CoRRIGIOLA PSAMMATROPHOIDES, N. sp. 
Annua, glabra, dense cspitosa, caulibus stramineis erectis multoties 
dichotome furcatis, folis parvis distantibus oblanceolatis alternis vel 
oppositis, floribus copiose umbellatis pedicellis brevissimis, perianthii tubo 
brevissimo segmentis oblongis viridibus margine albis, fructu globoso- 
triquetro brunneo glabro. 
An erect densely tufted annual herb, with slender straw- 
coloured stems 3—4inches long, many times dichotomously forked, 
with intertangled erecto-patent branches. Leaves few, distant, 
glabrous, 4 in. long, narrowed from the middle to the base, 1- 
nerved, usually alternate. Flowers in copious dense umbels in 
the forks and at the end of the branches, mixed with leaves like 
those of the stem ; pedicels very short. Perianth not more than 
3 line long, green, glabrous, with a short tube and five oblong 
imbrieated segments with a distinct white edge. Fruit globose- 
triquetrous, hard, brown, nearly as long as the perianth.—Central 
Madagascar, Baron 2153! Habit of Psammatrophe, an endemic 
Cape genus of Ficoidee. This adds the order Z/lecebracec to the 
Madagascar flora. 
CvATHULA (§ POLYSCALIS) SPHJEROCEPHALA, n. Sp. 
C. eaulibus erectis dense pilosis, foliis petiolatis cordato-ovatis acutis 
utrinque pilosis, floribus albis basi lanosis in glomerulos globosos terminales 
aggregatis, fertilibus perianthii segmentis 5, exterioribus 2 navicularibus 
dorso l-nervatis, 3 interioribus planis lanceolatis rigidulis dorso nervis 
tribus viridibus percursis, sterilibus lanceolatis apiculatis apice rectis vel 
glochidiatis. 
A tall erect branched perennial herb, with densely pilose 
angled stems. Leaves in distant pairs; petiole 3-1 in. long ; 
blade 2-3 in. long, broad ovate, cuspidate, shallowly cordate at 
the base, moderately firm in texture, dull green on both sides, 
thinly hairy above, densely villose all over beneath. Flowers in 
globose heads 3—} in. in diam., sessile in the axil of the topmost 
pair of leaves. Fertile perianth } in. long, the two outer seg- 
ments navicular, white with a 1-nerved greenish-brown keel ; three 
inner segments flat, lanceolate, firm in texture, with a white 
border and green centre. Barren flowers as long as the fertile, 
lanceolate at the base, more or less distinctly cuspidate, with a 
straight or hooked tip.—Central Madagascar, Baron 1135!
