Flora of Dominica, Part 2 - Smithsonian Institution Libraries

40 ASTERACEAE SMITHSONIAN CONTRIBUTIONS TO BOTANY
Providence Valley (Hodge 2 0 , Roche d’Or Estate (Stern &
Wusshuuren 2579), Springfield (King 6332), Sylvania (Hodge
777, 778,779). Syndicate (Chambers 2654, Whitefoord 3581).
Our material falls in forma vuleriunifolia.
As discussed by Belcher (195628), the basionym (Senecio
vuleriunifoliur) was attributed to Wolf in an 1825 Berlin
seedlist by Reichenbach (Halle) and Lessing (Berlin). Because
no one has seen this publication, neither the validity (with
description or nomen nudum?) nor the authorship of the name
can be established. Sprengel’s publication, accepted here as the
first known publication with a validating description, appeared
between January and March of 1826, attributing the name to
Link. At that time Link was in charge of the Berlin Herbarium.
I find no trace of a Wolf, Wolff, Wulf, or Wulff associated with
the Berlin Garden at that or any other time.
Erigeron Linnaeus
Erigeron kminskianus A.P. Candolle, a sprawling plant
with elongate stems, was cited for Dominica (with exclamation

Erigeron polycladus
Erigeron polycladm Urban, 1903,3:403.Stehle,1954b73.
Leaves to 10 mm x 3 mm, narrowly spatulate, entire but with

be capable of rooting, then upturned with a single head.
Involucral bracts in 2-3 series, deflexing from naked receptacle.
One achene found, with bristly pappus in a single series.
Lesser Antilles; a new record for Dominica on north coast
“Small colony on bluffs above sea”: L’Anse Noire near Pointe
Baptiste, alt. -50 ft [ 15 m] (Ernst 2079).
Our material is referred here with doubt because of its
incompleteness, “Cespitose and succulent composite about 2
inches tall.”

Koanophyllon Arruda da Camara
The etymology of this generic name is obscure. It may be a
lapsus for Kyunophyllon, indicating the leaves (phyllon) as a
source of a blue dye (cyanin or mil), as discussed by the author.
Koanophyllon celddvolium
Kmnophyllon celtidifolium (Lamarck) King & Robinson, 1971b:149, “celtidifolia”.--i(ing
