SCALIA. 533 
solum basin versus subincrassata, basi ipsa vel paulo altius pistillidiis 
sterilibus obsessa, in sicco corrugato-striata. Capsula in pedicello 
plus minus alto suffulta, calyptra duplo brevior, fusiformi-cylindrica, 
flavida rufulave, substantia firma, cellulis tamen solum wnistratis, 
elongatis subrectangularibus (pariete colorato corneo, fibris annulari- 
bus nullis); plerumque follicularis, uno solo latere dehiscens, val- 
vulis ad czeteras stuituras inter se coherentibus. Elateres prelongi 
tenues subobtusi arcte dispiri. Sub capsule apice adveniunt elateres 
pauci, ceteris subbreviores, late monospiri, inter quas alii plurimi 
elateres normaliter dispiri, a pariete jam soluti, intorquati longius 
restant, demum autem omnes decidunt. Sporee minutule, elaterum 
diametrum vix duplo excedentes, subglobose, verruculoso-striate. 
Obs. Caulis subdichotomus, vel saltem ramis omnibus lateralibus, raro 
tamen e foliorum axilla ortis. 
In the European Scalia Hookeri the capsule is sometimes cloven on 
one side only; rarely are all the valves completely separated, but mostly 
remain cohering at the apex even when free elsewhere. The capsule- 
wall consists of a single layer of cells, except at the apex, where an inner 
lining of thin cells is added. Several elaters are attached to this apical 
cupola, but they are equally long and slender as the others; they are 
either monospirous throughout, or dispirous below, but with one thread 
running out at about midway. All the other elaters are dispirous, and 
a good many of them are entangled in the apical elaters, with which 
they persist for a time, but soon fall away along with them.
