Mr. J. Miers on the genus Lycium. 7 



and diameter to the cotyledons, points to the basal angle of the 

 seed at some distance from the lateral hilum, which is situated 

 in a conspicuous sinus on the ventral margin. The following is 

 oiFered as a more exact expression of its generic features than 

 that given in the ' Prodromus ' referred to. 



Lycium, Linn.; DC. Prodr. xiii. 508 (char, emend.). — Calyx 

 tubuloso-campanulatus, 5-dentatus, vel sub-5-fidus, dentibus 

 saepe irregularibus vel aliquantulum confluentibus, persistens. 

 Corolla tubulosa vel infundibuliformis, tubo imo constricto 

 et hinc demum circumscisso, limbo 5- rarius 4-fido, laciniis 

 rotundatis vel oblongis, obtusis, tubo brevioribus aut lon- 

 gioribus, reflexis, sestivatione valde imbricatis, lateribus sese 

 ample tegentibus. Stamina 5, rarius 4, laciniis alterna, ssepe 

 insequalia, medio vel supra basin tubi inserta, longitudine 

 corollse aut breviora; filamenta filiformia, glabra, vel supra 

 insertionem semper geniculatam interdum barbata, saepe lon- 

 gius hirsuta, aut ad basin glandula lineari antice sita, margine 

 ciliata donata ; anthera oblongse, 2-loculares, loculis adnatis, 

 sequaliter 2-valvatis, rima longitudinali margine dehiscentibus. 

 Pollen globosum longitudinaliter 3-sulcatum. Ovarium brevi- 

 ter stipitatum, oblongum, imo disco carnoso adnato ssepissime 

 fere obsoleto et cupula libera (corollse reliquo) circumdatum, 

 2-loculare, placentis dissepimento coadunatis, multiovulatis. 

 Stylus simplex, staminibus subsequilongus, apice paullo in- 

 crassatus. Stigma depresso-capitatum, plus minusve 2-lobum. 

 Bacca calyce ssepe irregulariter fisso suffulta, globosa, aut 

 ovata, 2-locularis. Semina plurima, compressa, reniformia; 

 testa scrobiculata, Crustacea; embryo intra albumen carnosum, 

 helico-spiralis, teres, radicula augulo basali spectante, hiloque 

 marginali evitante, cotyledonibus semiteretibus aequilonga. — 

 Arbusculse vel frutices scepius spinosi, prcesertim in America et 

 Africa, pauci in Europa australi et Asia crescentes', folia alterna, 

 integra, scBpissime e gemmis foliaceis axillaribus fasciculata ; 

 flores pedunculati, solitarii, gemini, vel aggregati, axillares, vel 

 scepius e gemmulis foliaceis in spinis sistentes, aut rarius ex ax- 

 illis approximatis pseudo-terminales ; corollae albida,flavescentes, 

 rosece, vel coccinece. 



1 . Brachycope. Corolla fere cylindrica, interdum paullo ventri- 

 cosa, limbi laciniis parvulis, tubi dimidio longitudine, vel adhuc 

 scepius brevioribus.
