from Bauh. Pin. 159, where it stands in contrast with an u Ammi 
parvum foliis focniculi ” ( = Sison Ammi L.) and where it clearly 
seems to designate the following var. of A. mqjus , viz. 
(3. isophylla ; all the l. 2-3-pinnatisect with linear-lanceolate 
or linear gashed or serrate Ifts. — A. majus foliis plurimum incisis 
et nonnihil crispis C. Bauh. Pin. 159. A. majus var. A. Desf. 1. c. 
A. majus var. tenuifolia &c. Brot. 1. c. 444. A. intermedium DC. 
iv. 113 P — Mad. reg. 1, 2, ■£. Occasionally here and there with a, 
into which it gradually passes. Equally spreadingly branched 
and with quite the habit of a, but mostly perhaps somewhat 
larger and from 1 to 2 ft. high, having the lower st.- or root-1, 
decompound with their segm. finely linear-lanceolate and serrate 
like the upper. 
y. tenuifolia ; root and lower st.-l. as in a , upper 2-3-pinnati- 
sect with linear-lanceolate or linear nearly or quite entire Ifts. — 
Mad. reg. 1, P ta de S. Louren^o, on the dry exposed rocky 
sunny slope of the Penedo do Saco. — This seems to differ from 
A. gtaucifolium L. (Vill. Dauph. ii. 592 ; DC. iv. 112 ; Guss. FI. 
Sic. i. 317) described as having the lower as well as upper 1. 
(as in /3.) decompound or 2-pinnatisect with the Ifts. linear-lan- 
ceolate or linear but very entire or only 1-2 -toothed instead of 
regularly serrate, — merely as a. does from [3. in the simply pin- 
nate or 2-pinnate root-1, with broad leaflike Ifts. It is altogether 
a more dwarfish slender pi. of humbler more straggling growth 
than a. or /3, with the umbels about 10-rayed, the gen. invol. 
scarcely half the length of the rays and the fine linear entire 
segm. of the upper 1. ending in a pale w. awn or point or some- 
times in 2, 3 or 5 bristle-pointed teeth. It is evidently a mere 
depauperated state of a, grown in a maritime hot dry sunny spot. 
2. A. pitocEituM Lowe. 
Subglaucous or greyish; st. round tall straight stout erect 
virgate branched upwards only and mostly above the middle, 
branches erect little developed and subordinate to the distinct main 
st. throughout ; 1. heterophyllous, lower st.-l. pinnate or 2-pinnate 
with long petioles and leanike simple roundish-oval, broadly ob- 
ovate, oblong-obovate, or cuneato-lanceolate, sharply finely and 
evenly cartilaginously serrulate Ifts.; upper 1. finely decompound 
2-3- or even 4-pinnatisect sessile on the sheaths of the petioles, 
with fiat linear or linear-lanceolate partly entire partly gash- 
toothed or serrate Ifts., each ultimate tooth or segment cuspi- 
dately awned ; umbels opposite the 1. on long stalks 30-50 -rayed, 
the rays (gen. and partial) scabrous spreading, the former erect, 
latter subincurved in fr. ; gen. inv. several conspicuous nearly or 
quite as long as the rays , setaceo-pinnatifid or trifid, partial simple 
linear with w. membranous margins and produced into fine se-
