144 MARCORAUCEAE-MELAST~MATACEAE SMITHSONUN CONTRIBUTIONS TO BOTANY
4377,4397,4402,4545).
Determinations are tentative pending revision of the genus.
Our specimens agree reasonably well with specimens (US)
from Martinique (Stehle 4861, 6148, 6813, 6836) but others
determined as this species have conspicuously reticulate
venation and lack the revolute margins.
Marcgravia trinitatis
Marcgravia trinitarir Presl, 1845:122.-Urban, 1896516.
Marcgravia recrijlora Trim & Planchon, 1862:364.
Marcgravia rectiflora var. jacquinii Triana & Planchon, 1862:366.-Urban,
1896515.-Howard, 1970.
Leaves leathery, with inconspicuous venation, marginal
glands as a line of inconspicuous glands 2-3 mm from margins
and 1-2 conspicuous domatia (pocket glands) -2-3 mm from
midrib -1 cm above leaf base; petioles 1-2 mm long,
essentially sessile; flowers erect on 4-5 cm pedicels; stamens
-60.
[Martinique?] and St. Lucia; apparently rare in interior
rainforest of Dominica: Laudat (Ramage s.n.), Sylvania (Hodge
475,1143, Syndicate (Nicolson 4083).
The type, Sieber 342, supposedly collected in Trinidad by
Franz Wrbna, probably involves an error, because the species
does not occur on Trinidad. It may have been collected on
Martinique by Franz Kohaut, perhaps at La Trinitt5. The same
situation exists for Rauvoljia biauriculata (Apocynaceae).
Marcgravia umbellata
Marcgravia wnbellata Linnaeus, 1753:503.-Urban, 1896517.
Leaves not leathery, with conspicuous venation; glands on
leaf margin (line of dark dots on pale margin), the lower third
of midrib with 1-2 domatia on each side below; petioles 7-9
mm; flowers at -90’ angle on -3 cm pedicels; stamens -15.
Lesser Antilles to Guyana and Colombia; common in
treetops of Dominican rainforests 100-800 m: Carib Reserve
(Stehlet 6099), Delices (Whitefoord 3705), Deux Branches
(Hodge 1977,3469), Fon Pays (Hodge 2863), Freshwater Lake
(Hodge 1775, Nicolson 1838, Whitefoord 5141), La Chaudiere
(Hodge 3513), Laudat (Hodge 1968), Lisdara (Hodge 477,
2386), Morne Colla Anglais (Hodge 1048), Mome Micotrin
(Chambers 2571, Stern & Wasshausen 2563, Wasshausen &
Ayensu 339, Webster 13238, Wilbur 7393, Morne Plat Pays
(Hodge 1729), Mosquito Mountain (Webster 1356@, Petite
Soufriere Bay (Stern & Wasshausen 2485), Pointe Lo10
(Chambers 2518), Pont Casse (Fosberg 48300, Wasshausen &
Ayensu 368), Sylvania (Hodge 1048), Syndicate (Hodge 2708,
Whitefoord 5631).
Ruyschia Jacquin
Ruyschia clusiifolia
Ruychia clusiifolia Jacquin, 1760: 17. “clusiaefolia”.-Urban, 1896520.
Climbing shrub; leaves obovate, retuse; floral nectaries
attached near pedicel apex.
Guadeloupe to Martinique; occasional high-climbing epiphyte
in Dominican rainforests, 300-610 m: Boiling Lake
(Eggers 1098), La Soie at 2000’ 1670 m] (Eggers s.n.), Laudat
(Eggers 787), Syndicate (Hodge 2901, Nicolson 2901).
Schwartzia Vellozo
There is a possibility that Schwartzia is so similar to earlier
Swartzia that it is confusable and to be treated as a later
homonym under Art, 64.3 (ZCBN). Both genera were named for
Olof Swartz (also Swartsia).
Schwartzia spicwora
Schwartzia spuifora (Jussieu) Beddell in Howard, 1989,5:309.
Marcgravia spicijlora Jussieu, 1809:402.
Norantea spicifora (Jussiw) Kmg & Urban in Urban, 1896520.
Climbing shrub; leaves obovate, obtuse, coriaceous; floral
nectaries mostly attached below mid-pedicel.
Guadeloupe, St. Vincent, Venezuela; in Dominican rainforests
700-1400 m: Couliaboune [Mome Anglais] (Wilbur
7962), Dleau Gommier (DeFilipps I79), Laudat (Chambers
2683), Morne Diablotins (Chambers 2648, Nicolson I985),
Pont Casse (Ernst 1129), Valley of Desolation (Whitefoord
5495).
MARTYNIACEAE

Central America and West Indies, pantropically cultivated
and escaping; on dry west coast of Dominica in open areas near
sea level, probably not native: between Colihaut and Coulibistri

Garden (Hodge 1002).
MELA~OMATACEAE
(by A.C. Nicolson)
Ed. Note: Members of this family are usually calledcre-cre
on Dominica. Many are weedy and common, others are rare.
Generic limits are sometimes difficult to define, although the
species are relatively well defined. I thank Dr. John Wurdack
for reviewing this treatment,
