Var. r/. corallina. {T. corallina, Ait. — T. europaa. Hook. /. c. — T. ru-

 tinis*. — Ramuli annotini nunc per totum annum, nunc hyeme tan- 

 tum sanguinei, etiam in prsecocitatis varietatibus baud raro occur- 

 runt. 

 Varietates a. et 77. species forsan duas sistunt distinctas, permultis 

 hybridis hortensibus intricatse. 



Arbor 60-100-pedalis, diametro 2-3-pedali. Cortex vetustus gri- 

 seo-fuscus, rimosus. Rami cinerei, verrucosi, arrecti. Coma ovalis 

 vel subpyramidalis. Ramuli annotini olivacei, vel lutei, vel virides, 

 vel sanguinei, v. violacei, punctati. Ramuli juniores pilis patentibus 

 hirti. Gemmae ovatse, obtusse, fuscescentes. Foliorum lamina i-4 

 poUices longa (surculorum sterilium folia nonnunquam semipedalia), 

 nunc totidem lata, nunc longitudine angustior, supra subrugosa, Iset^ 

 vel obscure viridis, subtus pallid^ virens saepeque lucida, basi 5- v. 7- 

 nervis, serraturse vel crenulse plus minusve approximatse, mucrone 

 brevi albido subcartilagineo apice sphacelato acuminatse ; petiolus 

 ^-3 poUices longus, hirsutus v. velutinus, simul ac axillae, costa, nervi 

 venaeque paginse inferioris pilis moUibus patulis hirti v. hirsuti. Brac- 

 teae foliorum longitudine, vel paulo breviores aut longiores, 3-8 li- 

 neas latae, liguliformes, v. lanceolatae, v. lanceolato-oblongae, obtusse 

 vel acutse. Pedicelli divaricati plus minusve arrecti, nunc pedunculi 

 parte libera longiores, nunc breviores, plerumque bractea paulo supe- 

 rati, umbellati v. corymbosi, v. subtrichotome cymosi. Sepala ovato- 

 lanceolata, obtusiuscula, dorso glabrescentia, facie marginibusque 

 sericea, 2J-3 lineas longa, pallide lutea. Petala 3-4 lineas longa, 



* Nuces juniores quasi ecostatse videntur (talesque tribuuntur ab illustr. 

 DeCandolle Tillce&uad rubrce), tunc costae, demum prominentissimae, tomento 

 denso velantur.
