JUTTIFERAE 
Dr. Bassett Maguire has submitted the following criti- 
‘al notes on the genus Lorostemon. 
In an area near Mandos, where for more than a cen- 
tury the famous botanical explorers of the Amazon Basin 
(Martius, Spruce, Ule and others) had made headquarters 
for long periods of time, Ducke discovered a remarkable 
stand of small trees to which he gave count, “*. . . ving- 
taine d’arbres adultes. ..°° From specimens collected 
there, he described Lorostemon bombaciflorum which he 
proposed (Ducke, A. in Arch. Inst. Biol. Veg. 1 (1985) 
210) as the type of a new monotypic subfamily, the 
Lorostemonoideae of the Guttiferae. Principal criteria 
upon which the new subfamily was based were: 1, the 
arrangement of the anthers, five each in five concrete un- 
divided phalanges; and, 2, the ovary borne on a long 
gynophore similar to that of many capparids. Arrange- 
ment of the stamens in five phalanges is, of course, not 
unique in the Guttiferae, being generally characteristic 
of the genera of the Moronobeae. But the stipitate ovary 
base was not otherwise known for the family. 
I have before me an isotype of Lorostemon bombaci- 
florum: Ducke 28768 (NY)—and two additional sheets, 
Ducke 944 and 1200, obtained from the type locality in 
1942 and 1948, respectively. All three collections are 
faithful to the original description. 
Now, Schultes and Cabrera have made three addi- 
tional collections of Lorostemon, but from the region of 
the Rio Apaporis, an affluent of the Caqueta or Japura, 
some 800 miles to the west and north of Mandos. Two
