Otostegia repanda, ex parte (nempe quoad plantam arabicam, exclusa specie abyssinica), Benth., in D. C., Prodr. , vol. 12
p. 5aa.
Fruticosa, inermis. Bamis uovellis dncano-lanulosis. Foliis ovatis v. rhombeo-ovatis (inferioribus
plerumque subcordatis), aeutis, serrato-v. crenato-dentatis, subrugosis, longe petiolatis, supra viri-
dibus villosulis, subtus (saltern junioribus) ineano-tomentellis. Cymis breve pedunculatis, contractis,
5-11-Boris. Bracteis herbaceis, subulato-filiformibus, ciliolatis, calyois tubum æquantibus. Calycis la-
bio superiore ovato v. ovato-lanceolato, acuminulato, integerrimo, brevi ; labio inferiore varie den-
tato y. angulato, plerumque obovato v. subfotundo, corollam subæquante.
Frutex erect us, ramosus, partibus herbaceis pilis brevibus articulafis simplicibus basi incrassatis indutus glandulisque
minimis (oculo nlido vix conspicuis) sessilibus v. stipitiUatis punctulatus. R ami vetuli speciminibus lectis desiderantur. Rami
novelet 1-2 1/2-pedales, stricti', virgati, striatuli, obtuse tetragoni., foii.ati, flprigeni, subincani, paniculati; ramulis -plus
minusve divergentibus, simplicibus, gracilibus, elongatis (plerumque internodio demum Iongioribus), foliatis, decussatim
oppositis, sæpissime florigenis. Internodia foliis plerumque longiora (interdum subtriplo). F olia herbacea, crassiuscula, mollia,
opaca, penninervia (nervis supra impressis, subtus costaque prominentibus), reticula to- venulosa, basi truncata v. cuneata
v. interdum inferiora subcordata, in utraque pagina glandulis copiosissimis conspersa, supra laxius densiusve villosula, subtus

sæpius subdimidiô brevior. Folia ramealia inferiora circiter bipollicaria (petiolo haud computato) ; superiora (pleraque floralia)
gradatim minora. Folia ramularia conformia foliis ramealibus at minora (ad summum etiam inferiora vix pollicaria). F lores
cymosi, spectabiles, brevissime pedicellati, bi-v. tri-bracteati (centrales ebracteati), in quavis cyma subfastigiati. Cymæ axil-
lares, breve pedünculatæ, bifidæ v. iteratim dichotomæ, foliis floralibus superatæ, plerumque 7-9-floræ, supra ramorum
novellorum eorumque ramulorum mediuminflorescentiam interrupte spicatam quasi verticillatam efformantes. Pedicelli cras-
siusculi, cum calyce continui, simulac cymæ rhachis et pedunculus incano-tomentelli, basi articulati. Bracteæ rigidulæ, erectæ
divergentes, muticæ, uninerviæ, tomentellæ. Cal yx 6-7 lineas longus, corolla paulo brevior (computato limbo). Tubus limbo
brevior, obconicus, plicato-decemcostatus, herbaceus, extus undique incano-villosulus (et sub indumento glandulis plus
minusve crebris conspersus), intusa medio ad faucem barbato-villosulus (præsertim costis), cætero glaber. Limbus bipartitus,
subringens, scarioso-membranaceus, semi-pellucidus (in sicco pallide fuscus v. fusco-stramineus), reticulatus, remote cilio-
latus, nervis et venis villosulus simulque glanduloso-punctulatus, cætero glabellus (sub lente glandulis punctiformibus conspersus).
Segmentum superius subpatens v. patenti-erectum, segmento inferiori multo minus, tubosubduplobrevius, trinervium

tubo duplo longius, patens v. subdeclinatum, septemnervium totidemque lobulatum v. dentatum, lobulis v. dentibus nunc
subæqualjbus nunc inæqualibus, muticis v. nervo excurrente mucronulatis. Corolla alba (ex adnotatione cel. Bottæ), 8-9
lineas longa, ringens, glandulis minimis puncticulata. Tubus faucem calycinam subæquans, n-nervius, obconicus, extus
glaber, intus supra medium annulo carnosd obliquo interrupto (inter stamina superiora) setulis obtusis exarticulatis barbato-
hirtello auctus, fauce egibbosus. Labia exserta, subæquilonga (v. labium inferius paululo longius labio superiore), dissimilia.
