upper ; primary lateral nerves about 8 on each side of the midrib, 
rather slender, curved-ascending, obscurely anastomosing; pe- 
tioles stout, 1 cm long or less. Panicles arranged near the apices 
of special branches, these branches up to 3 cm long, usually 
marked with large petiolar scars, bearing near their apices sev- 
eral reduced leaves and several slender panicles, the reduced 
leaves mostly less than 6 cm long and 1 cm wide, the panicles 5 to 
10 cm long, narrow, rather many flowered. Male flowers pink or 
white, 5-merous, about 5 mm in diameter, their pedicels 4 to 
5 mm long. Calyx 5 mm in diameter, prominently punctate, 
shallowly 4- or 5-lobed, the lobes not reaching the middle, broadly 
ovate, obtuse or rounded, glabrous. Corolla 5-lobed, the lobes 
united for about their lower one-fourth, elliptic-ovate to oblong- 
elliptic, rounded, 2 to 2.5 mm long, prominently glandular. An- 
thers about 1 mm long, not glandular. Rudimentary ovary about 
1.5 mm long, narrowly oblong, glandular. Fruit subglobose, 
bright red when mature, nearly or quite 1 cm in diameter, slightly 
longitudinally ridged when dry. 
R. C. McGregor 558 , October, 1911, in forests, Upi road, locally known 
as otud or otot. 
A well marked species more closely allied to the Philippine Discocalyx 
cybianthoides Mez than to the Marianne D. ladronica Mez. but very dif- 
ferent from both. The type of the latter species may have been from 
Guam, as it was collected in the Marianne Islands by Gaudichaud. This 
is undoubtedly the plant recorded by Safford p. 295 as Icacorea sp. 
No representative of the Primulaceae is known from Guam. Lysimachia 
mauritiana Lam. cited from the Marianne Islands by Pax & Knuth, 54 coll. 
Gaudichaud, may have been from Guam, but was probably from Tinian 
or Rota. At any rate it will probably be found in Guam.

mens collected in Yap, Caroline Islands, a duplicate of the type being in 
the herbarium of the Bureau of Science. Very close to S. jerrugineum
