ENGLISH SUMMARY<br />

The g<strong>en</strong>us Lumia in Spain<br />

This is a revisión of Spanish material of Luzula collected by the author and,<br />

in addition, of the Spanish specim<strong>en</strong>s oí this g<strong>en</strong>us in the herbaria of Madrid (M)<br />

and Barc<strong>el</strong>ona (BC and BCF). Iavestígation of intraspecific variation has led to<br />

the description of some sew taxa after the examination of abundant material subjected<br />

to biometric studies.<br />

The great variability of L. forsteri, L. silvatica, L. nutans, L. caespitosa, L. campestris,<br />

L. sudetica and L. multiflora is interesting. In the Pyr<strong>en</strong>ees L. lutea differs<br />

from the typical plant of the Alps, and the author proposes its recognition as ssp.<br />

pyr<strong>en</strong>aica.<br />

Chorology and new taxonomic characters (see the figures) are based on rec<strong>en</strong>tly<br />

collected material. L. pallesc<strong>en</strong>s and L. luzulina are new for the flora of Spain.<br />

A demonstration is giv<strong>en</strong> of the possibilities of palynological studies in investigating<br />

the geographical variaríon within species. The author has also cornpiled<br />

a list of bibliographical refer<strong>en</strong>ces to cytological data, which should be of<br />

use to workers on caryosystematics who need to study caryotypes of individuáis<br />

from natural populations. With this in view, he has paid special att<strong>en</strong>tion to the<br />

microtaxonomy of this g<strong>en</strong>us.<br />

The paper is based on classical taxonomy, with a bias in the direction of the<br />

new systematics and the study of variation within and betwe<strong>en</strong> populations. The<br />

author hopes that it will be useful for taxonomists and cytologists, and also<br />

for plant collectors in Spain.<br />

NOTAS FINALES. — Terminado este trabajo, antes de su aparición definitiva,<br />

he recibido la interesante publicación de S. RIVAS-MARTÍNEZ, 1963, «Estudio<br />

de la vegetación y flora de bis sierras de Guadarrama y Gredos». An. I. Bot.<br />

A. J. Cavan. 21 (1) : 1-32S. Madrid. En las páginas 287-289 cita varias Luzula<br />

y describe algunas novedades, con refer<strong>en</strong>cia al pres<strong>en</strong>te trabajo, que pudo consultar<br />

cuando permanecía inédito.<br />

L. spicata (L.) DC. no parece corresponder a la ssp. mutabilis de los Cárpatos;<br />

no es probable que sea ssp. spióata, pero es prematuro asignarle «status»<br />

definitivo.
