Plantae cubenses Ekman. II 239 
Plumeria dietyophylla Urb. (spec. nov.). Rami minutissime 
patenti-pilosi, eicatrieibus foliorum delapsorum ratione valde (0,7—1 cm. 
longe) inter sese distantibus hippocrepiformi-prominentibus obsiti, ad 
apicem biramosi. Folia 1,5 — 2,5 cm. longe petiolata, oblongo-cuneata, 
fere ab apice ad basin versus sensim in petiolum angustata, antice 
truncata v. rotundato-subtruncata, integra, 10—14 cm. longa, antice 
2—2,5 cm. lata, secus nervum medium sulcata, nervo ipso in sulco 
plus minus prominulo, lateralibus utroque latere 25—30 sub angulo 
er. 80° abeuntibus, supra impressis, subtus crassiuscule prominentibus 
reticulato-prominenti-anastomosantibus et er. 1 mm. ante marginem 
nervo longitrorso crassiore conjunctis, ad petiolum et subtus ad nervum 
medium minute pilosula, caeterum glabra pergamacea, margine plana 
v. vix recurva, supra in sicco nigrescentia nitida, subtus brunescentia. 
Inflorescentiae terminales, pedunculis 12 cm. longis, 4 mm. crassis minu- 
tissime pilosulis, 3-radiatae, ramis er. 2,5 cm. longis bifureis; bracteae 
semilunares; pedicelli 3--6 mm. longi, apice incrassati. Calyx 1,3 mm 
longus eupuliformis; lobi perbreves vix semilunati v. subtruncati. Co- 
rolla 23— 32 mm. longa glabra; tubus (coctus) medio 1,2 mm. latus; lobi 
tubo dimidio longiores obovato-elliptiei, antice rotundati 7—8 mm. ati.

Obs. I. Verisimiliter affinis P. venosae Britton, quae e descriptione 
foliis apice obtusis v. emarginatis, pedicellis 8S—15 mm. longis, calyce 3 mm. 
longo, corollae lobis anguste oblongo-oblanceolatis gaudet. - 
Obs. II. Sub P. emarginata Griseb. (Wright n. 2951) folia inveni, quae 
ad speciem nostram arcte accedunt, sed er. 3,5 mm. lata, inferne minus 
sensim angustata, nervo marginali margini ipsi valde approximato sunt. 
Plumeria Ekmanii Urb. (spec. nov.). Glaberrima. Folia ad api- 
cem rami 2—10 mm. longe inter sese distantia, 1—1,5 cm. longe petio- 
lata, obovato-cuneata, in ?/, inferiore sensim angustata basi acuta, an- 
tice rotundata v. subtruncata non emarginata, 9—16 em. longa, 3—5 em. 
lata, nervo medio supra leviter impresso, subtus erasse prominente, late- 
ralibus utroque latere er. 15 sub angulo 85— 90° abeuntibus ideoque 
subhorizontalibus, supra tenuiter impressis, subtus tenuiter prominulis 
non anastomosantibus, 1 mm. ante marginem longitrorsum conjunctis, 
margine albescente angustissime revoluta, pergamacea, supra in sicco 
nigrescentia, subtus brunescentia. Inflorescentiae terminales, pedunculo 
11 cm. longo, 2,5 mm. erasso, pluriradiatae breviter subeorymbosae multi- 
florae, cr. 3,5 cm. longae; bracteae late triangulares v. semilunatae; 
pedicelli 7—9 mm. longi apice incrassati. Sepala libera parum imbri- 
cata semilunaria v. vix semiorbieularia, er. 0,5 mm. longa. Corolla 
18 mm. longa; tubus 6 mm. longus inferne 1,5 mm. crassus, supra
