Zwei Beiträge zur Systematik der Solanaceen. 259 



Am Schlüsse der zweiten Mittheilung angelangt fasse ich die Er- 

 gebnisse meiner Untersuchung mit den Angaben von LINDEN und 

 PLANCHON, wie DRAKE DEL CASTILLO in Form von Diagnosen von 

 Trianaea und ihren zwei Arten zusammen. 



T}'ianaea\j\n^. etPlanch., in LINDEN, Prix-courant 1853 und 

 Bot. Zeit. 1853, S. 718- 719 (Syn.: Poortmannia Drake del Castillo, 

 in Bull, de la Soc. philomat. de Paris, Ser. 8, T. IV, n. 3, 1892, 

 p. 128 — 129 et pl. I). Calyx amplus, campanulatus, alte 5-fidus, lobis 

 foliaceis trinerviis, valvato-reduplicatis, basi connatis. CoroUa calycis 

 lobos pauUo superaus, ample campanulata, prope basin in tubum bre- 

 vem et latum contracta, lobis 5 apice rotundatis, quincuncialiter imbri- 

 Catis, sinubus inter lobos (semper?, certe in Tr. speciosa) induplicatis, 

 petalis atque lobis trinerviis. Stamina 5 supra basin contractara co- 

 rollae inserta, breviter exserta, coroUae lobis alterna, filamentis longis, 

 apice tenuibus et gracilibus, antheris longis, 1 cm superantibus, basi 

 vel prope basin affixis, endothecio (in Tr. speciosa) 2 — pluriseriato. 

 Pollen (in Tr. speciosa) globosura, extus minute et irregulariter reti- 

 culatum. Discus carnosus subannularis, aequaliter 5-lobus. Germen 

 (Fig. 2A) 5-carpicum, septis spuriis (semper?) perfecte 10-locellatum; 

 gemmulae in loculis numerosae, dissepimentis falsis afßxae; Stylus 

 longus, apice clavatus et 5-sulcatus, lobis 5 conniventibus. Fructus 

 ignoti. 



Frutices fasciculis vascularibus bicollateralibus, ligno moUi, vasis 

 simpliciter perforatis, prosenchymate punctis simplicibus notato. Folia 

 alterna, majora, petiolata, oblonga, utrinque acuta, integerrima, mar- 

 gine plus minusve revoluta, coriacea, glabra nee nisi glandulis micro- 

 scopicis, stipitibus 1 — 2-cellularibus brevibus et capitulis oblongis hori- 

 zontaliter et verticaliter partitis instructis, obsita, penninervia, et nervo 

 mediano et nervis paucis secundariis, alternantibus, circa 5 — 6 in utro- 

 que latere, subtus prominentibus, venis inconspicuis; mesophyllum 

 cellulas sclerenchymaticas inprimis in tela spongiiformi continens, epi- 

 dermis utraque parietibus exterioribus crassis instructa, fasciculi nervo- 

 rum bicollaterales, fibris sclerenchymaticis circuradati, stomata modo in 

 inferiore foliorum pagina explicata, plerumque cellulis 3 accessoriis cir- 

 cumdata, magna, extus insigniter punctata (Fig. 3). Ramorum et folio- 

 rum parenchyma et phloema interius atque exterius fasciculorum vas- 

 cularium utriculos calcii oxalici repletos fovens. Cymae 2 — 3-florae 

 vel flores solitarii, pedicellis longis. Flores speciosi, perianthio (co- 

 rolla et calyce) floribus Cobaeae persimiles. 



Genus et germine et corollae forma insigne. Species 2, 

 Andium Ecuadorensium incolae.
