 Obs. ~ ■ 



R. W. Ic). 



Roth describes his plant as having very small 

 flowers, a little larger than a mustard seed, and the corol- 

 la 4-cleft. The flowers of my plant are certainly small 

 but larger than his and are 5-lobed. Notwithstanding 

 these discrepancies,! suspect we refer to the same plant, 

 with this difference, that my drawing was made from 

 fresh specirnens, his description from dried ones. The 

 figures of this plate however afford no criterion to judge 



of size as they are all magnified. 



CXVIII.— BORRAGINE/E. 



mid 



Ihis, as it now stands m De Candolle's Prodromus, is an order of great extent (upwards of 

 1000 species) and compkxitj, inasmuch as they (DC, father and son) having brought 

 together as one what most other Botanists yiew as three distinct orders; namely CordiaceiE, 

 JLhrehace<E, and BorraginecB proper. To this extreme grouping Lindley is stronglv opposed, 



even goes so far as to place the first in his Solanal Alliance, the otlier two in his 

 ii.chial.^EndIicher takes a different yiew. He retains Cordiacece as a distinct order, but 

 unites hhretiace<B and Borraginece under the Linnean family name of JsperifolL Arnott, as 

 will be seen by a reference to his syllabus, preserves all the three, but places them in a 

 sequence In this article I intend following De Candolle, but so far as the pictorial illus- 

 trations ot the order can avail towards conveying a correct understanding of these different 

 views nothing will be wanting to enable every one, who may consult them, to judge for
