A Grammatical Dictionary of Botanical Latin

 
Cystolith, “mineral concretions, usually of calcium carbonate on a cellulose stalk, occurring chiefly in species cells of the Urticaceae, as in Ficus elastica, Roxb.” (Jackson);“a stone-like concretion in the epidermis of some plants, as the Urticaceae and Acanthaceae” (Fernald 1950); “a calcium carbonate concretion commonly stalked and arising from the cellulose wall of certain cells of higher plants, esp. from modified epidermal cells of some flowering plants” (WIII) [> Gk. kystis, a cavity + lithos, stone (Jackson)]: cystolithus,-i (s.m.II), abl. sg. cystolitho; see -lith; see stone-, -stone;

- folia cystolithis supra minutis punctiformibus subtus creberrimis breviter linearibus quaquaversus directis crassiusculis albidis, leaves with cystoliths on upper side minute punctiform on lower side very numerous shortly linear to all directions set rather thick whitish (Stearn).

- [Fleurya] folia alterna, petiolata, dentata, 3-nervia, cystolithis linearibus; (B&H), leaves alternate, petiolate, toothed, 3-nerved, with the cystoliths linear.

- [Neraudia] folia alterna, petiolata, integerrima, 3-nervia, supra interdum creberrime punctulata, cystolithis parum conspicuis (B&H), leaves alternate, petiolate, competely entire, 3-nerved, above sometimes thickly punctulate, with the cystoloths somewhat conspicuous.

- [Thelygonum] Delile l.c. cystolithos in exocarpio observatos descripsit sub nomine aiguilles crystallines (B&H), Delile, l.c. described cystoliths observed in the exocarp under the name aiguilles crystallines.

- plantae cystolithis destitutae, plants lacking cystoliths.

- [Tribe Urticeae] Cystolithi, a Weddellio praecipue commentatae, in hac tribu prae aliis conspicui, in Fleurya et in Procridibuus plurimis lineares sunt, in Myriocarpo insigniter radiantes, in generibus caeteris punctiformes v. hinc inde oblongae v. fusiformes, vix tamen in eodem genere semper conformes (B&H), the cystoliths, especially contemplated by Weddellius, are conspicuous in this tribe compared to others, many are linear in Fleurya and in Procrides, in Myriocarpum remarkably radiating, in the other genera punctiform or here and there oblong or fusiform, yet scarcely always agreeing in the same genus.

NOTE: in one place Bentham and Hooker treat ‘cystolith’ as though a first declension feminine noun, but later and elsewhere as a second declension masculine noun.

 

A work in progress, presently with preliminary A through R, and S, and with S (in part) through Z essentially completed.
