104 NOTES ON HUMIRIACES. 
1. S. Amazonica (Mart. Nov. Gen. et Sp. vol. ii. p. 146); glaberrima, 
foliis oblongis ellipticisve acuminatis, ovario depresso-globoso 5- 
sulcato.— Folia 4—6-pollicaria, leviter crenata, demum crasso-coriacea. 
Pedunculi nunc pollice breviores, nunc 2-3-pollicares, cymis nunc 
laxiuseulis paucifloris nune amplis dense multifloris. Flores fere 
2 lin. longi, glaberrimi. Discus (squamis bifidis) fere 10-lobus. 
This, according to Mr. Spruce, is a common tree along the Amazon, 
about Santarem and Obidos, on the margins of moist forests, and 
known to the Brazilians under the name of Uaaud. Martius found it 
on one of the channels of the same river, and Gardner’s specimens, 
n. 3047, from the province of Goyaz, appear to belong to the same 
species. The young leaves are of a deep red. The peduncles vary 
much in length; Martius describes them as of the length of the pe- 
tioles. Ihave never seen them so short as that, although they are 
sometimes not much longer, whilst some are full three inches long. In 
other respects Martius’s — agrees well. The fruit is said to 
be good eating. 
Some of Mr. Spruce’s specimens have several of the flowers trans- 
formed into ovate coloured leaves, about 5 lines long, so as to give to 
the cyme the appearance when fresh of a bunch of two or three small 
double pink roses. 
2. S. Guianensis, sp. n.; ramulis inflorescentiaque puberulis, foliis 
oblongo-ellipticis breviter acuminatis, ovario ovato-globoso vix 
sulcato. 
From British Guiana (Rob. Schomburgk, 2nd coll. n. 574, Rich. 
Schomburgk, n..842). It is certainly very near to S. Amazonica, but 
besides the leaves being usually shorter in proportion to their breadth, 
and the pubescent inflorescence, the flowers are considerably smaller, 
the filaments broader, the disc consists of five nearly distinct truncate 
scales, and the ovary, scarcely furrowed, is more gradually attenuated 
into a much shorter style. The fruit is unknown.
