Brot. lusit.I.p.287.2)Bornmuller in Beih.Bot.Centr. 61B:72(1941) mentioned that a Sintenis gathering (Sint. 1890:3522) from Egin (B7 Erzincan:Kemaliye) represented an undescribed species of Michauxia. The incomplete specimen (without capsules and only two flowers) was given the exsiccata nomen, Michauxia spathulaefolia, by Haussknecht. The material I have studied from the Sintenis collection in Lund agrees with the description given by Bornmuller. The two flowers have a 5-fid calyx and corolla; calyx appendages are absent and the corolla is 1/3 or 1/4 divided; the style is trifid. The plants therefore belong not to Michauxia but to Campanula and possibly represent a new species related to Campanula peregrina L., but the material is insufficient for description.3)
Names
Fr.: Campanula voyageuse4)
P.: Campanula pregrinaHabitus
Character. Hispidissima, caule simplici, foliis dentato-crenatis in petiolum alatum angustatis sessilibusque, floribus axillaribus. Diagnosis. Caulis erectus, simplicissimus. Perennis.5)
Herbae biennes.6) Erect, rather bristly-stemmed biennial, 2-3 ft. Flower stems simple. Obs.3. Nimis affinis Campanula peregrine Lin. (Mant.p.20 4.) et Campanula lanuginosae La Marck (Dic.Encycl.Tom. I.p.584.) Sed ultra alias notas in descriptione datas, ab illis differt radice perenni, nec bienni; caule asperius hispido, anguloso, nec tereti; foliis oblanciolatis inaequaliter crenatis, seu duplicato-crenatis, subtus inter venas hispidas glabris; petioli marginibus non serratis seu dentatis; floribus lateralibus saepius non solitariis; corolla valde maiori, fundo albido, nec atrocaeruleo.7) (Not available yet!)Leaves
Folia inferiora petiolata, lamina in petiolum decurrente; superiora sessilia; omnia acuta, dentato-crenata, crenis denticulatis, rugosa.8)
Folia basalia et caulina inferiora in petiolum ad 10cm. longum attenuata.9) Rosette leaves ovate to spatulate, to 4 in. long, crenate, rugose, stem leaves sessile, ovate, acute.Flowers
Pedicelli solitarii, binive. Calyx laciniis lanceolatis corolla paullo brevioribus. Corolla coerulea. Floraison. Ete.10)
Stylus filiformis, trifidus.11) Flowers in spikes, calyx ciliate, without appendages, lobes broad, corolla deep violet toward the center with lighter lobes, funnelform.Chromosomes
The peculiar, often cultivated, Campanula primulifolia Brot. from S Portugal seems to be related to Campanula peregrina (both species have the same chromosome number of 2n = 26) and should therefore be placed in the same section.12)
Segundo os dados de Tischler (1950), Darlington & Wylie (1955), Love & Love (1948; 1961), Alava & al. (1958, 1959, 1960) e Bocher (1960), os numeros basicos no genero Campanula sao 8, 10, 12, 13, 14 e 17. Em face das observacoes de Larsen (1954) e das nossas em Campanula lusitanica, fica estabelicida, fora de duvida, a existencia de mais outro numero basico, que e 9. Atendendo a que Campanula colorata possui n = 12 e Campanula erinus n = 14, consideramos provavel que 6 e 7 sejam, respectivamente, os numeros basicos dessas especies(A existencia de n = 6 nos generos Fasione, Asyneuma e Phyteuma, bem como de n = 7 em Specularia, esta de acordo com este ponte de viasta.), e que elas correspondam a tetraploides. O numero 13, encontrado em Campanula cervicaria e Campanula peregrina (primulaefolia), teria sido derivado de 12 ou de 14, mais provavelmente de 12. Sendo assim, a serie de numeros basicos em Campanula sera 6, 7, 8, 9, 10 e 17.
A explicacao do aparecimento das series aditivas de numeros basicos deste tipo e um problema complexo, porqunto e muito dificil estabelecer se a evolucao se deu no sentido do aumento ou da diminuicao do numero de cromosomas ou simultaneamente nas duas direccoes. Em Campanula persicifolia, Darlington & La Cour (1950) mostraram que ambos os processos podem ter lugar.13)
Fruit
Capsula trilocularis, poris ca. medianis dehiscens.14)
Seed available, in small quantity. Species actually grown or used for breeding 15) Nous n’avons pas vu chez le Campanula Medium d’ovaires a quatre loges, mais une anomalie de ce genre a ete mentionnee par Alph. De Candolla (op. cit., p. 381, tab. II.B, fig. 9) pour le Campanula Medium et (op. cit. p.29) pour le Campanula peregrina 16).Living
Lieu natal. Dans les sites ombrages et humides sur les rochers audessus de Punhete au bord de la riviere du Zezere; aux environs de Monchique; dans les contrees sous-alpines de la province de Beira, selon Brotero.17)
Origin
Mediterranean region. According to Dr.J. Holmboe book in Cyprus are found growing at shady places, common especially in the valleys of Troodos mountains 18).
Observations. * 1. Linne dit de cette jolie Campanule, quelle a leve entre des graines du Cap de bonne Esperance. Mais il est peu probable qu'une plante que l'on rencontre dans les contrees montueuses et sous-alpines du Portugal, se retrouve au Cap, et nous supposons que c'est par quelqu'accident que Linne se sera trompe sur l'origine de cette Espece. * 2. Planta in hortis nomine Campanula peregrinae culta, minor plerumque nostra, omnibus partibus contracta, praesertim calyce, corolla, foliisque; nec tamen vere differre videtur.19)
