 enkelte Firlinger, som findes, er den ene Form 0.092""" lang.

den anden er meget rig paa Takker. Fig. 55. omtrent lige

 Firlinger, der rindes paa Basaldelen, Fig. 29. 



Paa Grenene træffes hyppigst Klubber, kun sjeldent en 

 Firling og en enkelt, stilket, tr.earmet Stjerne, samt en 

 monstrøs Dobbeltstjerne. Klubberne ere dels takkede, 

 dels bladede med takket Skaft; de ere fra 0.116—0.142""" 

 lange og fra 0.040—0:056""" brede i den tykke Ende.

Overalt i Coenenehymet tindes udbredte Spikel- 

 afleiringer. Det er i Skillevæggene langs de store Saft- 

 kanaler, Spiklerne ere afsatte, og her ligge de som oftest 

 i Rækker nærmest Epithelialbeklædningen, Fig. 20. c. 

 Det Epithel, der beklæder Saftkanalerne, dannes som tid- 

 ligere omtalt af nogle aflange Celler, som stundom antager 

 Ellipseformen. have en stor Kjerne og ere sandsynligvis 

 en noset omdannet Form af Ectodermcellerne. 



I Coenenehymet nederst paa Stammen ere Firlinger 

 og takkede Spindler almindeligst, imellem dem tindes 

 enkeltvis gaffelforniede Klubber, samt monstrøse Dobbelt- 

 stjerner. Firlingerne ere meget forskjellige, men de fleste 

 nærme sig dog mere eller mindre Korsformen og ere be- 

 satte snart med Vorter, snart med Takker; deres Længde- 

 stok er fra 0.120—0.148' lang og Tverstok fra 0.088—

 yderst sjeldne, have Timeglasformen, ere mest en glatte. 0.068"""

The bistellates have foliated ravs and a bare mesial stripe; 

 they measure from 0.084""" in length. 0.056""" in breadth 

 at tlie extremities. aud 0.020""" in breadth at the middle 

 (Pl. XV, fig. 45). The fusees are, frequently, strongly 

 spicate, and pretty niuch dilated in the middle; they 

 measure from 0.080 — 0.144""" in length, and from 0.028 

 —0.048"-"' in breadth (Pl. XV. figs. 46. 48). The clav- 

 ates are spicate almost right down to the extremity of 

 the shaft; they measure from 0.080—0.132""" in length. 

 and from 0.040—0.064""" in breadth at the thick extre- 

 mity (Pl. XV. figs. 49 — 52). The subclavates are narrow, 

 and measure 0.104""" m length. and 0.036""" in breadth 

 at the thick extremity : their shaft is pretty long, and 

 sparingly beset with spikes (Pl. XV, fig. 53). Of the 

 few quadruplets which are found, the one form measures 

 0.092""" in length. and 0.060""" in breadth. and is only 

 sparingly supplied with spikes (Pl. XV. fig. 54). The 

 other form is very rich in spikes (Pl. XV, fig. 55 1 : it 

 measures about the same in length as in breadth. and 

 approaches, much, in form to a few cruciform quadruplets 

 that are found in the basal part (Pl. XV, fig. 29). 



On the branches, clavates are most frequently met 

 with; only rarely is a quadruplet and a solitary pedunculated 

 bhree-rayed stellate met with, also an immense bistellate. 

 The clavates are, partly. spicate, partly foliate, with a 

 spicate shaft; they measure from 0.116 — 0.142""" in length, 

 and from 0.040— 0.056""" in breadth at the thick extremity 

 (Pl. XV, figs. 56—60). The quadruplet forms a beautifully 

 embellished crucitix. with a longitudinal arm measuring 

 0.132""" in length. and a transversal arm measuring 0.064""" 

 in length (Pl. XV, fig. 61). The pedunculated three-rayed 

 stellate is about as long as it is broad (Pl. XV, fig. 62). 

 The bistellate measures 0.072""» in length, 0.040""" in 

 breadth at the extremities. and 0.012" 1 in breadth at 

 the middle (Pl. XV. fig. 63) 



Everywhere, in the sarcosoma. spicular deposits are 

 found spread out. It is in the divisional walls along the 

 course of the large nutritory ducts that the spicules are 

 deposited, and they are. there, most frequently. situated in 

 series next the epithelial covering (Pl. XV, fig. 20. a). 

 The epithelium which clothes the nutritory ducts is for- 

 med. as previously spoken of. of somewhat oblong cells 

 which. sometimes, assume elliptic form and contain a 

 large nucleus ; they are probably a somewhat altered form 

 of the cells of the ectoderm. 



In the sarcosoma. lowest down on the stem, quad- 

 ruplets and spicate fusees are commonest; between them, 

 occasional furcate clavates are found. also immense bistel- 

 lates. The quadruplets are very various. but most of 

 them, however. approach more or less to the cruci-form. 

 and are beset, sometimes, with warts, sometimes with 

 spikes. Their longitudinal arm measures from 0.120 — 

 0.148"'"' in length. and their transversal arm from 0.088 — 

 0.148""" in length (Pl. XV. figs. 64—67). A few quad- 

 ruplets, but they are very rare however. have the sand- 

 glass form, and are almost smooth; they measure 0.068'"™ 

 in length. 0.044""" in breadth at the extremities. and
