Jar, 4-cleft,segments rolled back spirally, stamenbearing at 
the top. Anthers protruded. Germen with two ovula. 
Stigma subulate (awl-shaped). Hypogynous glandules 
(small glandular bodies situated under the pistil) 4, some- ~ 
times distinct, sometimes connected. Receptacle flat, 
chafiless (without pale, the bractes of an aggregate inflo- 
rescence). Follicles* coriaceously woody, unilaterally dehis- 
cent, one-celled, somewhat cuneate (wedge-shaped), spear- 
pointed on one side of the top, bicornous on the other, or else 
with a pointless top, or in some instances echinated (beset 
with prickles). The species constitute a group of beautiful 
shrubs with leaves in whorls of threes and generally quite 
entire. ~ 
Formosa is distinguished from the rest by 7-flowered 
involucres, having the interior leaflets even with the corolla, 
hairy styles, follicles spear-pointed on one side bicornous 
on the other, linearly lanceolate spear-pointedly tipped 
leaves which are rolled back at the edge. 
In a luminous exposition of the nature of the inflo- 
rescence in Composite, Mr. Brown makes the following in- 
cidental mention of Lamzertra. “ In all the known species 
of this genus the leaves are verticillate, and uniformly in 
threes: in formosa and inermis the involucrum constantly 
contains seven flowers, while in uniflora it is reduced to one — 
flower. The seven flowers of the former species I consider 
as made up of two verticilli, in number of flowers cor- 
responding with that of the leaves, and of a single central or - 
terminal flower; to which terminal flower wniflora appears 
to be reduced.” Brown in trans. linn. soc. 12. 100.

* When, in another part of this work, we defined follicle, ‘an in- 
dehiscent scedvessel ;” we regarded ‘ dehiscence’ as technically limited to 
the symmetrical disjunction of the valves of plurivalyular seedvessels, and not 
comprehending the one-seeded opening of the univalvular kinds, But we 
were wrong.
