holotypus: Malagasy Republika, near Jar- 
din Botanique, Gravirage, 6 km SW of Joffre- 
ville, Montagne d’Ambre, 1,000 m alt, native 
forest, 14 Sept. 1961, H. St. John 26,578 
(bish). 
specimens examined: Madagascar?, C. 
Gaudichaud (FI, P) ; Madagascar, 1903, de 
Vilmorin (FI). 
discussion: P. connatus is a member of the 
section Mammillarisia, as is its closest relative, 
P. vanDamii Martelli & Pic. Ser., a species of 
Madagascar which has the peduncle 18-20 cm 
long; phalanges 35-40 mm long, 20-28 mm 
wide, ( 2 )-3-4-( 5-7) -celled; endocarp 11- 
12 mm long, the apex irregularly convex; and 
the leaves 40 cm. long, 2-5 cm wide. P. connatus 
has the peduncle 8 cm long; phalanges 33- 
35 mm long, 16-21 mm wide, 1-3-celled; endo- 
carp 20-23 mm long, with a long, conic, 
central apex; and the leaves 90-109 cm long, 
2- 2.3 cm wide. 
The binomials Pandanus acuminatus Hort. ex 
Wendl. and Vinsonia acuminata Gaud, ex 
Warb. were both nomina nuda. In the her- 
barium at Paris is a specimen with an original 
label by Gaudichaud, "Vinsonia acuminata 
Ch.G., mss. PMadagascar ? ?” It consists of six 
loose, somewhat eroded phalanges that well 
match those of P. connatus . A duplicate of this 
consists of 5 x /2 phalanges (FI). On the voyage 
of La Bonite, Gaudichaud obtained most of his 
Madagascar specimens by gift from A. Perville, 
formerly a gardener at the Paris Jardin des 
Plantes, later a voyager to the Seychelles and 
Nosy-be, and then a colonist in Madagascar. 
The new epithet is the Latin adjective con- 
natus, joined or united, and is given with refer- 
ence to the connate carpels.
