Ramuli quadrato-compressi. Folia obovata, apice rotundata basi 
cuneata in petiolum longiusculum contracta, margine angustissime 
revoluta, 6-9 cm. longa, 2,5-4 cm. lata, petiolo 5-8 mm. longo, nervo 
medio valido, utrinque inprimis subtus prominente, lateralibus ad 
20-30 tenuissimis subtus exquisite, suprà immerso-prominulis, oblique 
parallelis (50°-60°), nervo submarginali tenuissimo connexis. 
Epidermidis super: cellule recte delineatæ, tabulares altiusculæ, 
parietibus lateralibus ad parietem externam sat incrassatis, cuticulà 
mediocri v. crassiusculà levi. Epidermidis infer» cellulæ conformes, 
cuticulà tenui levi. Stomata elliptica cellulis epidermidis sæpius multo 
majora, cellulis accessoriis magnis. Hypoderma 1-3-seriatum, cellulis 
tabularibus v. in stratubus 2 inferioribus subcubicis. Mesophyllum 
valde variabile, 0.23 mm. — 0,57 mm. crassum. Cellulæ paliformes ; 
sæpius 2-ordinatim dispositæ, superæ 3-6-plo longiores quam latiores, 
inferæ breviores, ambo tertiam partem mesophylli v. fere dimidium 
mesophyllum implentes. Parenchyma spongiosum nunc molle, nunc 
cellulis subsclerosis insparsis v. sub epidermide infera collectis, punc- 
tatis rigidatum. Nervorum lateralium fasciculi immersi utrinque fibris

secundum annulum suprà complanatum dispositi, fasciculos paucos 
includenies, vaginà fibrosà inclusi et Jaminà fibrosà inclusa sustenti. 
Petioli fasciculus arcuatus, margine involutus, fibris mechanicis desti- 
tutus. Glandulæ canaliformes majusculæ in mesophyllo, nervorumque 
petiolique parenchymate numerosissimæ. Crystalla echinata in meso- 
phyllo nervorumque peliolique parenchymate, sub epidermidibus 
numerosiora. 
Flores (fem.) terni v. (in icone Plumieriana) 6, per paria oppositi, 
amplitudine mediocri, pedunculati. Bracte:e calycinæ 6, 2 superiores 
cæteris multo majores. Sepala 4 decussata. Petala 5 (rarius 4) obovato- 
orbiculata, in unguem latum contracta. Cupula staminodiorum humi- 
lis, margine sinuata sterilis (fide Planch. et Triana) nunc antherarum 
plus minus effætarum vestigia exhibens. Ovarium 6-8-loculare, cupulà 
staminodiali plane velatum, stigmatibus 6-8, obtuse triangularibus, 
radiato-conniventibus eoronatum. Capsula ovata, 6-8-locularis, locu- 
lis oligospermis. Semina arillodio antice fisso involuta, superiora pen- 
dula, inferiora ascendentia. .
