HEMITOMES, nov. gen. MONOTROPEAEUM. (By A. Gray.) 
Calyx disepalus, bracteoliformis. Corolla tubuloso-urceolata, 4-5-loba, post anthesin mar- 
cescens, lobis patentibus intus villosulis. Stamina hypogyna, 8 vel 10 : filamenta filiformia, 
superne barbata: antheraj basifixae, glanduia parva apiculata, dimidiatim unilocularis ; nempe, 
loculo fertili oblongo-lineari longitrorsum dehiscente, altero ad costain billamellatam reducto. 
Discus nullus. OYarium ovoideum, pseudo-quinqueloculare, nempe placentae 4 bilamellatae 
videntur, divaricatse, et inter se coalitae circum locellum centralem, extus intusque creberrime 
ovuliferie. Stylus elongatus: stigma depressocapitatum, integerrimum, umbilicatum, per- 
vium. Eructus ut videtur carnosus evalvis.—Rhizophytum brunneum, carnosum ; caule sim- 
plici squamato; floribus sessilibus in capitulum terminate congestis bracteatis. 
Hemitomes congestum. (Plate XIII.) Upper Des Chutes valley ; September. 
The addition of a new genus to the small order or sub-order Monotropece , is a matter of no 
small interest; and this, founded on a fragmentary, but yet an adequate specimen, is the third 
which has come to our knowledge from the Pacific border of the United States.* The plant 
has much the aspect of a Monotropa of the section Bypopitys ; but is remarkable for bearing its 
flowers in a dense, terminal, nearly hemispherical bead. Each flower is subtended by a scaly 
bract, nearly like the scales of the stem, and about as long as the corolla. The outer flowers 
appear to be all tetramerous and octandrous, like the lower ones of Bypopitys , but some of the 
inner ones have a 5-lobed corolla, and, I believe, 10 stamens. A pair of narrowly-linear 
persistent lateral bractlets represent the calyx. The scarious-membranaceous corolla is urceolate-

near the same time published in California by Dr. Kellogg, under the name of Pterosporopsis,) and Allotropa, the single known 
species of which Allotropa virgata, Torr. & Gray, ined. was gathered on the Cascade mountains of northern Oregon, by Dr.
