Nomenclatuur

Reut. (1865)1)

W. D.J. Koch ex F.W. Schultz.2)

Section VI: Elatines Wohlf. (1895)3)

Often confused with Campanula Waldsteiniana 4).

Synonym: Campanula Waldsteiniana R. et S. v. Freyeri Rchb. f. (1860) 5)

C. x wockei = C. waldsteiniana x C. tommasiniana.6)

Habitus

Very distict indeed; very small linear foliage, very shiny; stems clothed with tubular lilac bells. A very small grower, but easy to manage in ordinary soil. Often erroneously sent out as Tenorii and as Waldsteiniana.7)

Glabrous perennial, stems mostly several, spreading to erect, slender to 6 in. high or more.

Rerenni. Pianta glabra o quasi cespugliosa, a fusti eretti, flessuosi, semplici o con qualche rametto (15-25cm.). 8)
Campanula Wannarii. Steli alti circa cm. 30. Nonche moltissima altre entita quali Campanula muralis Vill., delle Alpi orientali, Campanula excisa, Schleich., delle Alpi centrali, Campanula thyrsoides L., delle Alpi centrali ed orientali, Campanula Zoysii Wulf., delle rupi calcaree delle Alpi orientali, Campanula Tommasiniana Port., delle Alpi estremo-orientali ed Istria, Campanula Morettiana, Rchb., delle Alpi centrali, Campanula rhomboidalis L., ecc., tutte a fioritura estiva (giugno-settembre). 9)

Leaves

Leaves short-petioled, linear-lanceolate to lanceolate, to 2 in. long, minutely serrate.
Fg. cauline lineari-lanceolate. Formanti un racemo terminale.10)

Flowers

Flower measuring,between 15 - 25mm (5/8 to 1 inch.)11)
Flowers axillary, nodding, mostly exceeding the leaves, calyx without appendages, lobes linear, corolla pale violet, to ¾ in. long, tubular-campanulate.
Ag. - Fi. formanti un racemo terminale. Calice un po'vischioso, a lobi brevi, lineari, spesso denticolati. Corolla azzurra, tubuloso-campanulata, a lobi brevi ed acuti. Filamenti un po'ristretti alla base.12)

Chromosomes

Zytotaxonomisch wurden unsere endemischen Campanula-Azten untersucht deren Fundort Felsenspalten sind (Campanula tommasiana, Campanula istriaca, Campanula fenestrellata, Campanula waldsteiniana, Campanula portenschlagiana). Fur alle zitierte Arten wurde die Zahl der Chromosomen 2n = 34 festgesetzt 13)

Slika 2. - Campanula tommasiniana. Mitoza (Feulgen). a) 2n = 34. b) 2n = 17. Crtez. - Zeljka Lovasen-Eberhardt 1971

Unutar populacije vrste Campanula tommasiniana nadene su dvije biljke (od 14 sabranih) kod kojih je utvrden broj kromosoma 2n = 17 (slika 2). Zakljucak: Citotaksonomski su istrazene neke endemicne vrste roda Campanula, te su nadene vrlo zanimljive varijacije broja kromosoma kod nekih vrsta. 1) Za vrstu Campanula tommasiniana, osim 2n = 34, nadeno je i 2n = 17 kromosoma.
Prema dobivenim rezultatima cini se da je za vrste Campanula tommasiniana i Campanula portenschlagiana osnovni broj kromosoma 2n = 16 + 1, dok su ostali kromosomski brojevi (34, 51) rezultat porasta ploidije14)

Breeding

* Campanula hybride cv. 'Molly Pinsent' - Locality: England - Timsbury alpine house - Photographer: Graham Nicholls - Note: This is a very old cultivar that was almost lost to cultivation. I was given a small piece and have manage to distribute it to various growers. It's a vigorous and free flowering cultivar however its origin is not known, although it looks to have some Campanula tommasiniana in it.

Origin

Yugoslavia.
Luoghi rupestri: Istria sul M. Maggiore (Mala-Ucka, Vela-Ucka, Sovrana), nella parte super. della Draga di Moschienizze e sul M. Plaunik; 4-5. (Endem.).16)

Use

Velkou vyhodou zvonkú je, ze se nesnadno krizí a nemusíme mít ani u velkych sbírek obavy ze samovolné nezádoucí hybridisace, jako je tomu u mnoha junych rodú. Múzeme proto bez obav sbírat semena ze zahradních rostlin pro vlastní potrebu i pro vymény semen. Je vsak nutno dbát na správnou determinaci, protoze se prílis casto ve sbírkách vyskytují rostliny spatné urcené. Neznamená to, ze by byla hybridisace vyloucena. Velmi vzácné k ní dochází v prírodé, rovnéz umélym sprasováním vzniklo nékolik krízencú, které nasly své místo na skalkách a ve sbírkách péstitelú, které nasly své místo na skalkách a ve sbírkách péstitelú. Jsou t napr. C. x pseudoraineri = C. carpatica x C. raineri, C. x pulloides = C. carpatica var. turbinata x C. pulla habituelné pripomínající C. pulla, kdezto C. x wilsonii syn. 'G.F. Wilson' je hybrid stejnych rodicú, ale habituelné pripomíná více C. carpatica var. turbinata, C. x warleyensis = C. carpatica x C. cochlearifoli a casto se péstuje v plnokvété form. C. x kewensis = C. excis x C. arvatica, C. x wockei = C. waldsteiniana x C. tommasiniana. Starsí literatura uvádí jesté celou radu krízencú, my jsme je vsak nikdy nepéstovali, ani jsme se s nimi nikde ve sbírkách nesetkali.17)
