Chemical Biologist of the Bureau of Plant Industry at Washington, 1909-15; since 1915 Professor of Botany at Michigan University and Director of the Botanic Garden there; in 1918 in the employ of the U.S. Rubber Co. at Kisaran, Asahan, Sumatra, as Botanist. In 1926-27 he made a collecting trip to Formosa and Sumatra under the joint auspices of the University of Michigan and the Smithsonian Institution; in later years he made several expeditions in America; in 1935 Exchange Professor of Botany, Univ. of the Philippines; in 1940 he left on a U.S.D.A. mission to the Indomalaya and the Philippine Islands. Retired in 1955.

The plant genus Siraitia was named after him (in Silo Maradja he was named Si Rait as an adopted tribal brother of the chieftain) and many plant species.


Collecting localities:

Sumatra East Coast. 1918. Asahan and on the Karo Plateau.-1926-27.1 Dec. 25, 1926 arriving in Asahan, field-work from Jan. to July 1927, operating from Silo Maradja: several weeks at Loendoet, south of Asahan River; hurriedly through the back of Asahan up over the mountains to Toba; ascent of Dolok Soeroengan; two trips to the Karo Plateau, B(e)rastagi, Si Naboen (= Sinaboeng) and Sibajak volcanoes, Deleng Piso-Piso and Deleng Baroes, Deleng Koetoe, Deleng Singkoet-1935. Mindoro (Apr.), Luzon (July), Mt Iraya, Batan I. (July), Philippines (Oct. 31-Nov. 5) : Dalupiri Isl., Babuyan Isl., and probably other collecting trips to various parts of the islands in the same year.-1940. Philippines. Collecting at least at Del Monte, Bukidnon, Mindanao (Dec. 6).



The Sumatra collection of 1918,2 ± 500 nos, was made by native collectors under the direction of C.D. Larue and H.H. Bartlett.

Merrill distributed the sets: Herb. Manila [PNH], Leiden [L], Kew [K], U.S. Nat. Herb. Wash. [US] (247), Gray Herb. of Harv. Univers. [GH]; some in Copenhagen [C]. As the collection was sent to Manila there were two series of numbers, those of Galoengi (see there) who collected in Asahan (nos 1-70) and the Karo-lands (nos 71-338), and those of Ramat alias Bidin Sirait Holboeng, collected in Asahan (nos 1-165). These 2 series were thrown together at the Bur. of Science, where Galoengi’s collections were numbered 1 to 330, without maintaining correspondence between his original numbers and the new numbers. Bidin’s collection continued the numbering from 331 to 495. A few plants collected by Bartlett near Balige, Toba, were included in the series as nos 496 to 502. Numerous mistakes were made in transferring the data, so botanists who intend to cite the specimens are urged to follow the data of the original hand-written labels. The set sent to the Nat. Herb. Wash. [US] lacks the original labels and the Karoland plants are labelled incorrectly as from Asahan.

The Sumatra collection 1926-27,3 ± 2400 nos (numbered above 6000); best sets in U.S. Nat. Herb. Wash. [US], Univers. of Michigan [MICH], N.Y. Bot. Gard. [NY] and Field Mus. Chicago [F] (522 dupl.).

In 1928 the native collector Rahmat si Boeea (see there, and under Hamel) made a Sumatra collection in the employ of Bartlett.

Also dupl. in Herb. Sing. [SING] (pres. 1935); in Gray Herb. [GH]: 20 Philip. Isl. plants, 96 Sumatra plants (pres. by Arn. Arbor. in 1938), 32 Sumatra grasses (dupl. of U.S. Nat. Herb.). Philip. plants in: Herb. Univ. Michig. [MICH], Arn. Arbor. [A], Univ. of the Philip. [PUH].

Philippine collections distributed by the University of the Philippines, a.o. to Herb. Berkeley [UC].

According to Index Herb. (pt II, 1954) Java plants of his are in Herb. Sing. [SING], and Sarawak plants in Herb. Leiden [L]. Bartlett himself, however, assured me that he never collected in either place. The Sarawak plants must have been collected by E. Bartlett.
