A New Species

Kalanchoe torrejacqii (Crassulaceae subfam. Kalanchooideae) is described as a new phyllo-bulbiliferous species. It occurs in the Namorona River valley, near Ranomafana, southern Madagascar. Differences between K. torrejacqii and the partially sympatric K. laxiflora are discussed and the new species is contrasted with representatives of the K. rosei complex with which it shares some similarities. Kalanchoe torrejacqii is the most northern pink-flowered species among other such species that belong to the recently described K. sect. Invasores, to which K. laxiflora and representatives of the K. rosei complex also belong.

This is the first detailed taxonomic study of the genus Navicula in the Krasnodar Territory of the Caucasus region, Russia. During the study of the genus in waterbodies of the Adegoy River valley 15 taxa were recorded. Two species, N. adegoyensis sp. nov. and N. pseudocryptofallax sp. nov., are described as new to science. Their morphology is studied by light and scanning electron microscopy, and comparisons with morphologically similar species are provided. The use of the name N. avenacea for N. lanceolata sensu auct. is discussed. Navicula diversity was higher in the Adegoy River than in pools elsewhere in the river valley.

Three New Species

Three new species of Iridaceae are described from the Bokkeveld and Roggeveld Escarpments.  Ixia amethystina. a member of section Dichone, is endemic to the edge of the Roggeveld Escarpment. It shares an unusual, inclined spike that is nodding in bud with  I. trifolia but is distinguished by its blackish purple (not yellow) anthers, narrower leaves 1.5-2.0 mm wide, medium-textured corm tunics that form a distinct neck at the base of the stem, and short style branches 2.0-2.5 mm long.Moraea marginata. another Roggeveld endemic, is a member of section Polvanthes and florally similar to M. fistulosa and M. monticola but differs in its linear, channelled leaves 5-7 mm wide, with unusual, thickened margins. Romulea singularis. from the edge of the Kobee River Valley in the Bokkeveld Mountains, is a member of section  Ciliatae. It is unique in the genus in its narrowly funnel-shaped, mauve to purple flowers with slender perianth tube 10-11 mm long, and unusually long filaments, 8-9 mm long, inserted in the lower half of the tube.

Rule Ordering ◽  
Mackenzie River

Recent changes in Hare, an Athapaskan language of the lower Mackenzie River Valley, require that a rule of epenthesis be ordered in two places in the grammar. The original rule is ordered before a rule of vowel raising. In the innovative dialect of Hare, part of the environment for this epenthesis rule is revised and it must be ordered after the raising rule.

Two recently discovered species of Lachenalia from South Africa, Lachenalia barbarae from the Overberg district of the Western Cape and Lachenalia adamii from the Bokkeveld escarpment of the Northern Cape, are described. In addition, details of the rediscovery of two species previously thought to be possibly extinct in the wild, Lachenalia martleyi from the Overberg district in the Western Cape and Lachenalia macgregoriorum from the Bokkeveld plateau in the Northern Cape, are provided, as well as a range extension for the critically endangered Lachenalia moniliformis from the Breede River Valley in the Western Cape.
