4. Loranthus Nigritanus, Hook. fil. ; ramis ferrugineo-villosis, 
folis ovali-ellipticis oblongis sublanceolatisve supra glabris 
subtus ferrugineo-tomentosis, peduneulis brevissimis umbel- 
latim 3-5-floris, bracteis orbiculatis patentibus ovario lon-

Ramuli teretes v. ad nodos leviter compressi, tomento sub- 
floccoso rubro-ferrugineo vestiti, novelli pilis longioribus vil- 
losi; rami vetustiores denudati. Folia 14-2-pollicaria, cras- 
siuscule membranacea, novella utrinque tomentosa, adulta 
supra glabrata, subtus tomento subfloccoso ferruginea. Flores 
fere sessiles, in axillis congesti, pilis longis rubro-ferruginels 
dense vestiti. Bractee exteriores 2 lin. late, crassiuscule, 
undulate, patentes, orbiculate, basi angustate, interiores 
minores angustiores apice breviter patentes. Calyx 1; ln.

quam ovarium longiore. Corolla 15-16 lin. longa, supra 
calycem inflata, dein abrupte contracta, fere ad medium fissa,

The ovary of this species is similar in general structure to 
those described by Griffith, in his paper on Loranthus and

enclosed within the calyx, appears to be free from it, excepting 
in a transverse line a little below the top, corresponding with 
the commencement of the epigynous dise, common to so many 
calyciflorous Orders,
