Monotropsis has a calyx of 5 distinct sepals and a sympetal- 
ous corolla. It has also a manifest disk, which is described by 
earlier authors as 5-cleft (1), (2), (8), (4), (5) and by later 
authors as 10-crenate (8), (10), (11), (15), repectively 
10-toothed (138). A detailed statement on the position of 
stamens by Rafinesque (3) reads: “Stamens 10, a pair be- 
tween each angle of the nectary.”’ The anthers are in general 
described as clavate-saccate (1), (5), 2-saccate (6), (18), 
awnless .(6),. (8):,..¢9).,. €11), 12), (18),..(15),.. d-eelled -(2),

by pores (2), (4), (5), (8), (10), (11), (12), horizontal in 
the bud (8), (10), (11). Besides there are two statements by 
Gray (7) which are worth citing because the only ones refer- 
ring to a transversely 2-saccate character of the anther; they 
read: ‘The anthers. ... in the flower bud are horizontal, so 
that one cell stands directly above the other’* and 
“antherae... in alabastro transversae.” 
On comparing the description of the ‘Alabawia. plant with 
the above compilation the following result is obtained. In 
both the Alabama plant and Monotropsis, the calyx consists 
of a complete series of distinct sepals and a sympetalous 
corolla. Both have a manifest hypogynous disk which is 
5-lobed, with the lobes manifestly emarginate in the Alabama — 
plant, and most probably so in Monotropsis. I base this 
assumption on the fact that the earlier authors describe the 
* The figured anthers in Britton & Brown’s “Illustrated Flora” are 
not transversely saccate. Anthers like this cannot be expected to have 
one sac stand directly above the other in the bud except one supposes 
a twist of the filament. .
