Were further proof of a lateral connexion necessary, the fact that 

 the filaments, when not in contact with any other body, are found thus 

 attached to each other, might supply it : in the species most thorough- 

 ly adnate they frequently adhere throughout their whole length ; (see 

 d, e, fig. 1). 



No. II. — Filaments spreading irregularly, adhering at intervals, horny, smooth, dis- 

 tinctly tubular, and divided by septa, from which are produced the hemispheri- 

 cal buds of the branches ? (</) : branches nearly at a right angle. Of a rich brown 

 colour. (Fig. 2,/, g, m, n, o ; Fig. 3, x, y). 



Found in moderate quantities on most of the portions examined, 

 exterior to the other species. 



No. III. — Filaments agglutinated or interwoven together, pellucid, with slight traces 

 of a cellular structure, rarely dichotomously branched ; accompanied by numer- 

 ous subspherical tuberculated or granulated bodies (sporidia ?), which have on 

 their depressed surfaces a circular lucid disk. (Fig. 2, h, i, k, I). 



Found only on a portion of the Southport specimens. 



To Mr. Wilson I am indebted for calling my attention to the 

 spheroidal bodies ; they were not observed during my examination 

 of Southport plants, gathered three weeks after his, and as they are 

 objects far from likely to be overlooked, I suppose they were not pre- 

 sent : the fibre to which they belong was there in abundance. Speci- 

 mens from Southport gathered in 1841, kindly supplied by Mr. Wilson, 

 having the filaments, are likewise without the sporidia. 



All my attempts to discover actual proofs of an organic connexion 

 of these globules with the fibres among which they are found, have 

 been unsuccessful : though from several circumstances observed, such 

 as that the filaments are frequently flattened, and have occasionally in 

 the depressions the appearance of scars (fig. 2, ^), I have little doubt 

 that such does exist, the transparent disks being the point of union. 

 Fragments of one or two other kinds have been met with, but not in 

 quantities to supply the characters for a description. The three given 

 will suffice. 



Such are the data on which I would ground the opinion that the 

 "byssoid substance" is really fungoid, and performs no essential func- 

 tion in the economy of the Monotropa. Each of the operations has 

 been often repeated, with all the care and diligence I could command. 

 Sections in all variety have been viewed, wet, moist and dry, with re- 

 flected and transmitted light; and though the results were in all cases 

 the same, yet it should be stated that those were the most satisfactory 

 in which the portion had been saturated with, and was examined
