sharp whitish diaphanous hairs; carpels together with the styles about as long as the 
stamens, the ovaries rufous-sericeous, the styles club-shaped, chocolate brown, micro- 
scopically granular on the surface, the terminal stigmas swollen at the time of polli- 
nation and minutely tuberculate; fruit (immature specimen collected by Poiteau) 
ovoid or heart-shaped, muricate with sharp fleshy points, like a minature fruit of 
A. muricata in appearance, 2.5 cm. long, 1.8 cm. in diameter; seeds small, ovoid, 
somewhat compressed and bearing a swollen caruncle at the base. (PLateEs 85, 86,

Candolle; Karouany, 1855, P. Sagot 7; without definite locality, 
1817-1822, Poiteau, photograph of specimen in Kew Herbarium,

Annona sericea, though normally 3-petaled, has sometimes 3 
additional inner petals. These when present are linear-lanceolate 
in shape and are sometimes imperfect, as in abnormal flowers of 
A. globiflora. They are alternate with the 3 outer petals and 
appear to close the seams between them, as if to protect the 
essential parts of the flower from moisture, as in the case of A. 
angustifolia Huber, a closely allied shrub of Brazil, regarded by 
Martius as a narrow-leaved variety of A. sericea (A. sericea var. 
angustifolia Mart.).? These 6-petaled forms appear to connect 
A. sericea with A. paludosa Aubl., in which the flowers are 
Fig. 42.—Fruitof An- normally 6-petaled. Annona paludosa further resembles A. 
spe Natural sericea in the soft, velvety lining of its leaves and its small, 
ovoid fruit covered with fleshy prickles, very much like the fruit 
collected by Poiteau in French Guiana (fig. 42).* The two species are undoubtedly 
distinct, both of them being recorded as common in French Guiana, where they are 
known by the common name guimamé. According to Sagot A. sericea is distinguished 
from A. paludosa as guimamé savane. The latter is known simply as guimamé, or as 
corossol sauvage (from the resemblance of its fruit to a miniature soursop).4 
’ Patris, J. B. “‘Médecin et botaniste du roi, et conseiller au Conseil-supérieur de 
Cayenne,’’ for whom the genus Patrisa was named by Richard. ‘He collected with 
great zeal in French Guiana about the year 1795. His collection, which probably 
included twelve or fifteen hundred species, and which has been estimated at two thou- 
sand, on account of duplicates, was presented by the chevalier Turgot to Lhéritier 
and was acquired by A. P. de Candolle, when he purchased Lhéritier’s herbarium 
Patris’s plants, which form more than half the Guiana species of the original herbarium 
of the Prodromus, bear neither the signature of Patris nora record of the exact locality 
in which they were collected. Patris was in communication with de Rohr and Ro- 
lander. His specimens were prepared with great care, and were probably represented 
by either a single sheet or by twoor three.” Sagot, Catalogue des Plantes de la Guyane
