a grain and a nutlet (nut) are similar: [Rumex acetosella] segmentis interioribus nuci subglobosae arcte appressis (B&H), with the inner segments closely appressed to a subglobose nut.

- [Cyperaceae: Psilocarya] nux styli (2-fidi) basi dilatata persistente rostrata (B&H), the grain [i.e. achene] of the style (2-fid) dilated at the base, persistently rostrate.

- (Cyperaceae: Pentasticha] nux stipitata, styli basi incassata persistente acuminata (B&H), the grain stalked, at the base of the style thickened, persistently acuminate.

2. one of the drupelets of a multiple fruit (as the raspberry)

3. the rounded prominence on the back of a sepal (as in the common dock) [Rumex];

- [Rumex] perianthii segmenta costa interdum extus basi in tuberculum granuliformem incrassata (B&H), the segments of the perianth with a costa thickened sometimes externally into a granuliform tubercle.

- [Rumex] perianthii segmenta interiora 2 v. omnia 3 basi extus saepe granulifera (B&H), the inner segments of the perianth two or all three at the base on the outside often granuliferous.

4. a small hard particle (e.g. of sand, sugar, salt);

- arenae grano simillima, most similar to a grain of sand.

- cum grano salis, with a grain of salt.

5. a minute portion or particle; see particle.

- pollinis granula sphaerica orificiis tribus protrusis aperta (F. Mueller), pollen grain sphaerical, open with three exserted orifices.

- pollinis granula lutea ovato-ellipsoidea utrinque obtusata, rima longitudinali hiantia (F. Mueller), pollen grain yellow, ovate-ellipsoid obtuse on both sides, gaping from a longitudinal fissure.

- cytioplasm chlorophyllosa cellulae a fronte cruciatim disposita, cujus crura e laminis duabus parietalibus divergentibus granum amylaceum unicum involventibus formantur (Wood, algae), the cytioplasm chlorophyllose, deposited [in the form of a cross] from the front of the cell [i.e. as seen from the front end of the cell - Wood], the crura of which are formed from the two diverging parietal laminae enclosing a single starch grain.

Grana (pl.n.II) tetrasticha (adj.A), abl. pl. granis tetrastichis: “the spores of certain Fungals” (Lindley).
