226 SOLANACE^. Lycopersicum. 



bryo either straight or only slightly curved ; the cotyledons usually broader than 

 the radicle. 



13. OESTRUM. Corolla salverforra or tubular-funnelf orm ; the short lobes induplicate- 

 valvate in the bud. Filaments filiform : anthers short, explanate after dehiscence. 

 Ovary usually short-stipitate, few-ovuled. Fruit' a rather dry globular berry. Seeds 

 few, or by abortion solitary, with a smooth testa : cotyledons usually broad and flat. 



14. NICOTIANA. Corolla funnelform or salverform, phcate and somewhat imbricate in 

 the bud. Filaments filiform, mostly included : anthers ovate or oblong, often explanate 

 after dehiscence. Ovary normally 2-celled, with large and thick placentae, bearing very 

 numerous ovules and seeds. Style filiform : stigma depressed-capitate and often 2-lobed. 

 Fruit a capsule, more or less invested by the persistent calyx, septicidal and also usually 

 loculicidal at summit ; the valves or teeth thus becoming twice as many as the cells, i.e. 

 usually 4. Seeds very small, with granulate or rugose-f oveolate testa : cotyledons little 

 broader than the radicle. 



Tribe V. SALPIGLOSSIDE^. Corolla with lobes (either regular or somewhat 

 irregular) plicate or iuduplicate and also more or less bilabiately imbricated , the two 

 superior external. Stamens 5, conspicuously unequal, four being didynamous and 

 the fifth smaller, the latter (and even one pair of the others) sometimes imperfect 

 or abortive. Seeds globular or angular, not compressed. Embryo curved or nearly 

 straight, with cotyledons usually broader than the radicle. (Transition to Scrophula- 

 riacea.) 



* Stamens all five perfect (or rarely the fifth wanting), inserted low down on the funnel- 

 form or salverform corolla, included. 



15. PETUNIA. Calyx 5-parted. Anther-cells distinct. Hypogynous disk fleshy. Stigma 

 dilated-capitate, unappendaged. Capsule with 2 undivided valves, parallel with and sepa- 

 rating from the placentiferous dissepiment. 



1 6. BOUCHETIA. Calyx oblong-campanulate, 5-cleft, with narrow lobes. Corolla short- 

 funnelform. Anthers connivent ; their cells somewhat confluent at summit. Hypogy- 

 nous disk none or obscure. Stigma transversely dilated, somewhat reniform. Capsule 

 at length 4 valved. Seed-coat minutely reticulated. 



# # Stamens 4, didynamous, the fifth a sterile filament, included in the throat of the long- 

 tubed corolla. 



17. LEPTOGLOSSIS. Calyx 5-cleft or 5-toothed. Corolla salverform, with slender 

 tube and more or less gibbous ventricose throat, at base of which the stamens are in- 

 serted. Anthers somewhat reniform, confluent at summit; the upper pair much smaller, 

 sometimes imperfect. Stigma or the style under it petaloid-dilated. Capsule membra- 

 naceous, 2-valved ; the valves at length 2-cleft. 



1. LYC0P£:RSICUM, Toum. ToJiATO, &c. (Jixog, wolf, negaixov, 

 peach.) — Chiefly annuals, natives of the warmer parts of America ; with once 

 or twice pinnate leaves, rounded petiolulate leaflets, racemes (so called) of small 

 flowers becoming lateral or opposite the leaves, articulated pedicels reflexed in 

 fruit, and red or yellow pulpy berries, in cultivation esculent and often becoming 

 several-celled. 



L. EscuLENTHM, Mill., var. cekasif6rme. (CHERRT-To>rAT0.) Annual, hirsute on the 

 branches and more or less glandular : leaves interruptedly 1-2-pinnate ; the larger leaflets 

 incised and toothed, the interposed small ones rounder and often entire : calyx little shorter 

 than the yellow corolla : inflorescence bractless : berry globose and even, small. — L. cerasi- 

 forme, Dunal. Solarium Lycopersicum, var., L. S. Pseudo-Lycoperskum, Jacq. Vind. t. 11. — 

 The normal form, probably, of the Tomato of the gardens : spontaneous on the southern 

 borders of Texas {Berlandier, &c.} : introduced from Trop. Amer. 



2. SOLANUM, Tourn. Nightshade, &c. (Late Latin name of Night- 

 shade, probably from solamen, solace.) — Herbs or sometimes shrubs, of various 

 habit ; with the leaves (as in many other genera of the order) often geminate, 

 the proper leaf being accompanied by a smaller lateral or extra-axillary (rameal)
