An Excursion Through my nerbarium

(recibido en la redaccih: 10.2.1977)
Durante una revisión de material de herbario encontré varias
formas críticas que se dan a conocer en el texto a continuación. Se
describe 8 nuevas formas o variedades y se propone 16 nuevas com-binaciones
nomenclatóricas. Se cita, además, 4 adiciones para la
flora canaria en general, y 8 taxones como adiciones insulares.
While revising herbarium material the author describes
8 new forms or varieties of vascular plants from the Canary
Islands. For 16 taxa or subtaxa new combinations are also
proposed. Furthermore, 4 species are cited for the first time

Centaurea: Cheirolophus. The genus Cheirolophus Cass. is
recognized as being segregated from Centaurea L. (viz. Flora
Europaea 4, l976), and most corresponding Canary plants ha-ve
been dealt with by J. Holub (1973, 1974). However, the
following taxa remain to be adapted:

Centaurea arbutifolia Sventenius, Bol.1nst.Nac.Invest.

Dr. J. Holub for his valuable indications concerning the
Cheirolophus species endemic in these islands.
Tolpis glabrescens Kammer
This species, only recently described from Tenerife (Ana-gaj,
seems to have a second locality in the Canary Islands:
cliffs of Guayedra below Tamadaba (Kunkel 17424: 27-VIII-
1974). Although 1 have not seen original material from Te-nerife,
Dr. Kammer's description fits our material very well;
however further comparative investigation is required.
BORAGINACEAE
Ec hium bonnetii Coincy
New to La Gomera: Kunkel 17974 (31-111-1975), La La-
ja, 400 m. The species was already known from Tenerife,
Gran Canaria, and (subspecies) Fuerteventura.

Lobularia intermedia Webb & Berth.
var. elongata Pitard
This seems to be a recognizabie variety, with narrow
leaves which are algo longer than usual; the infructescense
is very dense. In Gran Canaria this variety is known to occur
near to Ayacata, 1.300 m., and near to the Aserradero, 1.250
m.
MuiLhioia boiieana '%eM ex Christ
This endemic of the eastern Canary Islands was also
found (Kunkel 13187) in La Graciosa. Contrary to the opi-nion
of P. Sunding (1971) 1 believe this to be a "good spe-cies",
to be kept separate from the more freauent M. fruticu-losa.
- The aiithor thankr A . Hansen (C~pnhagen) fer
dealing with several specimens of this genus.
Matthiola fruticulosa (L.) Maire
This species ,which is frequent in parts of Lanzarote, in
its s.str. is an addition to our list of Canary plants. My mate-rial
frcm Pi'ertc Sxdinu 2nd Puerte las Nieves (U1312 C u ~ a -
ria) probably belongs to the same species. - Near to Tahi-che
(Lanzarote) we found specimens of large plants with a
woody base arid woody lower branches, forming cushions up
to 30 cm. in diameter. It remains to decide which subspecific
name may apply to our material, as M. bolleana (s.str.) is con-sidered
to be distinct and endemic in the eastern islands.
CAMPANULACEAE
Canarina canariensis (L.) Vatke, Linnaea 38: 700 (1874)
var. angustifolia Kunkel, var. nov.
A forma typica foliis angustioribus (1 - 1,5 cm. lat.) lan-ceolatis

CARYOPHYLLACEAE

Contrary to the opinion as expressed by Chaudhri (1968)
1 suggest that Helerochiton has a good reason to be kept as
a gerius, segregated from Herniaria where the species con-cerned
are treated on subspecific level.
The material from Fuerteventura (Jandía, i.e. Kunkel
12586), because of the more fragile pale branches, its sprea-ding
habit, and the longer internodes may be recognized as
ssp. bollei (F. Hermann) Kunkel, comb. et stat. nov.
Herniaria bollei F. Hermann, Fedd. Repert. 42: 221
(1937).
Heterochiton canariensis (Chaudhri) Kunkel, comb. nov.
Herniaria canaricnsis Chaudhri, Rev. Paronychiinae,
Utrecht, p.383 (1968).
The species is supposed to be endemic in Tenerife. 1 have
not seen material of Herniaria pujosii Sauv. & Vindt. H.fru-ticma

Its citation for Tenerife (Eriksson et al., 1974) seems erro-neous.
However it was recently discovered in Lanzarote whe-re
it grows in the Riscos de Guinate, at 350 m a.s.1.

grows also in La Gomera (Kunkel 11470), in walls of the
Barranco La Laja, at 600 m. approximstely.
Sclerocephalus arabicus Boiss.
N curious record, obviousiy new io the Lanary ísiands:
Fuerteventura, Jandía 150 cm, on rocky slope (Kunkel15098)
The plants are small, probably annual, 8 to 10 cm. tall; the
glaucous and linear leaves are up to 1 cm long, and the fruits
are globose-glomerate and spiny.-The species was (in my
herharii'im) mixed-i'ip with P t ~ r n tnh .?!..~f r, n m t h s~am P l n r a -

This more shrubby, darker leaved and almost glabrous
variety grows on dry slopes, together with specimens of the
iy pica1 val ieiy .
Helianthemum thymiphy llum Sventenius
After publishing a second locality (Roque Aceituno, near
to Femez: Kunkel 1976), a new locality of this obviously
long overlooked species may be added: Caldera Blanca, NW
oi limaniaya, where Andryaia gianciuiosa, iviicromeria vu-ria,
Asplenitim hemionitis and Adiantum capillus-veneris al-so
occur.
CONVOLVULACEAE

var. angustif olius (Pit. ) Kunkel, comb. nov.
Rhodorhiza florida Webb & Berth. var. angustifolia
Pitard, Fedd. Repert. 9: 379 (1311).
This variety was described by Pitard (1. c.) as Rhodor-hiza,
a fact obviously overlooked by Mendoza-Heuer (1971),
and the revalidation of the variety is herewith suggested.
Ipomoea hederacea (L.) Jacq.
This ornamental annual climber, much cultivated in
Gran Canaria, Lanzarote, etc., was found invading neighbou-ring
gardens in severa1 places. Our record (Kunkel 15859)
from Lanzarote (San Antonio gardens) might be listed as an
addition to the aliens of the Canary flora. The material was
named by A. Hansen (Copenhagen).

Vaisendero 75U m.
This might be (?) an adaptive form to an extremely
moist and more shaded environment. Almost a hundred spe-cimens
of this form were observed, over severa1 years.
Arbutus unedo L., the Mediterranean "Madroño"
In the vicinity of San Mateo (Gran Canaria), near a loca-lity
known as "El Montañón"), we found an admirable stand
of older trees of this species, freely flowering and fruiting.
However no natural regeneraiion has beeri noiiced.
LAURACEAE

PLANTAGINACEAE
Psyllium afrum (L.) Mirb.
This species, usuallg an annual, is quite common in the
Canary Islands, especially in the eastern group of the archipe-lago.
However, certain material from Lobos Island, Alegran-za
and La Graciosa has larger, elongated flower heads very
similar to Psyllium arenarium (Waldst. & Kit.) Mirb.
The three remainin species of this genus are endemic in
the Macaronesian islands and are listed as follows:
Psyllium arborescens (Poir.) Mirb., Hist. Pl., ed. 2: 333 (1830)
ssp. arborescens

var. mascaensis (Svent.) Kunkel, comb. nov.
Plantago arborescens Poir. var. mascaensis Svente-nius,
Addit. Flor. Canar. (Madrid), p.61 (1960).
both of which are endemic in Tenerife. In a wider sense the
Madeiran form should be cited as
ssp. maderensis (Decne.) Kunkel, comb. et stat. nov.

(Praha) 140: 131; 1972. A rare endemic of higher re-
gions of Gran Canaria, Tenerife, and La Palma.
SAPOTACEAE
Argania spinosa (L.) Skeels
In the Barranco de Agaete (Gran Canaria), at about 400
m. a.s.l., exists a sizeable specimen of this African plant, ob-viously
introduced but well established and which may
spread just as other introduced plants have.
SOLANACEAE
