HEPTACODroM Rehder, n. gen. 



Calycis tubus turbinatus, dense setosus; lobi 5, oblongi, persistentes, 

 acerescentes; corolla tubuloso-infundibuliformis, tubo leviter curvato 

 basi subaequali; limbus leviter bilabiatus, 5-partitus, lobis oblongis, 

 antico patente v. reflexo, posticis erecto-patentibus; stamina 5, fila- 

 mentis fauci corollae insertis elongatis, antheris oblongis; stylus fiii- 

 formis; ovarium inferior, 3-locularis; loculi duo ovulis pluribus steri- 

 libus instruct!, tertius ovulo solitario fertili, Fructus coriaceus, 

 oblongus, calyce limbo accrescente coronatus, 3-locularis, loculis 

 duobus effoetis compressis, tertio monospermo; semen elongatum basi 

 subcylindrium, supra compressum, testa membranacea, albumine 

 carnoso; embryo brevis cylindricus, in basi seminis. — Frutex erectus, 

 ramulis striatis medullosis, gemmis perulatis. Folia decidua, opposita, 

 petiolata, 3-nervia, Integra; stipulae nullae. Flores albi, sessiles, in 

 capitulis axes primi ad tertii ordinis terminantibus et paniculam ter- 

 minalem erectam formantibus; capitula 7-flora, involucrata, involucro 

 persistente, e bracteolis 10 ovatis dense sericeis in duobus seriebus dis- 

 positis, 4 exterioribus et 6 interioribus, composito et basi bracteis 2 

 majoribus orbiculari-ovatis suffulto, pedunculata pedunculo stricto 

 bracteis parvis 2 v. 4 decussatis instructo. 



Genus novum Aheliae et Lonicerae proxima; ab utroque recedit 

 capitulis 7-floris involucratis, a priore insuper distinguitur staminibus 

 5 fauci corolla insertis, a posteriore ovarii et fructus indole. 



Species unica Chinae centralis incola. 



This genua is very distinct in its general appearance from any other genua of the 

 Caprifoliaceae. In the structure of its flowers it closely resembles Lmiiceraj while 

 in the structure of its ovary and in its fruit it is very near Ahelia. The inflorescence 

 may be compared with the 6-flowered whorls representing two 3-flowered cymes 

 of the section Periclymenum of Lontcera ; if it is assumed that the central axis of 

 these whorls is terminated by a flower, we have the inflorescence of Ileptacodium, 

 and if a species with well-developed bractlets like Lontcera Periclymenum Linnaeua
