FLORAE MALESIANAE PRECURSORES XXIII THE GENUS RHODODENDRON IN MALAYSIA

In this revision of the Malaysian species of the genus Rhododendron L. 261 species and 55 varieties and forms have been distinguished, of which 96 species (some obviously hybrids) and 29 varieties are described as new; 10 species have been reduced to the rank of a variety or form, and 67 species, varieties, or forms have for the first time been regarded as synonym. In the keys to several subsections or series the extra-Malaysian species are included.

The Genera Sarcochilus R. Br. and Pteroceras Hassk. (Orchidaceae) with Notes on Other Genera Which Have Been Included in Sarcochilus

The genus Sarcochilus, established by Robert Brown in I8Io for a single Australian species, S. falcatus, was later made to include a very heterogeneous mixture of other species. The work of distinguishing natural genera among such of these species as occur in Malaysia was largely accomplished by the late J. J. Smith. In so doing he restricted the use of the name Sarcochilus to a particular group of Malaysian species with which Bentham and others had associated S. falcatus R.Br. In the preparation of my book on the Orchids of Malaya (1953) I also used the name Sarcochilus in this sense. Recently however V. S. Summerhayes called my attention to the fact that S. falcatus differs in some respects from the Malaysian orchids which Smith and I have included in the genus Sarcochilus. I therefore examined living plants of S.falcatus and also of two other Australian species in cultivation at Kew, and agree with Summerhayes that they are generically distinct from the Malaysian species in question. The present paper is an attempt to characterize the two genera and to establish the correct generic name for the Malaysian species; also to typify the various other genera which at one time or another have been included in Sarcochilus and to give an opinion on their status.

A Review of the Reptile Chiggers, Genus Fonsecia (Acarina, Trombiculidae), with Descriptions of Two New American Species

The genus Fonsecia was proposed by Radford (1942) to include 2 Brazilian chiggers, Trombicula ewingi Fonseca, 1932, the type species, and T. travassosi Fonseca, 1936. The principal generic character was the modified, stubby, peglike anterolateral scutal setae. A third species, F. coluberina Radford, 1946, extended the range of this group to India. The report of all 3 from only snakes suggested reptilian host specificity of Fonsecia larvae. The distinctness of this group is well established, although authors have regarded it variously as a genus or as a subgenus of Trombicula. The larvae of the type species of Trombicula, T. minor, is unknown; however, Audy (1954) has presented convincing evidence that it is small, a parasite of bats, and closely related if not identical to one of several bat-infesting species in Malaysia. None of these appears to be related to Fonsecia species below the subfamilial level. Furthermore, 4 additional species, of which 2 new ones are described below, are now included in the group. All these are limited to reptilian hosts, and 2 are recorded from lizards as well as from snakes. For these reasons, therefore, we follow those authors (see under generic references below) who have accorded full generic status to the group. The genus is redescribed as follows:

FLORAE MALESIANAE PRAECURSORES XIV* A REVISION OF THE GENUS DIPLYCOSIA (ERICACEAE)

In this revision of the nearly exclusively Malaysian genus Diplycosia Bl. 84 species and 12 varieties are distinguished, of which 17 new Malaysian species resp. 8 varieties and 2 extramalaysian species are described; 4 species have been reduced to varietal rank, 1 new name has been proposed. An index to specimens has been added.

FLORAE MALESIANAE PRAECURSORES XV*THE GENUS GAULTHERIA IN MALAYSIA

In this revision of the Malaysian species of the genus Gaultheria Kalm ex L. 24 species and 9 varieties resp. forms are recognized. Among the new taxa described are 9 species and 1 variety. The localities of the revised material are given in detail. An index to specimens is added.

NOTES ON MALAYSIAN CYPERACEAE-II *

Since 1884 the name Cyperus zollingeri Steud. has been misapplied to a common tropical species, the correct name of which is C. tenuieulrnis Boeck.It appears that C.rubroviridis Chermez.(1919) and C. ramosiiKiikenth.(1925) are synonymous with C. zollingeri Steud. (1855).Cyperus leucoeephalus Retz, and C. pulehellus R. Br. are treated as specifically distinct.The Philippine record of C.leucoeephalus is referred to C. pulehellus.A tentative arrangement of the Malaysian material of the polymorphous Cyperus sanguinolentus Vahl is given.Mariscus maritimus Miq. is reduced to Cyperus dubius Rottb.,C. pulcherrimus f. retiglwmis Valck. Sur. to the species.The previous Malaysian records of Cyperus stenostachyus Benth.and C. polystachyos 1. longispiculatus Valck. Sur. are erroneous. A survey of the distribution of some Malaysian species is given.The following new combinations are made: Cyperus trialatus (Boeck.) Kern; C. sanguinolentus ssp. melanocephahis (Miq.) Kern, ssp.cyrtostachys (Miq.) Kern, and ssp. teijsmannii (Miq.) Kern.

THE GENUS TETRACERA (DILLENIACEAE) IN THE EASTERN OLD WORLD

1. An account of the genus Tetracera L. in the eastern Old World (Asia, Malaysia,Australia, New Caledonia) is given. The Malaysian species have already been in cluded in the revision of the Dilleniaceae in Flora malesiana (I 4: 141-149. 1951). 2. The main part of the present paper consists of a key to the species, followed by a systematic treatment of the 15 species admitted for the region. 3. Latin diagnoses are given for three new subspecies under Tetracera asiatiea (Lour.) Hoogl. and two new varieties under Tetracera nordtiana F. Muell. 4. A number of species are reduced either to the rank of variety or to synonymy. 5. Distribution-maps are provided for the species of which a relatively large number of specimens has been studied.
