116*. Lepidium peregrinum Thellung ap. G. Cl. Druce in The Bot. 
Exchange Club Brit. Isl.; Report for 1912, vol. III, part III (Jun. 1913), 
p. 158 cum ic., p. 147 (sect. Dileptium, subsect. Eudileptium, grex Pseudo- 
Ruderalia Thell.). — Perenne? Caulis suberectus, elatus, fere eylindricus 
(leviter anguloso-striatus), glaberrimus subnitidus, foliosus (foliis inferiori- 
bus saepe fasciculatis), ramosus. Folia caulina lanceolata, utrinque 
attenuato-acuta, acute serrata serraturis adpressis, margine (praesertim 
basi) pilis gracilibus cylindricis acutis minute ciliata, ceterum glabra. 
Racemi sparsi, in ramis laterales, folio oppositi, satis multiflori. Flores 
minuti; sepala anguste ovato-elliptica albo-marginata, dorso pilis longius- 
culis villosula, satis diu persistentia; petala rudimentaria setacea, calyce 
breviora; stamina 2 (—4) mediana; glandulae 4 (—6) triangulari-lanceo- 
latae, calycis ca. Le longitudine aequantes. Racemi fructiferi satis 
breves, axi glaberrimo vel apicem versus minute et remotissime puberulo, 
leviter anguloso-striato, pedicellis gracillimis subcapillaribus, latere in- 
teriore pilis brevissimis (diametro pedicellorum brevioribus) puberulis, 
leviter extrorsum arcuatis, fere horizontalibus vel subdeclinatis, silicula 
1!/—2-plo longioribus. Silicula ovata, modice compressa, basi ob- 
tusiuscula, apice circumferentia anguloso-acuta, distincte et satis acute 
emarginata marginibus emarginaturae angulum fere rectum formantibus, 
dentibus alaribus in utroque latere triangulari-acutis porrectis; stylus 
brevissimus, stigma in fundo emarginaturae subsessile; valvulae cari- 
natae, apicem versus anguste alatae; septum oblanceolatum (1 : 4—5), 
stylo brevissimo cum stigmate apiculatum. Semina minutissima, an- 
guste ovoidea (1:2), compressa, fulvo-fusca, fere laevia (leviter scrobi- 
culata), immarginata; embryo notorrhizus. — Rami (tantum suppetentes) 
ca. 40 cm longi. Folia 3—4 cm X 3—7 mm. Sepala !/—?/; mm longa. 
Silicula 2X Ui mm. Semen 1 X !/, mm. — Patria ignota; planta pere- 
grina, verisimillime ex Australia oriunda, in Angliam introducta, — 
England: Galafoot (Galashiels, Scotia), 1910, leg. Ida M. Hayward. 
— Species affinis nonnullis speciebus australiensibus ex grege Pseudo- 
Ruderalium, praesertim L. hyssopifolio Desv. em. DC., quod tamen differt 
racemis terminalibus nec lateralibus, pedicellis glaberrimis, floribus et 
fructibus majoribus, silicula distincte rhombica multo majore, quam pedi- 
cellus haud conspicue breviore; L. pseudo-ruderale Thell. dignoscitur caule 
et foliis pubescentibus, racemis terminalibus, foliis + oblongo-obovatis 
obtusiusculis, pedicellis brevioribus silicula elliptica obtusiuscula levius 
emarginata; L. Merralli F, v. Mueller (mihi ex descr. tantum notum) 
differre videtus statura pumila (7—12 cm), foliis linearibus integris vel 
in lobos paucos angustos productis, silicula rhomboideo-orbiculari levis- 
sime emarginata obtusiore. ZL. divaricatum Soland. (spec. africana), quo- 
dammodo simile (praesertim subsp. linoides [Thunb.] Thell), distinguitur 
pedicellis brevibus (siliculae subaequilongis) e basi suberecta extrorsum 
curvatis et silicula angustiore obtusa levius emarginata.
