 ventute solum parce et minuti.ssime puberuli) , secus basin foliorum loco squamis 

 membranaceis minutis acuminatis instructi; rami sparsi vel subfasciculati simplices

 tunda vel ovato-subrotunda, excepto petiolo glaberrima, margine subcartilagineo in- 

 tegerrima et plana, radicalia nulla, caulina et ramealia majora — 9 lineas longa, ra- 

 mularia minora, petiolus 1 — 2 lin. longus , minutissime hirtellus (sub lente), hasi in 

 vaginulam amplexicaulem dilatatus, supra concavus. Flores solitarii breviter pedun- 

 culati, in quovis ramo pauci ; pedunculus crassiusculus cum flore continuus curvus 

 verisimiliter ascendens. Perianthium I^^ — 2 pollices longum, livide violaceum gla- 

 brum nervosum subreticulatum marcescens , tubus e ventricosa basi subcylindraceus 

 magis miuusve arcuatus, fauce parum dilatatus et antice in dentem acutiusculum pro- 

 ductus, limbus oblongoliguliformis obtusissimus rectus , sub anthesi planiusculus, 

 tubo subtriente longior. Ovarium globosum. Gynostemium propter florum nimiam 

 compressionem scrutari non licuit. F^ructus ? 2j. — Crescit in insula Chio. 



2. A. TOURNEFORTII Jaub. & Spacli \. c. tab. 12S. — Planta prostrata vel decurabens 

 glabriuscula pluricaulis perennis. Radix perpendicularis carnosa corticata crassitie 

 digiti (pars superior sola subest in speciminibus obviis). Caules % — 1-pedales sub- 

 filiformes flexuosi flaccidi , magis minusve ramosi angulati virides giaberrimi vel suh 

 lente parce et minutissinie hirtelli, foliati, secus basin foliorum loco squamis paucis 

 membranaceis instructi ; rami simplices vel subpaniculati , cauli simlles et paulo te- 

 nuiores , plerique florigeri. Folia alterna disticha crassiuscula glaucescentia venosa 

 reticulata, breviter petiolata retusa vel emarginata apiculata e basi cordata vel reni- 

 formi in petiolum decurrente suborbitularia vel ovalia vel subovata glaberrima (ex- 

 cepto petiolo plerumque sub lente minutissime hirtello), margine subcartilagineo plano 

 integerrirao , radicalia nulla, caulina inSma minima vel ad squamulas membranaceas 

 sessiles reducta, sequentia gradatim majora (14 — 1 pollicem longa) , petiolus 1 — 2 

 lineas longus, basi in vaginulam amplexicaulem dilatatus, supra concavus. Flores axil- 

 lares solitarii breviter pedunculati, in singulis ramis pauci, dimensione sat variabiles. 

 Pedunculus petiolo subaequilongus, cum flore continuus arcuatus (verisimiliter assur- 

 gens). Perianthium olivaceum vel livide violaceum glabrum nervosum subreticnlatum 

 sub anthesi magis minusve curvum, 6—15 lineas longum , tubus e basi globoso-ven- 

 tricosa subcylindraceus arcuatus , fauce subampliatus et antice in denticulum acutum 

 productus, limbo plerumque paulo brevior, limbus lineari-oblongus vel lineari-lanceo- 

 latus acuminulatus, 1—2 lineas latus, 3—7 lineas longus, nunc rectus, nunc subtortus. 

 Ovarium globosum glabrum. Gynostemium propter niraiam compressionem scrutari 

 non licuit. Fructus immaturus globosus vel subpyriformis. — Crescit in insula Chio 

 nec non in Troade.
