270 CAJIPANULARU-M NOVARUM DECAK PRIMA.
and this explains why Visiani (1842) and Keiclienbach, jiin. (1860),
ascribe to C. Garganica their Illyrian specimens, which bear, more-
over, a great resemblance to the type.
The group is nearly related to (J. Elatines L., and C. elatinoides
Moretti, and also with C. Purtmselihujiana E. & S. C.femstreUata,
especially, has a striking similitude to the latter, as far as leaves
and stems are concerned.
In order to limit descriptions of the single species to differential
characters, I here give the common characters of the group.
Khizoma (4-8 cm. long., 4-6 mm. crass.), subeburneum ob
foliorum vetustorum bases persistentes dense noduloso-squamosum.
Caules diffusi, e saxorum rimis pendentes vel ascendentes, foliosi
raniosi. Folia cordato-orbicularia vel cordato-ovata, grosse crenatodentata
petiolata subsimilia ; radicalia petiolis limbo 3-6-plo longioribus
prtedita. Flores inter minores strict! racemosi. Eeceptaculum
rotundato-cyathiforme, nervis carinalibus conspicuis, suturalibus
brevibus. Calicis lobi lanceolati. Corolla caerulea tubo albicante,
in speciebus vestitis extus puberula, intus glabra aut imo pilosula,
ad I et ultra fissa, lobis patenti-reflexis. Staminum squamae dense
fimbriate ciliis obtusis ; filamenta squamis plus minus longiora angusta
; antherse lineares apiculo subulato. Gynoeceum 3-merum.
Stilus exsertus caerulescens, pars inferior glabra superiore incrassata
pilosa duplo fere longior. Stigmata linearia. Placentte crassae, ad
dimidium usque bilobae. Ovula pauca ovalia. Capsula globosa,
nervis prominentibus, parietibus pellucidis, rimil transversal! supra
basin duhiscens. Semina parva crassiuscuia, ambitu subovalia, basi
truncata, uno latere marginata.
C. GARGANICA Ten. (sensu stricto). Dense hirsuta vel incauopubescens,
raro glabella flaccida. Caules (20-45 cm. long. 1-1^ mm.
crassi) ab imo fere ramosi. Folia dentibus obsoletis aut conspicuis
latis obtusis prsedita ; radicaha subrotunda ; caulina cordata
plus minus acuta. Flores maiusculi, pedunculis tenuibus 8-5-plo
longioribus patulis suffulti, racemum longum laxum anguste
pyramidalem formantes. Alabastrum angustum cylindrico-conicum.
Eeceptaculum elhpsoideo-cyathiforme. Calicis lobi anguste lanceolati
acuti, corolla ^ breviores, sub anthesi et postea patulo-
reflexi. Corolla (10 mm. alta, 15 mm. lata) intus glabra ad %
fissa, lobis pulchre cyaneis arcuato-patulis. Staminum squamae
cordato-acuminatae, filamentis aquilongae ciliavum longitudine
8-plo latiores ; antherae filamentorum squamarumque summam
longitudine ajquantes. Pollen sulfureum. Stilus corolla duplo
longior ; stigmata stilo 8-plo breviora. Capsula parva : (3 4
mm.). Semina (0-5 : 0-45 mm.) planiuscula luridaopaca rugosula.
