10 Dr. B. Seemann on Hanburia, 
branaccous epidermis, and resembling altogether so much those 
of Fevillea that I suggested they might possibly belong to that 
genus. Mr. Schaffner, on being informed of this suggestion, 
replied that he could not agree with me, as the complete speci- 
mens at his disposal enabled him to pronounce the Chayotilla a 
representative of a new and remarkable genus, differing from 
Fevillea by its setose-echinate fruit, and other characters. In 
order to convince me, he enclosed in a letter to our friend Mr. 
Scheer, of Northfleet, a fragment of the plant in question, after- 
wards presented by me to Sir W. J. Hooker’s herbarium. This 
fragment, of which Mr. Fitch made a characteristic drawing, 
shortly to be published in the ‘ Bonplandia, was carefuily exa- 
mined and compared with all the Cucurbitacee in Sir William 
J. Hooker’s and other large herbaria; but neither there nor in 
any published description or figure did I find any type approach- 
ing that of Schaffner’s remarkable plant. I therefore assumed 
it to be quite a new genus, and seized the opportunity of con- 
ferring upon it, in honour of my esteemed friend Daniel Han- 
bury, Hsq., F.L.S8., the name of “ Hanburia,’ in a paper read, 
July 1, 1858, before the Linnean Society, and published, on the 
15th of August of the same year, in the ‘ Bonplandia’ (vol. vi. 
p: 298). Owing to the imperfect materials at my disposal, the 
gerieric character I was able to furnish remained in several 
particulars incomplete. This defect I am now able to remedy in 
some measure ; for, shortly after the publication of my paper, two 
drawings, accompanied by a fair account of the plant, and ad- 
dressed, as far back as 1850, by M. Hugo Fink, of Cordova, Mexico, 
to Sir William J. Hooker, were found at Kew, and kindly placed 
by Sir William at my disposal. M. Fink, avowing himself a 
self-taught botanist, and claiming indulgence if he should have 
used any unbotanical expressions, furnishes the following ac- 
count, of which I have given an abstract in ‘ Bonplandia? (vii. 
p: 2) — 
‘A perennial plant; roots not yet examined. Stem pentagonal, 
solid and very fibrous, tough (so that probably ropes might be 
manufactured from its fibres); climbing by means of tendrils to the 
height of from 60 to 80 feet, covering entire trees. As soon as the 
plant has attained the summit of a tree, the branches grow down- 
wards, exactly as in Vanilla or Begonia scandens. Leaves cordate, 
smooth and glossy, on a long petiole, turning different ways. Flowers 
white, axillary and terminal, bell-shaped ; corolla five-parted ; calyx 
in five divisions, covering half the tube of the corolla, and termi- 
nating at each intersection of the corolla in a very small tooth. 
Stamens united in a hollow tube, terminating in a pentagonal, solid, 
almost round ball, having the form of the clapper of a bell. This 
ball, forming the anthers, is divided into five divisions, each of which
