PROF. OLIVER ON FOUR NEW GENERA OF PLANTS 
attingentibus, stylo filiformi, stigmate minuto; ovula in quoque 
loculo ad 6, ab apice centrali pendula. Fructus ellipsoideus v. ob- 
longus, pericarpio crustaceo v. sublignoso, unilocularis, monospermus. 
— Arbor glaberrima. Folia alterna integra coriacea. Flores pedicellati 
in fasciculos umbellulatos ssepius paucifloros dispositi.

R. CORIACEUM, sp. unica. Arbor 30-pedalis, ramulis teretibus lineis 
brevibus parum elevatis a basi foliorum decurrentibus utrinque notatis. 
Folia breviter petiolata elliptica v. ovato-elliptica, sæpe obtuse et 
breviter apiculata basi rotundata v. subacutata, utrinque glabra, 
31-5! poll. longa, 11-22 poll. lata, petiolus 1-3 lin. longus. Flores 
sepe paulo supraaxillares, pedicellis gracilibus, alabastra 3-4 lin. 
longa, ovoideo-oblonga, subacuta. Fructus (indehiscens, an sub- 
drupaceus?) 9-10 lin. longus. 
Hab. Fernando Po, Mr. Gustav Munn, 1862. Old Calabar, Rev. WAG: 
Thomson, who describes the corolla as pink and white. 
LEPTOCLADUS. 
LoGANIACEARUM genus novum. 
CHAR. GEN.— Calyx persistens parvus 4-5-fidus. Corolla hypogyna, 
tubulari-infundibuliformis, limbi laeiniis 4-5 brevibus, obtusis, eestiva- 
tione imbricatis. Stamina 4 v. 5 imo coroll tubo inserta, inclusa ; 
filamentis lineari-subulatis ; antheris bilocularibus, loculis basi leviter 
divergentibus, longitudinaliter dehiseentibus. Ovarium biloeulare ; 
stylo filiformi; stigmate bifido, lobis bipartitis lineari-filiformibus, re- 
volutis; ovulis in loculis geminatis adscendentibus collateralibus. 
Fructus (imm&turus) coriaceus, compressus, late obcordatus v. bilobus, 
lobis subinzequalibus obtusis monospermis (an interdum dispermis ?). 
Semina compressa lateribus pilosulis margine glabris (an maturitate 
subalatis?).—Frutex, ramulis strictis gracilibus. Folia opposita, in- 
tegerrima, petiolata; stipulis interpetiolaribus minutis. Flores parv! 
in panieulas paucifloras axillares v. terminales dispositi; bracteolis 
obsoletis.

L. THOMSONI, sp. unica. Ramuli novelli puberuli. Folia lanceolata 
utrinque attenuata v. ovato-lanceolata, petiolata, obtusa v. obtusius- 
cula, minutissime mucronulata, glabra. Paniculæ gracile pedunculate, 
folio spe breviores v. interdum longiores. 
Folia: lamina 8-15 lin. longa, 3-6 lin. lata, petiolo 1-14 lin. longo. 
Flores 2-3 lin. longi. 
Hab. Oid Calabar, Rev. W. C. Thomson, who states that the corolla is 
- 
yellow with a white limb. When dry the corolla is reddish.
