[370. C. Hartwegii, Boott in Benth. PI. Hartweg .—-

The specimen figured at Tab. DIX. is Hartweg’s original in 
Herb. Hooker. That represented in DX. is probably Eendler’s, 
from Venezuela. I have taken the synonyms from Dr. Boott’s last 
revision of the species as written up in Herb. Hooker, according to 
which it appears that he regarded Hartwegii and Mexicana as 
synonyms, and as a small variety of C. polystachya. — J. _D. JET.] 
[371. C. lasiochlsena, Kunth, Cyp. 485. (Tab. DXI.) 
Hab, Sardinia. 
I suppose that this figure represents an authentic specimen, 
and was made for this purpose. I find no specimen in Herb. 
Boott or Herb. Hooker, and no allusion to the plant in Dr. 
Boott’s MSS.— J. D. H] 
[372. C. Mexicana, Presl. (Tab. DXII.) Vide supra, 
370. 
This drawing was made from Galeotti’s specimens, n. 5734 and 
5721.] 
[373. C. physocarpa, Presl ( non Nees ). (Tab. DXIII.) 
The specimen from which this figure was made was placed in 
the covers with C. saxatilis, and evidently referred by Dr. Boott 
to this species, which bears the following ticket:—- 
“ C. puella ! Stigmas 2. Rocky Mountains, Drummond. 
Marked C. membranacea, by Torrey and Dewey. Variat raris- 
sime spica feminea inferiore longissime pedunculata. An C.phy- 
socarpa, Presl.” 
The original C. physocarpa is a native of Nootka Sound.— 
J. D. H.) 
[374. “ C. purpurea, Boott.” (Tab. DXIV.) 
I find no specimen nor description of this species in Dr. Boott’s 
Herbarium or MSS., but after the name on the drawing is written 
“ Specimen Bonplandii,” in Spach’s handwriting.— J. D. Hi] 
375. C. sanguinea (Boott); spica elongata decompo- 
sita duplicato-racemosa sanguineo-purpurea, racemis re- 
motis mediis geminatis longe exserte pedunculatis erectis, 
spiculis 3-8 ovatis apice'masculis ad apicem peduncu- 
lorum alternatim dispositis ; bracteis vaginatis culmum 
subaequantibus; stigmatibus 3; perigyniis lanceolato- 
ovatis triquetris sensim rostratis, ore hyalino bifido ner¬ 
vatis scabris, margine serratis superne purpureis subre- 
curvis, squama ovata acuta vel mucronata purpurea
