A Grammatical Dictionary of Botanical Latin

 
-ys: nouns ending in -ys (sg. generally f. III)

1. The Greek word for mouse and also rat is mys, gen. sg. myos (s.m.III), a noun of the third Greek declension (related to Latin 'mouse:' mus, gen. sg. muris, q.v.) is sometimes rendered into Latin words ending in -mys.

The following is a paradigm made by adding the Latin Third Declension endings to the stem my-:

mys, gen.sg. myis (s.m.III), q.v., mouse, q.v. and rat.



singular plural singular plural Nom. mys myes Calomys Gen. myis [myum] [myium] Calomyis Dat. myi myibus Calomyi Acc. myem myes Calomyem Abl. mye myibus Calomye


myidion,-i (s.n.II), abl. sg. myidio, the diminutive of mys: little mouse (my-idion).

Calomys americanus, the deer-mouse; Oryzomys palustris, the rice-rat; Peromyscus californicus, a deer-mouse; Megamys patagonensis, a fossil rodent; Antechinomys laniger, the little jerboa.

NOTE: Steyskal (1969) used this noun to display "examples of irregularity in genitive endings [which] pertain to parasites whose specific names are formed from names of host-genera ending in the word 'mys.'"

The host genera were Apomys; Cynomys; Dipodomys; Dremomys; Heteromys; Hesperomys; Otomys; Phascolomys; Pitymys; Rhabdomys; Scotinomys; Thallomys; Thomomys; Zelotomys.



epithets: gen.sg. ending in -myis



gen.sg. endings (correct) gen.sg. endings (other) phascolomyis -mydis: dremomydis hesperomydis, otomydis, < thallomyis pitymydis [declined like -chlamys] -mysi cynomysi, thomomysi (mys + i) -myia otomyia (my + ia) -mius dipodomius (m + ius) -muris thomomuris (the gen.sg. of the Latin)


The Greek spelling is gen. myos; acc. myn; nom.pl. myes, acc. pl. myas, dat. pl. mysi and mysi(n), etc. indicating this noun is not of the sort with the genitive in -mydis. The majority of epithets were (incorrectly) composed in -mydis, however, and other variants.

2. Greek nouns ending in -us (upsilon), gen.sg. -udos, rendered into Latin as -ys, -ydis (s.f.III), abl.sg. -yde;

-chlamys,-ydis (s.f.III), mantle [> Gk. chlamys,-ydos, s.f.III a short cloak or mantle (Lat. paludamentum); see '-chlamys,-ydis: in Gk. comp.';



singular plural Nom. Coleochlamys Gen. Coleochlamydis Dat. Coleochlamydi Acc. Coleochlamydem Abl. Coleochlamyde


Aulacochlamys (alga); Basichlamys (alga); Coleochlamys (alga);

Ecdysichlamys (alga); Gloeochlamys (alga); Keriochlamys (alga);

Leptochlamys (alga); Lobochlamys (Chlorophyceae, Protist);

Nephrochlamys (alga); Oogamochlamys (Chlorophyceae, Protist);

Phaeoschizochlamys (alga); Pyramichlamys (alga); Schizochlamys (alga); Sklerochlamys (alga); Tetrachlamys (alga); Vitreochlamys (alga).

NOTE: -stachys,-ydis (s.f.III), spike, is an exception in that in Greek

the genitive is '-yos' (see next entry).

3. Greek nouns ending in -us (upsilon), gen. sg. -uos, rendered into Latin as -ys,-yis;

-pitys,-yis (s.f.III), pine-tree [> Gk. pitys,-yos, s.f.III, a pine-tree (Lat. pinus)].



singular plural Nom. Hypopitys (s.f.III) Gen. Hypopityis Dat. Hypopityi Acc. Hypopitym Abl. Hypopitye

-botrys,-yis (s.m.III), cluster or bunch of grapes (Lat. racemus).

-drys,-yis (s.f.III), oak; Halidrys (genus of marine plants, alga); Phycodrys (alga); Pseudophycodrys (alga).

-pitys,-yis (s.f.III), pine.

EXCEPTION: botanical usage for Stachys L. (s.f.III) Horse-nettle, which would be Stachyis in the gen. sg., is rather Stachydis [> Gk. stachys,-yos (s.m.III), spike, an ear of corn [Lat. spica; note the Gk. noun is considered feminine in botanical usage];



singular plural singular plural Nom. -stachys -stachydes Nom. Stachys Gen. -stachydis -stachydum Gen. Stachydis Dat. -stachydi -stachydibus Dat. Stachydi Acc. -stachydem -stachydes Acc. Stachydem Abl. -stachyde -stachydibus Abl. Stachyde


Subfamily: Stachydoideae (Stachys,-ydis).

NOTE: Gk. compounds using stachys as a prefix or suffix may use stachy-, stachyo-; -stachys,-ydis; -stachyus,-a,-um; see stachy-.

4. Greek nouns rendered in Latin Third Delcension as -yx, gen. sg. -ychis: bostryx,-ychis (s.m.III) [Gk. bostryx, gen. sg. bostrychos (s.m.II), (note Gk. xi of nominative becomes chi in the other cases)];



singular plural singular plural Nom. bostryx bostryches Nom. Bostryx Gen. bostrychis bostrychum Gen. Bostrychis Dat. bostrychi bostrychibus Dat. Bostrychi Acc. bostrychem bostryches Acc. Bostrychem Abl. bostryche bostrychibus Abl. Bostryche

Acc. calycem calyces Abl. calyce calycibus
