I have not attempted to classify the specimens cited in their parti- 
cular varieties as quoted bv Sonder, as they appear to me to merge one 
into the other. Var. acuminata Sonder, I. c., p. 419, is probably the most 
distinet of these, of which specimens gathered by Zeyher on Table Moun- 
tain, and Wright at Simonsbay, obtain at Kew. It was in cultivation as 
for back as 1810. Bolus (no. 6871) may probably represent var. virgata 
Sonder. Bolus (no. 4790) and Mac Owan (no. 206 partly) are forms of 
var. obtusata. A. polyphylla Presl. Bot. Bemerk. 32, is a synonym of the 
species, not quoted by Sonder. 
59. Agathosma Lambii Dümmer, nov. spec. 
Fruticulus 0,3—1 m altus, habitu ericoideus, ramulis verticillatim 
positis subfastigiatis saepe simplicibus bruneis parcipubescentibus densi- 
foliatis. Folia imbricata vel patulo-ascendentia, perbreviter petiolata, 
ovata vel late ovata, subcuspidata, basi rotundata vel subcordata, 2—2,5 
mm longa, circiter 1,5 mm lata, subcoriacea, utrinque glabra, supra 
complanata vel concavula, subtus costato-carinata, apicem versus valde 
inerassato-carinata, glandulis fuscis 4—6 conspersa. Umbellae numerosae, 
subcapitatae, multiflorae, hemisphaerica, 0,8—1,3 cm diametro, floribus 
albis (fide Burchell); pedicelli breves, circiter 2 mm longi, glabri, brac- 
teolis medio dispositis obtuse subulatis 0,7 mm longis glabris. Calyx 2—- 
2,2 mm longus, extra glaber, segmentis oblongo-triangularibus obtusis 
dorso valde carinatis margine parciciliatis mox glabris, Petala longissime 
unguiculata, toto 4 mm longa, lamina fere orbiculari 1,9 mm diametro 
ungui inferne patenter piloso. Stamina 4 mm longa, glabra; staminodia fili- 
formia, 3 mm longa, medio patenter pilosa, ceteris glabra, glandula apicali 
notata. Ovarium superne albo-parcistrigillosum, stylo crasse subulato glabro. 
Coast Region. Mossel Bay Div.; on hills between Mossel Bay and 
Zout River, Nov. 1, 1814, Burchell, 6320! (Herb. Kew). 
The facies of this plant is essentially that of forms of A. imbri- 
cata Willd., but the relatively smaller leaves, their glabridity and the 
lack of any marginal ciliation whatsoever preclude its conspecificity. 
In its floral characters it appears to be identical with the latter species. 
The species is named in compliment to Mr. J. Lamb, a zealous botanical 
collector, residing on the Cape Peninsula.
