322 MESSRS. LACE AND HEMSLEY ON THE 
Although the shape of the pod is very different, and the seeds 
are uniseriate, the present plant is so like Leptaleum filifolium 
in other characters that we have no hesitation in placing it in the 
same genus. 
Dr. Stapf suggests that Zeptaleum can hardly be maintained as 
generically distinct from Malcolmia. 
DESCRIPTION OF PLATE XXXVIII. 
A plant of a hamatum, Hemsley & Lace, natural size. 
Fig. 1, a flower; 2, the genitalia; 3, a seed ; 4, embryo. All enlarged. 
Gypsophila ($ Eugypsophila-Capitatæ) lignosa, Hemsley 4 
Lace, n. sp. 
Frutex nanus, dense ramosus, ramulis graciliusculis ultimis 
elongatis floriferis minutissime puberulis cortice albido vel viridi. 
Folia pauca, opposita, internodiis sepius brevibus, vel in ramulis 
brevibus lateralibus conferta, teretia, crassiuscula, acuta vel fere 
spiniformia, maxima vix polliearia, sed sæpius semipollicaria, 
hispidula, glauca. Flores parvi, absque staminibus, vix 3 lineas 
longi, sessiles, densissime capitati, capitulis solitariis terminali- 
bus longe pedunculatis 4-6 lineas diametro; bracteæ ovato- 
oblongæ, obtuse vel subacute, floribus dimidio breviores, parce 
puberulæ, medio incrassate, marginibus membran aceæ, interiores 
minores et omnino membranacee ; calyx herbaceus, obseurissime 
puberulus, subcylindricus, sursum leviter expansus, breviter 
5-fidus vel 5-dentatus, dentibus latis subobtusis ; petala anguste 
spathulata, apice rotundata, calycem paullo superantia ; stamina 
ut videtur longiuscule exserta; ovarium circiter 8-ovulatum, 
stylis 2 inclusis. Capsula deest. 
Ziarat at 9000 feet. 
Allied to G. capitata, Bieb, and G. spherocephala, Fenzl; 
differing from both in having terete leaves, and solitary heads of 
flowers ; the flowers much smaller and looser than those of the 
former species ; and the whole plant much more shrubby than 
the latter. The flowers also differ considerably in detail.
