OF A NEW SPECIES OF HAWORTHIA.

(Plate XXVI.) 
(Bead June 16, 1909.) 
Haworthia tbuncata, Schonl., n. sp. 
Radices carnosi elongati. Caulis brevissimus carnosus. Folia 2-5 stricte 
disticha 2-3 cm. longa medio circ. 17 mm. lata carnosa applanata ovato- 
deltoidea truncata suberecta leviter incurvula, apice faciem suboblongam 
medio constrictam tuberculis minutis rugosam exhibientia, supra apicem 
versus convexa longitudinaliter canaliculata tuberculis minutis rugosa infra 
vaginantia concava Isevia ad margines tenuiter denticulato-ciliata, subtus 
convexa medio longitudinaliter leviter canaliculata superne tuberculis 
minutis rugosa. Pedunculus erectus gracilis simplex filiformis, e basi vacue 
bracteatus incl. racemo laxo 20-25 cm. altus. Bractei ovato-acuminati 
membranacei 4-5 mm. longi pedicellis subaequantes. Perigonium c. 
10 mm. longum albidum obscure striatum tubo subventricoso segmentis 
bilabiatis. Stylus ovario triplo brevior. Capsula oblonga, triquetra, 8 mm.

This new species is very interesting from several points of view, on 
some of which I beg to offer a few remarks. It is evidently allied to the 
species which have been placed under the sections Venosce, Berger, and 
BetuscB, Haw.* 
In the first place, it is the only species of Haworthia hitherto known 
with bifarious arrangement of leaves. However, in the allied genus Aloe 
there are several species which show this arrangement, although the 
majority of species, when adult, have multifarious leaves, and in another 
genus, Gasteria, it is quite common. There is nothing to indicate whether
