limb 5-4-dentate or subtruncate, persistent on the fruit. Corolla salver-shaped : 

 lobes 5-4, short, imbricative. Anthers linear, subsessile below the corolla-throat, included 

 or half-exserted. Stigma capitate. Drupe 2-6-celled: endocarp-cells as narrow as the 

 cylindrical seeds. — Woody plants ; inflorescence of Guettarda. 



The only difference between Stenostemum and Guettarda results from the calyx-limb 

 crowning the fruit in the former, though in the latter genus it be often tardily deciduous. 

 The testa (Gsertner's albumen) is rather more tumid in Stenostomum ; but this is only a cha- 

 racter of degree. Gsertner's analysis of Laugeria (in contradistinction of Stenostomum), viz. 

 a minute embryo in the axis of albumen in S. resinosum, is probably erroneous, as in my 

 nearly allied S. viscosum I find the operculum-like arillus and long embryo of Gueltardea ■-, 

 as figured by Gaertner in his S. lucidum. 



Sect. 1. Eustknostomum. — Ovary 2(-4)-celled. Flowers ebracteate. Stipules deciduous. 

 — Trees, devoid of resinous excretions.

 and their axils beneath ■. stipules ovate-oblong; peduncles 2-fid above the middle : branches 

 recurved : flowers approximate ; calyx oblong, sericeous : limb tubular, obsoletely 5-Iobed- 

 repand ; corolla-tube clavate (3'" long), strigose : lobes 5, glabrous within ; anthers in- 

 cluded; drupe oblong, bluntish. — Malanea, Desr. — A timber-tree; leaves 4"-3" long, ex- 

 ceeding the peduncles ; drupe 4"'-3"' long. — Hab. Jamaica !, Pd., M'Nab, March, in woods, 

 Manchester near Spitzbergen, S. Anns. 



83. S. tomentosum, DC. Leaves elliptical, glabrous above, velvety -tomentose be- 

 neath : primary veins prominulous beneath : stipules lanceolate ; peduncles once or twice

 prominulous beneath: stipules ovate-lanceolate; peduncles once or twice 2-fid about the
