 mediocres. Calyx urceolatus vel turbinatus fere usque ad medium inaequaliter 5-partitus 

 (subbilabiatus), partibus ovatis angusteimbricatis, summa (sepalo 4. respondente) 

 breviore angustiore, coriaceus, utrinque tomentellus, interdum (Ch. villiger, subvilliger) 

 villis (i. e. processibus filiformibus dense pilis 1-cellularibus vestitis) ultra tomentum 

 productis obsitus. Petala 4 (infimi sede intersepalum 3. et 5. vacua), interdum anomale 

 5 — 7, calycem superantia, ovato-, oblongo- vel lineari-spathulata, apice saepius crenulata 

 et corrugata, dorso vel utrinque puberula, intus supra unguem squama obtusa vel 

 acuta erecta vel apice cucullato-deflexa secus medianam inferne vel tota laminae 

 adnata (inde petala ^ bisaccata efficiente) et dorso saepius crista ^ conspicua corni- 

 formi (et ipsa interdum aut laminae aut squamae adnata) in 1 specie tantum (Ch. 

 Klaineanus) fimbriato-biloba instructa aucta. Discus 1 -lateralis, reniformis vel semi- 

 lunaris, inter petala in lobulos tumens, glaber. Stamina 7 — 8 (raro 9 — 11), circa 

 pistillum ad floris marginem inferiorem inserta, inaequilonga (superiora breviora), 

 petala vix superantia (floris $ breviora, antheris sterilibus indehiscentibus); filamenta 

 filiformia, hirtella; antherae oblongae, introrsae, dorso supra basin emarginatam 

 affixae, intus saepius adpresse hispidulae, dorso dilatato glabro interdum cellulis 

 majoribus mucigeris instructo (Ch. strigosus) apice glandulam (ut in Radlkofera et 

 Glossolepide) efficientibus (Ch. sexlocularis, Prieurianus, punctatus, micranthus, Leder- 

 mannii, Klaineanus); pollinis granula trigono-placentiformia, 3-porosa, majuscula. 

 Germen (floris $ rudimentarium) sphaericum vel ovoideum, plerumque 3-lobatum, 

 rarius 5- vel 7 — 8-costatum, 3 — 8-loculare, tomentosum, loculis intus pilosis (Ch. 

 brunneo-tomentosus, Mannii) glabrisve (Ch. setosus, stenophyllus , Gerardii, Gilletii); 

 Stylus subulatus, germine longior, apice stigmatoso clavato ^ sulcato erecto vel curvato; 

 gemmulae in loculis solitariae, oblongae, lateraliter compressae, hilo longitudinali angulo 

 centrali affixae, campylotropae, apotropae, micropyli extrorsum infera. Fructus (in 

 3 tantum speciebus — Ch. setosus, stenophyllus, Mannii — visus) coriaceo-baccatus, 

 suborbicularis, ellipticus vel obcordatus, late 3-lobatus (quasi 3-alatus) vel 5 — 8-costatus, 

 lobis costisve lateraliter compressis interdum cristatis (Ch. stenophyllus), varie vestitis 

 (setoso-hirsutis in Ch. setoso et stenophyllo, granulato-pilosis in Ch. Mannii), sarcocarpio 

 crasso carnoso, endocarpio tenuiter chartaceo laevi glabro vel laxe piloso, siccis in- 

 duratis crustaceis. Semen orbiculare, ellipticum vel obovatum, a lateribus ^ com- 

 pressum, hilo lineari ad marginem interiorem longitudinaliter affixum; testa coriacea, 

 brunnea, cellulis superficialibus magnis collapsis et impressis scrobiculata, interdum 

 in utroque latere sulco longitudinali cotyledonum marginibus respondente notata. 

 Embryo erectus, parum curvatus; cotyledones lateraliter compressae, altera dorsali 

 longitudinaliter paullulum incurvata alteri ventrali arcte applicata, amyli granulis 

 parvis farctae; radicula infera, minima, punctiformis. 



Frutices vel arbores parvae, habitu palmarum, trunco simplici vel pauciramoso 

 apice folia rosulatim conferta gerente. Folia alterna, paripinnata, 5 — 8-juga, petiolata 

 exstipulata; foliola saepius magna, deorsum decrescentia, opposita vel subopposita, 

 breviter petiolata, oblonga vel cuneata, acuminata, chartacea, pinnatinervia, nervo 

 mediano supra impresso applanato (setulis tantum secus lineam medianam coacervatis 

 costulam prominulam mentientibus) subtus nervisque lateralibus prominentibus, glabra 

 vel subtus praesertim ad nervös (ut et rhachis) pilosa vel setosa, pilis saepius minutim 

 subulatis inter epidermidis cellulas stellatim dispositas basi paullum dilatata insertis
