CONSPECTUS AND ENUMERATION OF THE SPECIES. 



I. Thyesosma, n. sect. 



Leaves entire or dentate, without stipules; corymbs paniculate, with opposite ramifications; drupe ovoid to ellipsoid, bluish 



black or purple; stone slightly compressed, with a deep ventral furrow; albumen ruminate or solid; easily distinguished from 



the other sections by its paniculate inflorescence; the ruminate and also deeply furrowed albumen occurs also in the section 



Pseudotinus (Thyrsosma, Rafinesque, Sylva Telluriana, 130 [1838]). 



Stamens inserted at varying heights in the elongated corolla-tube; flowers appearing before the leaves; leaves deciduous, serrate, 

 with straight veins. 



Leaves pubescent on the veins beneath; panicles many-flowered. 1. V. fragrans. 



Leaves glabrous beneath; panicles few-flowered. 2. V. nervosum. 



Stamens inserted at the same height; flowers appearing after the leaves. 

 Corolla rotate or campanulate-rotate. 



Albumen not ruminate; leaves serrate, with straight or slightly anastomosing veins. 



Leaves rounded at the apex, with the veins ending in the teeth, usually stellate-pube 

 Leaves with five or six pairs of veins, from 4 to 6 centimetres long; panicles fasci 



branchlets. 3. V. yunnanense. 



Leaves with from eight to twelve pairs of veins, from 6 to 12 centimetres long; panicles nearly glabrous, on 

 four or six-leaved branchlets. 4. V. Sieboldii. 



Leaves acute or acuminate, with often slightly anastomosing veins, glabrous; panicles glabrous. 



5. V. Henryi. 

 Albumen slightly ruminate; leaves entire or serrulate, with anastomosing veins, glabrous. 



Panicles large and broad, glabrous; leaves entire or with a few blunt teeth, bluntly acuminate, large, persistent.

Panicles narrow, and together with the peduncles scarcely exceeding 5 centimetres in length, pubescent; leaves 

 serrate or entire, acuminate. 7. V. brachybotryum. 



Corolla infundibuliform. 



Leaves acuminate, serrate, deciduous; panicles slender. 



Panicles many-flowered ; leaves membranaceous, mostly oval, serrate, with spreading teeth and partly straight veins, 



8. V. ucntom. 



Panicles few-flowered; leaves chartaceous, generally elliptic-lanceolate, sharply serrate, with incurved teeth and
