tubuli called dental'ta, and thofe called antalia, differ only in 

 fize ; and lie thinks they have no title to the name concha, 

 fince they are neither of the nature of the common bivalve 

 nor univalve (hells, fuch as the patella and auris marina ; but 

 this is very idle, fince by this rule tlie fnails, and many other 

 families, might be excluded as well as thefe. This author 

 fays, in another place, that the aritak is formed of many 

 circumvolutions ; whence he feems to have taken in the iuc- 

 cina under this name ; but later writers have more nicely dif- 

 tinguifhed in thefe cafes. The fea-pencil is evidently of this 

 genus, though extrrtnely different from all the other fpecies 

 of it, in having its head pierced with a multitude of holes, 

 in the manner of the head of a watering-pot. Some au- 

 thors, from the figure of the fhell, call this phallus marlnus, 

 and the French call it k priape. Aldrovand. de Teliae,

TUBULINA, in Botany, a diminutive, from tubus, a 

 tube, exprefling the ftrufture of the fungus in queilion. — 

 Perf. Syn. Fung. 197. — Clafs and order, Cryplogamia Fungi. 

 Nat. Ord. Fungi. 



Eff. Ch. Receptacles tubular, combined in a tuft, ge- 

 nerally feated on a fubjacent metnbrane. Seeds powdery, 

 naked, farinaceous. 



1. T. frJlax. Doubtful Tubulina. Perf. n. i. Obf. 

 Mycol. fafc. 2. 28. — " Opaque, indeterminate, brownidi. 

 Receptacles combined at the top into an uniform bark." — 

 Found, very rarely, on the trunks of trees. Pcrfoon ap- 

 pears to have examined a fingle fpecimen only, and therefore 

 knew nothing of the appearance of the plant in an early 

 ftage of growth. This fpecimen was about an inch long, 

 various in breadth, of an earthy or rufty colour. The 

 tubes were full of powder, otherwife he would have thought 

 it rather the early Hate of fome Boletus or Sphieria. 



2. T. fragiformis. Strawberry Tubulina. Perf. n. 2. 

 Obf. Mycol. fafc. 2. 29. (Tubulifera arachnoidea ; Jacq. 

 Mifc. Auftr. V. I. 144. t. 15. T. Ceratum ; Fl. Dan. 

 t. 659. f. 2.) — Nearly globular ; firft red ; then brown ; re- 

 ceptacles rather fwclHng upwards, diftinft at the top. — 

 Found on the trunks of trees, after heavy rains in fummer, 

 attrafting notice by its likenefs to a large ilrawberry. 

 When arrived at maturity, it becomes opaque, of a rufl;y 

 brown. The author above quoted mentions in his Obfer-va- 

 tiones Mycologies, fafc. 2, numerous/;;n^( allied to this, partly 

 obferved by himfelf, and partly defcribed by other authors, 

 which he was doubtful whether to confider as fpecies or va- 

 rieties. His doubts fecm to have been rather increafed than 

 diminifhed when he wrote his Synopfis, and therefore we can- 

 not prefume to remove them. Among thefe obfcure pro- 

 duftions are Sphxrocarpus fragiformis, Bulliard t. 384, and 

 5. cylindricus, t. 470. f. 3, which appear to anfwer well to 

 the generic charafter of Tubulina, and to be fpecifically dif- 

 tin6t hom T. fragiformis, as reprefentcd by Jacquin. Per- 

 foon alfo mentions a Relicularia multicapfula of Sowerby's 

 Fungi, t. 169, which is an altogether erroneous reference ; 

 nor fhall we attempt to guefs whether it alludes to any thing 

 in that author's t. 399, or any other. 



TUBULOSE Leaf, among Botanijls. See Leaf. 



TUBURBO, in Geography, a town of Africa, in the 

 kingdom of Tunis, on the Mejerda, fuppofcd to be the 

 ancient 'Tuburbum. Mahomet, a late bey of this kingdom, 

 planted a great number and variety of fruit-trees in the 

 neighbourhood of this town, which were ranged in fo par- 

 ticular a method, that each fpecies was confined to one 

 grove, and thereby removed from all influence of another. 

 Li the adjacent valley, where the Mejerda conveys its 

 ftream, the fame curious and generous prince erefted out of 

 the ruins of a neighbouring amphitheatre, a large maffy

bridge or dam, with proper fluices and flood-gates to raife 

 the river to a convenient height for watering and refrefhing 

 thefe plantations. But this, which was too laudable an in- 

 vention to fubfift long in Barbary, was foon entirely broken 

 down and deftroyed ; 16 miles W.N.W. of Tunis. 



TUBUS CoROLL.'E, in Botany, the inferior, more or lefs 

 cylindrical, part of a monopetalous corolla, fupporting the 

 L1MBU.S ; fee that article. The tube differs in length, in 

 different genera or fpecies of plants, as well as in (hape. A 

 rotate, or wheel-fhaped, corolla lias the tube neccflarily very 

 fhort, or fcarcely any ; a funnel-fhaped one has the fame 

 pai-t elongated, and dilated upward. Sometimes the tube 

 conceals the ftamens, which are inferted either into fome 

 part of itfelf, or more rarely into the receptacle ; fometimes, 

 indeed very frequently, the ftamens projeft, with the ftyle, 

 out of the tube. Its mouth is ufually pervious ; fometimes 

 hairy ; in feveral genera of the tribe Afperifoliic, that part 

 is clofed by arched or converging valves, covering the an- 

 thers. The claws of the petals, in a polypetalous corolla, 

 ftand in the place of the tube of a monopetalous one, and 

 in fome inftances arc fo far connefted, at an early period, as 

 really to conftitute a tube, fubfequently fplitting into claws. 

 Examples occur in the order of Proteaxe,!, which have 

 caufed fome perplexity, and difference of opinion, in the 

 charafters given by different botanills of the plants of that 

 order.

TUCK of a Ship, a name given to that part of the fhip 

 where the ends of the bottom planks are collefted together, 

 immediately under the fteni or counter. When this part, 

 inftead of being incurvated, and forming a convex furface, 

 affumes the fhape of a vertical or oblique plane, it is faid to 

 be fquare ; and a fquare tuck is accordingly terminated 

 above by the wing-tranfom, and below, and on each fide, by 

 the fafhion-pieces. Falconer.
